Heartbeat bills are laws prohibiting abortion in most circumstances once a fetal heartbeat can be detected, and are common in US states. They have been criticised as poorly designed and disingenuous. In this letter to the editor I examine these criticisms.

This paper addresses a dichotomy in the attitudes of some clinicians and bioethicists regarding whether there is a moral difference between deactivating a cardiac pacemaker in a highly dependent patient at the end of life, as opposed to standard cases of withdrawal of treatment. Although many clinicians hold that there is a difference, some bioethicists maintain that the two sorts of cases are morally equivalent. The author explores one potential morally significant point of difference between pacemakers and certain other life-sustaining (...) treatments: specifically, that the former are biofixtures, which become part of the patient in a way that the latter do not. The concept of the pacemaker as biofixture grants pacemakers a unique moral status that gives reason to treat a pacemaker the same as other parts of the patient that are necessary to sustain life. The author employs this biofixture analysis to affirm the intuition that deactivating a pacemaker in a highly dependent patient at the end of life is, in moral terms, more analogous to active euthanasia than it is to standard cases of withdrawal of treatment. The paper concludes with consideration of potential implications for further implantable medical technologies, such as ventricular assist devices and total artificial hearts. (shrink)

There is an interesting historical detour in the dissemination of one of the seventeenth century’s most praised discoveries: the reception of Harvey’s account of the circulation of the blood is closely intertwined, especially in the Low Countries, with Descartes’ account of the origin of the heartbeat. Descartes was one of the first figures to support the circulation of the blood and to give credit to Harvey for it, although he presumably arrived at the same conclusion independently through his own anatomical (...) experiments. He did so while vocally rejecting Harvey’s views on the muscular nature of the heart and his explanation of cardiac motion, to promote his own mechanistic solutions instead. Although Descartes’ ..

Recently, several states in the United States have sought to adopt more restrictive abortion policies. Most have tried to enact “heartbeat bills” that prohibit most abortions once a fetal heartbeat becomes detectable. This article explores this question: Are heartbeat bills ethically defensible? I argue that they are not. There are at least four problems with them. First, heartbeat bills rely on a problematic understanding of human death. Second, they contradict and even undermine the leading arguments in ethics against abortion. Third, (...) they are ambiguous not just in terms of when they judge fetal heartbeats to be detectable but also in what they deem to be heartbeats. Finally, there is a case to be made that heartbeat bills are disingenuous, both in their intentions and in their underlying motives. (shrink)

To date, research examining the socio-spatial effects of smart city technologies have charted how they are reconfiguring the production of space, spatiality and mobility, and how urban space is governed, but have paid little attention to how the temporality of cities is being reshaped by systems and infrastructure that capture, process and act on real-time data. In this article, we map out the ways in which city-scale Internet of Things infrastructures, and their associated networks of sensors, meters, transponders, actuators and (...) algorithms, are used to measure, monitor and regulate the polymorphic temporal rhythms of urban life. Drawing on Lefebvre, and subsequent research, we employ rhythmanalysis in conjunction with Miyazaki’s notion of ‘algorhythm’ and nascent work on algorithmic governance, to develop a concept of ‘algorhythmic governance’. We then use this framing to make sense of two empirical case studies: a traffic management system and sound monitoring and modelling. Our analysis reveals: how smart city technologies computationally perform rhythmanalysis and undertake rhythm-making that intervenes in space-time processes; distinct forms of algorhythmic governance, varying on the basis of adaptiveness, immediacy of action, and whether humans are in-, on-, or, off-the-loop; and a number of factors that shape how algorhythmic governance works in practice.

In 2019, several US states passed “heartbeat” bills. Should such bills go into effect, they would outlaw abortion once an embryonic heartbeat can be detected, thereby severely limiting an individual’s access to abortion. Many states allow health care professionals to refuse to provide an abortion for reasons of conscience. Yet heartbeat bills do not include a positive conscience clause that would allow health care professionals to provide an abortion for reasons of conscience. I argue that this asymmetry is unjustified. The (...) same criteria that justify protecting conscientious refusals to provide abortion also justify protecting positive conscientious appeals regarding abortion. Thus, if the law provides legal exemptions for health care professionals who, as a matter of conscience, refuse to provide abortions where it is legal, it should also provide exemptions for health care professionals who, as a matter of conscience, feel obligated to provide abortions where it is illegal.

