Stress profoundly impacts quality of life and may lead to various diseases and conditions. Understanding the underlying physiological and neurological processes that take place during stress and meditation techniques may be critical for effectively treating stress-related diseases. The article examines a hypothetical physiological homeostatic response that compares and contrasts changes in central and peripheral oscillations during stress and meditation, and relates these to changes in the autonomic system and neurological activity. The authors discuss how cardiorespiratory synchronization, which occurs during the (...) parasympathetic response and meditation, influences and modulates activity and oscillations of the brain and autonomic nervous system. Evidence is presented on how synchronization of cardiac and respiratory rates during meditation may lead to a homeostatic increase in cellular membrane potentials in neurons and other cells throughout the body. These potential membrane changes may underlie the reduced activity in the amygdala, and other cortical areas during meditation, and research examining these changes may foster better understanding of the restorative properties and health benefits of meditation.

High blood pressure is an important component of pre-eclampsia. The underlying mechanism of development of hypertension in pre-eclampsia is complicated and still remains obscure. Several theories have been advanced including endothelial dysfunction, uteroplacental insufficiency leading to generalized vasoconstriction, increased cardiac output, and sympathetic hyperactivity. Increased blood flow and pressure are thought to lead to capillary dilatation, which damages end-organ sites, leading to hypertension, proteinuria and edema. Additional theories have been put forward based on epidemiological research, implicating immunological and genetic factors. (...) None of these theories have been substantiated. Based on a review of literature this paper postulates that the initiating event for the development of preeclampsia is intermittent hypoxia associated with irregular breathing during sleep, hypoapnea, apnea,inadequate respiratory excursions during the waking hours and inadequate cardiopulmonary synchronization (abnormal sympatho-vagal balance).

Recent fndings illustrate how changes in consciousness accommodated by neural correlates and plasticity of the brain advance a model of perceptual change as a function of meditative practice. During the mindbody response neural correlates of changing awareness illustrate how the autonomic nervous system shifts from a sympathetic dominant to a parasympathetic dominant state. Expansion of awareness during the practice of meditation techniques can be linked to the Default Mode Network (DMN), a network of brain regions that is active when the (...) one is not focused on the outside world and the brain is restful yet awake (Chen et al., 2008). A model is presented illustrating the dynamic mindbody response before and after mindfulness meditation, and connections are made with prefrontal cortex activity, the cardiac and respiratory center, the thalamus and amygdala, the DMN and cortical function connectivity. The default status of the DMN changes corresponding to autonomic modulation resulting from meditation practice. (shrink)

Mind-body therapies have been shown to be effective in clinical treatment of disorders such as high blood pressure and stress. Significant differences in the effectiveness of mind–body therapies have been shown and a common link among the therapies has yet to be defined. This article overviews the role of slow rhythmic breathing in physiological as well as therapeutic effects of mind-body therapies. Slow deep breathing practice has important implications as it may underlie the basic mechanism that synchronizes the brain with (...) the autonomic response. This article reviews studies that include the effect of deep slow breathing with or without mind-body therapy exercises. In utero studies that monitor patterns of fetal breathing reveal sympathetic activation with irregular, shallow fast breathing movements compared to slow deep breathing. Recognition of respiratory mechanisms in mind-body therapies can lead to development of more effective relaxation exercises that may incorporate deep slow breathing in clinical applications.

The Global Workspace Theory and Information Integration Theory are two of the most currently accepted consciousness models; however, these models do not address many aspects of conscious experience. We compare these models to our previously proposed consciousness model in which the thalamus fills-in processed sensory information from corticothalamic feedback loops within a proposed 3D default space, resulting in the recreation of the internal and external worlds within the mind. This 3D default space is composed of all cells of the body, (...) which communicate via gap junctions and electrical potentials to create this unified space. We use 3D llustrations to explain how both visual and non-visual sensory information may be filled-in within this dynamic space, creating a unified seamless conscious experience. This neural sensory memory space is likely generated by baseline neural oscillatory activity from the default mode network, other salient networks, brainstem, and reticular activating system.

Understanding the autonomic nervous system and homeostatic changes associated with emotions remains a major challenge for neuroscientists and a fundamental prerequisite to treat anxiety, stress, and emotional disorders. Based on recent publications, the inter-relationship between respiration and emotions and the influence of respiration on autonomic changes, and subsequent widespread membrane potential changes resulting from changes in homeostasis are discussed. We hypothesize that reversing homeostatic alterations with meditation and breathing techniques rather than targeting neurotransmitters with medication may be a superior method (...) to address the whole body changes that occur in stress, anxiety, and depression. Detrimental effects of stress, negative emotions, and sympathetic dominance of the autonomic nervous system have been shown to be counteracted by different forms of meditation, relaxation, and breathing techniques. We propose that these breathing techniques could be used as firstline and supplemental treatments for stress, anxiety, depression, and some emotional disorders. (shrink)

Pranayamic breathing, defined as a manipulation of breath movement, has been shown to contribute to a physiologic response characterized by the presence of decreased oxygen consumption, decreased heart rate, and decreased blood pressure, as well as increased theta wave amplitude in EEG recordings, increased parasympathetic activity accompanied by the experience of alertness and reinvigoration. The mechanism of how pranayamic breathing interacts with the nervous system affecting metabolism and autonomic functions remains to be clearly understood. It is our hypothesis that voluntary (...) slow deep breathing functionally resets the autonomic nervous system through stretchinduced inhibitory signals and hyperpolarization currents propagated through both neural and non-neural tissue which synchronizes neural elements in the heart, lungs, limbic system and cortex. During inspiration, stretching of lung tissue produces inhibitory signals by action of slowly adapting stretch receptors (SARs) and hyperpolarization current by action of fibroblasts. Both inhibitory impulses and hyperpolarization current are known to synchronize neural elements leading to the modulation of the nervous system and decreased metabolic activity indicative of the parasympathetic state. In this paper we propose pranayama’s physiologic mechanism through a cellular and systems level perspective,involving both neural and non-neural elements. This theoretical description describes a common physiological mechanism underlying pranayama and elucidate the role of the respiratory and cardiovascular system on modulating the autonomic nervous system. Along with facilitating the design of clinical breathing techniques for the treatment of autonomic nervous system and other disorders, this model will also validate pranayama as a topic requiring more research.

The human eyes and brain, which have finite boundaries, create a ‘‘virtual’’ space within our central nervous system that interprets and perceives a space that appears boundless and infinite. Using insights from studies on the visual system, we propose a novel fast processing mechanism involving the eyes, visual pathways, and cortex where external vision is imperceptibly processed in our brain in real time creating an internal representation of external space that appears as an external view. We introduce the existence of (...) a three-dimension default space consisting of intrapersonal body space that serves as the framework where visual and non-visual sensory information is sensed and experienced. We propose that the thalamus integrates processed information from corticothalamic feedback loops and fills-in the neural component of 3D default space with an internal visual representation of external space, leading to the experience of visual consciousness. This visual space inherently evades perception so we have introduced three easy clinical tests that can assist in experiencing this visual space. We also review visual neuroanatomical pathways, binocular vision, neurological disorders, and visual phenomenon to elucidate how the representation of external visible space is recreated within the mind.

Respiration influences various pacemakers and rhythms of the body during inspiration and expiration but the underlying mechanisms are relatively unknown. Understanding this phenomenon is important, as breathing disorders, breath holding, and hyperventilation can lead to significant medical conditions. We discuss the physiological modulation of heart rhythm, blood pressure, sympathetic nerve activity, EEG, and other changes observed during inspiration and expiration. We also correlate the intracellular mitochondrial respiratory metabolic processes with real-time breathing and correlate membrane potential changes with inspiration and expiration. (...) We propose that widespread minor hyperpolarization occurs during inspiration and widespread minor depolarization occurs during expiration. This depolarization is likely a source of respiratory drive. Further knowledge of intracellular and extracellular ionic changes associated with respiration will enhance our understanding of respiration and its role as a modulator of cellular membrane potential. This could expand treatment options for a wide range of health conditions, such as breathing disorders, stress-related disorders, and further our understanding of the Hering–Breuer reflex and respiratory sinus arrhythmia.

The role of the physiological processes involved in human vision escapes clarification in current literature. Many unanswered questions about vision include: 1) whether there is more to lateral inhibition than previously proposed, 2) the role of the discs in rods and cones, 3) how inverted images on the retina are converted to erect images for visual perception, 4) what portion of the image formed on the retina is actually processed in the brain, 5) the reason we have an after-image with (...) antagonistic colors, and 6) how we remember space. This theoretical article attempts to clarify some of the physiological processes involved with human vision. The global integration of visual information is conceptual; therefore, we include illustrations to present our theory. Universally, the eyeball is 2.4 cm and works together with membrane potential, correspondingly representing the retinal layers,photoreceptors, and cortex. Images formed within the photoreceptors must first be converted into chemical signals on the photoreceptors’ individual discs and the signals at each disc are transduced from light photons into electrical signals. We contend that the discs code the electrical signals into accurate distances and are shown in our figures. The pre-existing oscillations among the various cortices including the striate and parietal cortex,and the retina work in unison to create an infrastructure of visual space that functionally ‘‘places” the objects within this ‘‘neural” space. The horizontal layers integrate all discs accurately to create a retina that is pre-coded for distance. Our theory suggests image inversion never takes place on the retina,but rather images fall onto the retina as compressed and coiled, then amplified through lateral inhibition through intensification and amplification on the OFF-center cones. The intensified and amplified images are decompressed and expanded in the brain, which become the images we perceive as external vision. (shrink)