‘The doubtful story of successive events’. With these words Bernard Bosanquet is often taken to have damned historical knowledge to oblivion. Although it is undeniably true that Bosanquet uttered these words and saw them into print, it is much less clear what he intended their import to be and whether he intended to damn history as a form of knowledge as such. Although he wrote little directly which can be construed as ‘philosophy of history’, he developed views both implicitly and (...) explicitly which bear on this question. My concern in this paper is to show that Bosanquet’s animosity to history derived not from a desire to condemn, but from a desire to draw more from history than the historiography of his time would, in good philosophical conscience, allow him to. His words were words of disappointment and despair, of thwarted hope, rather than outright rejection. I shall argue that Bosanquet needed an account of historical experience to flesh out his account of the concrete universal. A re-telling of the story of Bosanquet and history shows how, if it had been possible for him to draw together unresolved strands in his thinking, he could have affirmed historical experience as ‘the heart beat of the absolute’. Following Foster I shall claim that he was ultimately committed to this, but was reluctant or unable to draw it out explicitly from his leading doctrines. (shrink)

In 1991, the University of Pittsburgh Medical Center implemented a policy that permitted the recovery of organs from cadavers pronounced dead using standardized cardiac criteria. This policy allowed families that had made a decision to forgo life sustaining treatment to then request organ donation. This entailed taking the patient to the operating room, discontinuing therapy, and after the patient is pronounced dead, procuring organs.

Among the various proposed ultrasound laws, a few have provisions that either provide the option for the pregnant woman to hear the heartbeat or require that the heartbeat be played and merely give the woman the option to somehow avert her ears. I will argue that these heartbeat provisions actually belie the argument that these laws are intended to assist autonomous choosing. Since the information could be provided just as easily through a factual statement , it cannot be justified to (...) involve emotions in a way that the pregnant woman did not autonomously choose for herself.

Arrhythmias are irregular heartbeats that may be life-threatening. Proper monitoring and the right care at the right time are necessary to keep the heart healthy. Monitoring electrocardiogram patterns on continuous monitoring devices is time-consuming. An intense manual inspection by caregivers is not an option. In addition, such an inspection could result in errors and inter-variability. This article proposes an automated ECG beat classification method based on deep neural networks to aid in the detection of cardiac arrhythmias. The data collected (...) by an Internet of Things enabled ECG monitoring device are transferred to a server. They are analysed by a deep learning model, and the results are shared with the primary caregiver. The proposed model is trained using the MIT-BIH ECG arrhythmia database to classify into four classes: normal beat, left bundle branch block beat, right bundle branch block beat, and premature ventricular contraction. The received data are sampled with an overlapping sliding window and divided into an 80:20 ratio for training and testing, with tenfold cross-validation. The proposed method achieves higher accuracy with a simple model without any preprocessing when compared with previous works. For the train and test sets, we achieved accuracy rates of 99.09 and 99.03%, respectively. A precision, recall, and F1 scores of 0.99 is obtained. The proposed model achieves its goal of developing a simple and accurate ECG monitoring system with improved performance. This simple and efficient deep learning approach for heartbeat classification could be applied in real-time telehealth monitoring systems. (shrink)

Psychology distinguishes between a bodily and a narrative self. Within neuroscience, models of the bodily self are based on exteroceptive sensorimotor processes or on the integration of interoceptive sensations. Recent research has revealed interactions between interoceptive and exteroceptive processing of self-related information, for example that mirror self-observation can improve interoceptive awareness. Using heartbeat perception, we measured the effect on interoceptive awareness of two experimental manipulations, designed to heighten attention to bodily and narrative aspects of the self. Participants gazed at a (...) photograph of their own face or at self-relevant words. In both experimental conditions interoceptive awareness was significantly increased, compared to baseline. Results show that attention to narrative aspects of self, previously regarded as relying on higher-order processes, has an effect similar to self-face stimuli in improving interoceptive awareness. Our findings extend the previously observed interaction between the bodily self and interoception to more abstract amodal representations of the self. (shrink)

Can we experience emotion without the feeling of accelerated heartbeats, perspiration, or other changes in the body? In his paper “What is an emotion”, William James famously claimed that “if we fancy some strong emotion and then try to abstract from our consciousness of it all the feelings of its bodily symptoms, we find we have nothing left behind” (1884, p. 193). Thus, bodily changes are essential to emotion. This is known as the Subtraction Argument. The Subtraction Argument is (...) still used to support Embodied theories of emotion. Proponents of Disembodied theories, however, have different intuitions regarding the role of bodily changes in the experience of emotion. In order to advance this debate, I conducted a series of studies testing people’s intuitions regarding the Subtraction Argument. Results show that, against James’ claims, most people consider that their hypothetical (Study 1) and actual (Study 2) emotions persist in the absence of bodily feelings. Furthermore, Study 1 found that participants’ responses were not related to individual differences in reflection or interoceptive awareness. These results pose a problem for Embodied theories of emotion and challenge extant explanations for the persistence of emotional experience in cases of impaired interoception. (shrink)

Attention to internal body sensations is practiced in most meditation traditions. Many traditions state that this practice results in increased awareness of internal body sensations, but scientific studies evaluating this claim are lacking. We predicted that experienced meditators would display performance superior to that of nonmeditators on heartbeat detection, a standard noninvasive measure of resting interoceptive awareness. We compared two groups of meditators (Tibetan Buddhist and Kundalini) to an age- and body mass index-matched group of nonmeditators. Contrary to our prediction, (...) we found no evidence that meditators were superior to nonmeditators in the heartbeat detection task, across several sessions and respiratory modulation conditions. Compared to nonmeditators, however, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier. These results provide evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest. (shrink)

A keen athlete in his late forties, philosophy professor Kevin Aho hadn't given much thought to his own mortality, until he suffered a sudden heart attack that left him fighting for his life. Confronted with death for the first time, he realized that the things he thought gave his life meaning, such as his independence or his ability to plan his own future, were in tatters. Aho turned to those thinkers who have reflected deeply on the meaning of life and (...) the anxiety of living when every heartbeat might be your last: the existentialists. Armed with insights from the likes of Kierkegaard, Heidegger, Nietzsche, and de Beauvoir, he found new meaning and comfort in a view of life that strives for authenticity and accepts aging and death as part of what makes life worthwhile. Existentialism asks us to face the frailty of our existence and to live with a sense of urgency and gratitude toward its manifold beauties. It is only then that we can be released from patterns of self-deception and begin to appreciate what truly matters in our fleeting, precious lives. (shrink)

The definition of death is one of the oldest and most enduring problems in biophilosophy and bioethics. Serious controversies over formally defining death began with the invention of the positive-pressure mechanical ventilator in the 1950s. For the first time, physicians could maintain ventilation and, hence, circulation on patients who had sustained what had been previously lethal brain damage. Prior to the development of mechanical ventilators, brain injuries severe enough to induce apnea quickly progressed to cardiac arrest from hypoxemia. Before the (...) 1950s, the loss of spontaneous breathing and heartbeat were perfect predictors of death because the functioning of the brain and of all other organs ceased rapidly and nearly simultaneously thereafter, producing a unitary death phenomenon. In the pretechnological era, physicians and philosophers did not have to consider whether a human being who had lost certain “vital functions” but had retained others was alive, because such cases were technically impossible. (shrink)