Understanding the mechanics of consciousness remains one of the most important challenges in modern cognitive science. One key step toward understanding consciousness is to associate unconscious physiological processes with subjective experiences of sensory, motor, and emotional contents. This article explores the role of various cellular membrane potential differences and how they give rise to the dynamic infrastructure of conscious experience. This article explains that consciousness is a body-wide, biological process not limited to individual organs because the mind and body are (...) unified as one entity; therefore, no single location of consciousness can be pinpointed. Consciousness exists throughout the entire body, and unified consciousness is experienced and maintained through dynamic repolarization during inhalation and expiration. Extant knowledge is reviewed to provide insight into how differences in cellular membrane potential play a vital role in the triggering of neural and non-neural oscillations. The role of dynamic cellular membrane potentials in the activity of the central nervous system, peripheral nervous system, cardiorespiratory system, and various other tissues (such as muscles and sensory organs) in the physiology of consciousness is also explored. Inspiration and expiration are accompanied by oscillating membrane potentials throughout all cells and play a vital role in subconscious human perception of feelings and states of mind. In addition, the role of the brainstem, hypothalamus, and complete nervous system (central, peripheral, and autonomic)within the mind-body space combine to allow consciousness to emerge and to come alive. This concept departs from the notion that the brain is the only organ that gives rise to consciousness. (shrink)

Our experiences with the external world are possible mainly through vision, hearing, taste, touch, and smell providing us a sense of reality. How the brain is able to seamlessly integrate stimuli from our external and internal world into our sense of reality has yet to be adequately explained in the literature. We have previously proposed a three-dimensional unified model of consciousness that partly explains the dynamic mechanism. Here we further expand our model and include illustrations to provide a better conception (...) of the ill-defined space within the self, providing insight into a unified mind-body concept. In this article, we propose that our senses “super-impose” on an existing dynamic space within us after a slight, imperceptible delay. The existing space includes the entire intrapersonal space and can also be called the “the body’s internal 3D default space”. We provide examples from meditation experiences to help explain how the sense of ‘self’ can be experienced through meditation practice associated with underlying physiological processes that take place through cardio-respiratory synchronization and coherence that is developed among areas of the brain. Meditation practice can help keep the body in a parasympathetic dominant state during meditation, allowing an experience of inner ‘self’. Understanding this physical and functional space could help unlock the mysteries of the function of memory and cognition, allowing clinicians to better recognize and treat disorders of the mind by recommending proven techniques to reduce stress as an adjunct to medication treatment.

Current research on the various forms of autoscopic phenomena addresses the clinical and neurological correlates of out-of-body experiences, autoscopic hallucinations,and heautoscopy. Yet most of this research is based on functional magnetic resonance imaging results and focuses predominantly on abnormal cortical activity. Previously we proposed that visual consciousness resulted from the dynamic retinogeniculo-cortical oscillations, such that the photoreceptors dynamically integrated with visual and other vision-associated cortices, and was theorized to be mapped out by photoreceptor discs and rich retinal networks which synchronized (...) with the retinotopic mapping and the associated cortex. The feedback from neural input that is received from the thalamus and cortex via retinogeniculo-cortical oscillations and sent to the retina is multifold higher than feed-forward input to the cortex. This can effectively translate into out-of-body experiences projected onto the screen formed by the retina as it is perceived via feedback and feed-forward oscillations from the reticular thalamic nucleus, or “internal searchlight”. This article explores the role of the reticular thalamic nucleus and the retinogeniculo-cortical oscillations as pivotal internal components in vision and various autoscopic phenomena. (shrink)