The distinction between the "permanent" (will not reverse) and "irreversible" (cannot reverse) cessation of functions is critical to understand the meaning of a determination of death using circulatory–respiratory tests. Physicians determining death test only for the permanent cessation of circulation and respiration because they know that irreversible cessation follows rapidly and inevitably once circulation no longer will restore itself spontaneously and will not be restored medically. Although most statutes of death stipulate irreversible cessation of circulatory and respiratory functions, the accepted (...) medical standard is their permanent cessation because permanence is a perfect surrogate indicator for irreversibility, and using it permits a more timely declaration. Therefore, patients properly declared dead in donation after circulatory death (DCD) protocols satisfy the requirements of death statutes and do not violate the dead donor rule. The acronym DCD should represent organ "donation after circulatory death" to clarify that the death standard is the permanent cessation of circulation, not heartbeat. Heart donation in DCD does not retroactively negate the donor's death determination because circulation has ceased permanently. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Notes and Fragments ENJOYING NEGATIVE EMOTIONS IN FICTIONS by John Morreall There is a puzzle going back to Aristotle and Augustine that has sometimes been called the "paradox of tragedy": how is it that nonmasochistic, nonsadistic people are able to enjoy watching or reading about fictional situations which are filled with suffering? The problem here actually extends beyond tragedy to our enjoyment of horror films and other fictional depictions (...) of situations which we would not enjoy in real life. What is it about fiction that turns intensely unpleasant situations into situations we can enjoy? Ofthe many solutions proposed to this puzzle, I shall mentionjust four. Aristotle held that in viewing tragedy we experience negative emotions — pity and fear — but get pleasure from the experience nonetheless because we are thereby purged of excess pity and fear. For Aristotle, too, there is a pleasure which tragedy shares with fiction in general, the delight we take in representations.1 Hume put more weight on this latter delight. Our pleasure in tragedy, he said, is based on our appreciation of the skill with which the literary or other artist has depicted the unpleasant scenes.2 Susan Feagin has recently located the pleasure we take in tragic art not in our direct responses to the work, which are "unpleasant experiences," she says, but in our meta-response of moral self-congratulation at these responses.3 The fourth solution to our puzzle is really a dissolution: it consists of denying that we actually feel fear, pity, and other negative emotions in our experience of fiction. The guiding principle here is that in order to have some emotion toward a situation, we must believe that it is a real situation. This principle is articulated in an influential article by Kendall Walton, though he does not apply it to our puzzle.4 95 96Philosophy and Literature I believe that this last solution is no solution at all because we do in fact feel emotions in our appreciation of fiction (a point I will develop later). The other three solutions above address the puzzle, and the pleasures they appeal to all have some explanatory power. But these solutions seem to me to overlook perhaps the most basic pleasure we take in tragedy, horror films, and the like — the direct pleasure of feeling (ear, pity, and similar emotions. The idea of enjoying negative emotions seems counterintuitive at first; indeed it may seem analytically false. But let us look more closely at those emotions to see what there might be to enjoy in them. Because the idea that we experience real emotions in response to fiction is controversial, we will begin not with fiction but with real life. After seeing how negative emotions can be enjoyed in real life, we can then consider their enjoyment in response to fiction. Fear is perhaps the most basic negative emotion, and at first glance one of the least likely to be enjoyed. To feel fear, many have claimed, we have tojudge that we are in danger, and danger is disturbing to us. And so it is natural that in fear there is the motivation to eliminate the danger, by fleeing, protecting ourselves, or attacking. Changes in the autonomic nervous system and the endocrine system equip us forjust such actions. They produce an increase in alertness and muscle tension, a faster and stronger heartbeat, a redistribution of the blood from the skin and internal organs to the voluntary muscles and brain, and a release of stored sugar from the liver into the bloodstream. Now although we may not be able to identify all these changes when we are in a state of fear, we can feel many of them directly, and we certainly feel the overall excitement which they produce. It is this excitement, I think, that makes fear potentially enjoyable. Especially for someone who leads a relatively dull life, the stimulation provided by fear can be pleasurable by contrast with the ordinary lack of stimulation. Many people, indeed, go to considerable trouble to put themselves into dangerous situations, in part, at least, for the thrill of fear that the danger will provide. Consider mountain climbers and skydivers, for instance. Now there are many sources... (shrink)

A trailblazing exploration of the political stakes of curiosity.

Conversing happily with my son we had been driving home when my mobile phone rang. Startled at the sound of my obstetrician's voice I had pulled off to the side of the road. At 18 weeks gestation I was told in a factual tone that the results from my serum screen had come back, indicating that our baby was at increased risk of Trisomy 18. Gripping the steering wheel my head had spun as he talked, explaining that Trisomy 18 was (...) worse than Trisomy 21 because our baby was not going to live. We had been thrilled when we heard the news of my pregnancy but now my temples throbbed and tears brimmed in my eyes. Suddenly my world was turned upside down and it had felt like someone reached into my chest and ripped my heart out.My husband and I decided that an amniocentesis was needed for a positive diagnosis and this was arranged for the following day. Studiously the sonographer performed the diagnostic ultrasound with a furrow across his brow. Watching the monitor I saw my baby moving as I watched the colours of red and blue flow through the heart and heard the regular, fast rhythm of the heartbeat. Quietly I hoped that the news was good but the creased brow had told me otherwise. Holding the amniotic fluid in his right hand the sonographer had glanced from it to me and empathetically informed me that the news wasn't good and that he didn't need to send the sample off for a positive diagnosis. Once again my world was crashing and all I wanted to do was bury my head in a pillow and sob. The following weekend dragged and had been filled with streams of tears and emotional turmoil. All I wanted to …. (shrink)

Over the past several years, the most widely publicized issue in capital litigation has been the constitutional status of states’ lethal injection protocols. Death row inmates have not challenged the constitutionality of lethal injection itself, but rather execution protocols and their potential for maladministration. The inmates’ concern is due to the three-drug protocol used in the vast majority of capital jurisdictions: if the anesthetic, which is administered first, is ineffectively delivered, then the second and third drugs — the paralytic and (...) heartbeat-ceasing agents — will cause torturous pain and suffering in violation of the Eight Amendment. Inmates have argued that the participation of anesthesiologists or other highly trained medical professionals is constitutionally required to minimize the risk of unnecessary suffering. This litigation, in conjunction with evidence that some executed inmates suffered torturous pain, has reinvigorated the ethical debate about physician participation in executions. Even though the United States Supreme Court has signaled that physician participation is not constitutionally required, lawmakers in death penalty states must consider the ethics of physician involvement.

The ArgumentThe development of modern mathematical biology took place in the 1920s in three main directions: population dynamics, population genetics, and mathematical theory of epidemics. This paper focuses on the first trend which is considered the most significant. Modern mathematical theory of population dynamics is characterized by three aspects (the first two being in a somewhat critical relationship): the emergence of the mathematical modeling approach, the attempt at establishing it in a reductionist-mechanist conceptual framework, and the revival of Darwinism. The (...) first section is devoted to the analysis of the concept of mathematical model and the second one presents an example of a mathematical model (Van der Pol's model of heartbeat) which is a good prototype of that concept. In section 3 the main trends of mathematization of biology and the cultural and scientific contexts in which they found their development are discussed. Sections 4 and 5 are devoted to the contributions of V. Volterra and A. J. Lotka, to the analysis of the differences of their scientific conceptions, and to a discussion of a case study: the priority dispute concerning the discovery of the Volterra-Lotka equations. The historical analysis developed in this paper is also intended to detect the roots of some recent trends of mathematization of biology. (shrink)

In René Descartes' works there are four major references to living bodies as objects of his natural philosophy. The first is contained in the Fifth part of the Discours de la Méthode, published in June 1637, where Descartes provides a mechanical explanation of the heartbeat and other living functions of the body. The second is in a bio-medical note collected in the Excerpta anatomica dated November 1637, where he discusses nutrition and growth. The third is the famous claim on the (...) absence of a section on living bodies in the Principia philosophiae, published in 1644. The fourth is in La Description du corps humain, Descartes' late physiology likely dated 1647-1648. In this article, by exploring these passages and contextualizing his physiological observations of animals and plants, I reassemble Descartes' science of life: his dismissal of soul, his mechanical framework, his interpretation of bodily self-maintenance and growth, his understanding of living bodies as integrated and organic systems, and the role of a power such as the immutatio and forces such as the impetus.

Neurons run on electricity 1, producing many impulses each second when they are working hard. These brief (1/1000 second, as rapid as a fast camera shutter), 0.1 volt impulses (though a hundred times smaller if recorded from outside the cell) can be amplified and heard via a loudspeaker. Neurophysiologists routinely listen to neurons via loudspeakers in their laboratories, much as anesthesiologists listen to a patient's heartbeat in the operating room.

During 1992, academic bioethicists celebrated the 30th anniversary of bioethics. Some like to date the origin of modern secular bioethics to the advent of transplant technology that began with kidney transplantation in the early 1960s in the Seattle, Washington, area. This is certainly a good candidate for a starting point. Another might be the work of Joseph Fletcher in the New York area with the Euthanasia Society of America and with clergy training. Still another candidate for the origins of secular (...) bioethics would be the trial of physicians at the University of Virginia for transplanting a kidney at which the same Joseph Fletcher testified. At that trial, the alteration occurred in American law from a definition of death that focused on the cessation of heartbeat to one that focused on the cessation of brain function. (shrink)

ObjectivePrevious research has shown reduced interoceptive accuracy in depression. Attention deficit represents a key symptom of depression. Moreover, IAcc is positively correlated with attention. There is no study that investigates the effect of depression on IAcc and attention. The aim of this study is to examine the mediating effect of IAcc on depression and attention.MethodsThirty-six depressed patients from the Psychosomatic Clinic in Windach were matched with 36 healthy controls according to age and sex and were assessed at Ulm University. All (...) participants completed the Beck Depression Inventory-II, the heartbeat perception task to examine IAcc, and the d2 test assessing selective attention.ResultsDepressed patients showed attention deficits—both for general visual attention and IAcc—compared to healthy controls. The mediation analyses revealed that the relationship between depression and attention is not mediated via IAcc. Furthermore, depression predicts IAcc and attention, but these effects are direct and largely unaffected by the respective other variable.DiscussionThe results of the present study highlight both interoceptive as well as attention deficits in depressed patients. No clear mediation between these variables could be shown in this study. More elaborative research is needed to clarify whether different approaches to improve IAcc are effective for these deficits in depressed patients and could therefore be of importance as an additional aspect of therapy in depression.

CEOs’ social and environmental activism attracts significant public and research interest. Positioned as an expression of personal morality, such activism is potentially highly influential because of CEOs’ public visibility and associated positional and resource-based power. This paper questions the assumption that CEO activism can only be explained in relation to individual moral action, and illuminates its wider social implications. We critically evaluate the recent upsurge in CEO activism by juxtaposing it against broader social activism, identifying its distinctive characteristics, and empirically (...) examining two recent ‘moral episodes’: the Deferred Action for Childhood Arrivals program and the Fetal Heartbeat Acts. Our analysis demonstrates that CEO activism is more heterogeneous than research to date has shown. Building on this analysis, a refined understanding of the character and morality of CEO activism is developed by establishing a typology of its forms. We conclude that while CEO activism is an important and potent new phenomenon, it may not be universally appropriate to regard CEOs as moral leaders. Instead, it is paramount to question the motives and effects of what CEOs do in the name of morality. (shrink)

Although it is commonly believed that the concept of brain death was developed to benefit organ transplants, it evolved independently. Transplantation owed its development to advances in surgery and immunosuppressive treatment; BD owed its origin to the development of intensive care. The first autotransplant was achieved in the early 1900s, when studies of increased intracranial pressure causing respiratory arrest with preserved heartbeat were reported. Between 1902 and 1950, the BD concept was supported by the discovery of EEG, Crile’s definition of (...) death, the use of EEG to demonstrate abolition of brain potentials after ischaemia, and Crafoord’s statement that death was due to cessation of blood flow. Transplantation saw the first xenotransplant in humans and the first unsuccessful kidney transplant from a cadaver. In the 1950s, circulatory arrest in coma was identified by angiography, and the death of the nervous system and coma dépassé were described. Murray performed the first successful kidney transplant. In the 1960s, the BD concept and organ transplants were instantly linked when the first kidney transplant using a brain-dead donor was performed; Schwab proposed to use EEG in BD; the Harvard Committee report and the Sydney Declaration appeared; the first successful kidney, lung and pancreas transplants using cadaveric donors were achieved; Barnard performed the first human heart transplant. This historical review demonstrates that the BD concept and organ transplantation arose separately and advanced in parallel, and only began to progress together in the late 1960s. Therefore, the BD concept did not evolve to benefit transplantation. (shrink)

Test anxiety is a widespread and primarily detrimental emotion in learning and achievement settings. This research aimed to explore the autonomic nervous system response patterns of test-anxious individuals in response to evaluative stress. By presenting a standard interview task, an evaluative scenario was effectively induced. Heart rate variability, a biomarker that can accurately reflect the ANS activity, was used to reflect the physiological responses of 48 high test-anxious subjects and 49 low test-anxious subjects. Results indicate that: both groups show a (...) significantly increased emotional arousal in the evaluative scenario; high test-anxious individuals show a significantly decreased emotional pleasantness in the evaluative scenario, whereas low test-anxious individuals show no significant changes; both groups show a significantly increased low-frequency HRV; high test-anxious individuals show a significantly decreased high-frequency HRV and root mean square of successive heartbeat interval differences, whereas low test-anxious individuals remain stable. These findings suggest that high test-anxious individuals display an increased sympathetic nervous system activity and a decreased parasympathetic nervous system activity in response to evaluative stress, while low-anxious individuals display an increased SNS activity and a stable PNS activity in response to evaluative stress.

This paper presents a new line of inquiry into when and how music as a semiotic system was born. Ten principal expressive aspects of music retain specific structural patterns to signify a certain affective state, which distinguishes the tonal organization of music from the phonetic and prosodic organization of natural languages. Therefore, the question of music’s origin can be answered by establishing the point in human history, at which expressive aspects might have been abstracted from the instinct-driven primate calls and (...) used to express human psycho-emotional states. Etic analysis of acoustic parameters is the prime means of cross-comparison of the typical patterns of expression of the same basic emotions in human music versus animal vocal communication. A new method of such analysis is proposed here. Formation of such expressive aspects as meter, tempo, melodic intervals, and articulation can be explained by the influence of bipedal locomotion, breathing cycle, and heartbeat, long before Homo sapiens. However, two aspects, rhythm and melodic contour, most crucial for music as we know it, lack proxies in the Paleolithic lifestyle. The available ethnographic and developmental data leads one to believe that rhythmic and directional patterns of melody became involved in conveying emotion-related information as a result of frequent switching from one call-type to another within the limited repertory of calls adopted for ongoing caretaking of human youngsters and domestic animals. The efficacy of rhythm and pitch contour in affective communication must have been discovered spontaneously in new important cultural activities. The most likely scenario for music to have become fully semiotically functional is the formation of cross-specific communication between humans and domesticated animals during the Neolithic demographic explosion. The model of such communication can be found in the surviving tradition of Scandinavian pastoral music. This article discusses the most likely ways in which such music evolved. (shrink)

While linear time results from the measurement of physical events, the temporality of life is characterized by cyclical processes, which also manifest themselves in subjective bodily experience. This applies for the periodicity of heartbeat, respiration, sleep-wake cycle, or circadian hormone secretion, among others. The central integration of rhythmic bodily signals in the brain forms the biological foundation of the phenomenal sense of temporal continuity. Cyclical repetitions are also found in the recurring phases of need, drive, and satisfaction. Finally, the cyclical (...) structure of bodily time manifests itself at an extended level in the form of implicit or body memory. However, this cyclical structure of lived time comes into tension with the orders of linear time which have been increasingly established in Western societies since the modern age. This tension creates both individual as well as societal conflicts and may also result in psychopathological phenomena. As an example, depression and burn-out syndromes will be discussed. (shrink)

While philosophers have, for centuries, pondered upon the relation between mind and brain, neuroscientists have only recently been able to explore the connection analytically — to peer inside the black box. This ability stems from recent advances in technology and emerging neuroimaging modalities. It is now possible not only to produce remarkably detailed images of the brain’s structure (i.e. anatomical imaging) but also to capture images of the physiology associated with mental processes (i.e. functional imaging). We are able to see (...) how specific regions of the brain ‘light up’ when activities such as reading this book are performed, and how our neurons and their elaborate cast of supporting cells organize and coordinate their tasks. As demonstrated in the other chapters of this book, the mapping of the human mind (mostly by measuring regional changes in blood flow, initially by positron emission tomography (PET) and recently by functional magnetic resonance imaging or (fMRI)) has provided insight into the functional neuroanatomy of neuropsychiatric diseases. Amazingly, the idea that regional cerebral blood flow (rCBF) is related intimately to brain function goes back more than a century. As is often the case in science, this idea was initially the result of unexpected observations. The Italian physiologist Angelo Mosso first expressed the idea while studying pulsations of the living human brain that keep pace with the heartbeat (Mosso, 1881). These brain pulsations can be observed on the surface of the fontanelles in newborn children. Mosso believed that they reflected blood flow to the brain. He observed similar pulsations in an adult with a post-traumatic skull defect over the frontal lobes. While studying this subject, a peasant named Bertino, Mosso observed a sudden increase in the magnitude of the ‘brain’s heart-beats’ when the church bells signalled 12 o’clock, the time for a required prayer. The changes in brain pulsations occurred independently of any change in pulsations in the forearm.. (shrink)

Derrida is one of those annoying geniuses you can take a class on, read half-a-dozen books by and still have no idea what he’s talking about. Derrida’s ‘writing’ is definitely confusing (it’s like he’s pulling the rug out from under the rug that he pulled out from under philosophy). But beneath the confusion, like the heartbeat of a bird in your hand, you can feel Derrida’s electric genius. It draws you to it; you want to understand it…but it’s so confusing. (...) Jim Powell’s Derrida For Beginners is the clearest explanation of Derrida and deconstruction presently available in our solar system. Powell guides us through blindingly obscure texts like Grammatology (Derrida’s deconstruction of Saussure, Le;vi Strauss, Roussseau), “Diffe;rance” (his essay on language and life), Dissemination (his dismantling of Plato, his rap on Mallarme;), along with his other masterpieces.

Does it matter that the hearts of 'brainstem dead' patients may persist in beating spontaneously? Hostile reactions, to the Danish inclusion of cardiac criteria in the determination of death, betray reductionist views of human life at the core of 'brainstem' conceptions of death. Such views (whether centred on neurological function or on abstractions concerning 'personhood') supplant the richness of human life and death with the poverty of essentialism: and mask the lethal nature of beating-heart organ retrieval. The affirmation of cardiac (...) criteria for death is not an alternative form of essentialism as some critics suppose, but part of an understanding of human life and death which rejects essentialism altogether. The spontaneously persistent heartbeat does not constitute human life, but most certainly counts for it. (shrink)

Unlike sonographic examinations, sonic fetal heartbeat monitoring has received relatively little attention from scholars in the social sciences. Using the case of fetal heartbeat monitoring as part of midwifery prenatal care in Germany, this contribution introduces music as an analytical tool for exploring the aesthetic dimensions of obstetrical surveillance practices. Based on ethnographic stories, three orchestrations are compared in which three different instruments help audiences to listen to what becomes fetal heartbeat music and to qualify fetal and pregnant lives in (...) relation to each other. In the Doppler-based orchestration, audible heartbeat music is taken as a sign of a child in need of parental love and care cultivated to listen. The Pinard horn makes esoteric fetal music that can be appreciated by the midwife as a skilled instrumentalist alone and helps to enact a child hidden in the belly. The cardiotocograph brings about soothing music and a reassuring relationship with a child but also durable scripts of juridical beauty. This material-semiotic analysis amplifies how well-being is shaped in midwifery prenatal care practices. (shrink)

Although it is commonly believed that the concept of brain death was developed to benefit organ transplants, it evolved independently. Transplantation owed its development to advances in surgery and immunosuppressive treatment; BD owed its origin to the development of intensive care. The first autotransplant was achieved in the early 1900s, when studies of increased intracranial pressure causing respiratory arrest with preserved heartbeat were reported. Between 1902 and 1950, the BD concept was supported by the discovery of EEG, Crile’s definition of (...) death, the use of EEG to demonstrate abolition of brain potentials after ischaemia, and Crafoord’s statement that death was due to cessation of blood flow. Transplantation saw the first xenotransplant in humans and the first unsuccessful kidney transplant from a cadaver. In the 1950s, circulatory arrest in coma was identified by angiography, and the death of the nervous system and coma dépassé were described. Murray performed the first successful kidney transplant. In the 1960s, the BD concept and organ transplants were instantly linked when the first kidney transplant using a brain-dead donor was performed; Schwab proposed to use EEG in BD; the Harvard Committee report and the Sydney Declaration appeared; the first successful kidney, lung and pancreas transplants using cadaveric donors were achieved; Barnard performed the first human heart transplant. This historical review demonstrates that the BD concept and organ transplantation arose separately and advanced in parallel, and only began to progress together in the late 1960s. Therefore, the BD concept did not evolve to benefit transplantation. (shrink)

Since the middle of the 20th century our ability to manage death has changed. The dying of a human being can be hastened, slowed or even forestalled. As a result we need to reconsider death as a prerequisite for organ donation and hence the brain death criterion. In Germany, the debate about that criterion has been going on for some months. The author outlines that debate and discusses problems arising from a new category of donors, the so-called non-heartbeating donors. He (...) explains what consequences follow for the ethics of organ donation, especially for the notion of death as its prerequisite. Im vorliegenden Beitrag zeichnet der Autor zunächst die Grundzüge der Hirntod-Debatte nach. Daran anschließend setzt er sich mit der Problematik der neuen Spendergruppe der non-heartbeating donors auseinander. Am Ende erläutert der Autor, welche Konsequenzen daraus für die Ethik der Organspende, genau genommen für die Rolle des Todes als Voraussetzung der Organspende, zu ziehen sind. (shrink)