Science and Homosexualities is the first anthology by historians of science to examine European and American scientific research on sexual orientation since the coining of the word "homosexual" almost 150 years ago. This collection is particularly timely given the enormous scientific and popular interest in biological studies of homosexuality, and the importance given such studies in current legal, legislative and cultural debates concerning gay civil rights. However, scientific and popular literature discussing the biology of sexual orientation have been short-sighted in (...) representing it as objective, new scientific work. This volume demonstrates that the quest for the biological "cause" of homosexuality and other sexualities is as old as the term itself. These essays explore the active role experimental subjects played in shaping scientific theories of homosexuality and cultural perceptions of sexuality and sexual identity. Finally this anthology studies the way in which this doctor-patient interaction shaped not only scientific theories of homosexuality, but also cultural perceptions and self-identities as well. Contributors include: Garland E. Allen, Erin G. Carlston, Julian Carter, Alice D. Dreger, Anne Fausto-Sterling, Margaret Gibson, Stephanie Kenen, Hubert Kennedy, Harry Oosterhuis, James Steakley, Richard Pillard, Jennifer Terry. (shrink)

"Learning By All Means" presents a modern philosophy of education that exhibits the aesthetic face of learning in all of its varieties. Concentrating on the concept of learning, rather than teaching, and offering a philosophical rather than psychological approach, this book asks such fundamental questions as: How, what, why, and where do we learn? What are the roles of reason and imagination in learning? What are the differences and relations among learning by instruction, by practice, by example, and by reflection? (...) How are the standards and values of particular fields and disciplines communicated and interpreted? How do traditional practices shape us even as we strive to go beyond them? And finally, how are our sensibilities, our very Selves, transformed by learning? Responding to such questions, "Learning By All Means" challenges established learning theories by stressing the personal struggle for competency and creativity. (shrink)

The three dialogues in this contribution concern 21st century application of life‐like robots in the care of older adults. They depict conversations set in the near future, involving a philosopher (Dr Phonius) and a nurse (Dr Myloss) who manages care at a large facility for assisted living. In their first dialogue, the speakers discover that their quite different attitudes towards human‐robot interaction parallel fundamental differences separating their respective concepts of consciousness. The second dialogue similarly uncovers deeply contrasting notions of personhood (...) that appear to be associated with respective communities of nursing and robotics. The additional key awareness that arises in their final dialogue links applications of life‐like robots in the care of older adults with potential transformations in our understandings of ourselves – indeed, in our understandings of the nature of our own humanity. This series of dialogues, therefore, appears to address a topic in nursing philosophy that merits our careful attention. (shrink)

Ambitious targets to reduce greenhouse gas emissions from agriculture have been set by both national governments and their respective livestock sectors. We hypothesize that farmer self-identity influences their assessment of climate change and their willingness to implement measures which address the issue. Perceptions of climate change were determined from 286 beef/sheep farmers and evaluated using principal component analysis. The analysis elicits two components which evaluate identity, and two components which evaluate behavioral capacity to adopt mitigation and adaptation measures. Subsequent Cluster (...) Analyses reveal four farmer types based on the PCA scores. ‘The Productivist’ and ‘The Countryside Steward’ portray low levels of awareness of climate change, but differ in their motivation to adopt pro-environmental behavior. Conversely, both ‘The Environmentalist’ and ‘The Dejected’ score higher in their awareness of the issue. In addition, ‘The Dejected’ holds a high sense of perceived risk; however, their awareness is not conflated with an explicit understanding of agricultural GHG sources. With the exception of ‘The Environmentalist’, there is an evident disconnect between perceptions of agricultural emission sources and their contribution towards GHG emissions amongst all types. If such linkages are not conceptualized, it is unlikely that behavioral capacities will be realized. Effective communication channels which encourage action should target farmers based on the groupings depicted. Therefore, understanding farmer types through the constructs used in this study can facilitate effective and tailored policy development and implementation. (shrink)

The sudden emergence of the COVID-19 pandemic brought global disruption to every aspect of society including healthcare, supply chain, the economy, and social interaction. Among the many emergent considerations were the safety and public health of the public, patients, essential workers, and healthcare professionals. In certain locations, clinical research was halted—or terminated—in deference to the immediate needs of patient care, and clinical trials focusing on the treatment and prevention of coronavirus infection were prioritized over studies focusing on other diseases. Difficult (...) decisions were made rapidly; flexibility and reconsideration were necessary not only because the intensity and severity of infection varied over time and by locale but also because knowledge of the disease and understanding of its treatment grew. Here we discuss the ethical challenges in decision-making and competing ethical tensions during the pandemic in an effort to advance future preparedness. (shrink)

The present study examines the relationships between consumers'' ethical beliefs and personality traits. Based on a survey of 295 undergraduate business students, the authors found that individuals with high needs for autonomy, innovation, and aggression, as well as individuals with a high propensity for taking risks tend to have less ethical beliefs concerning possible consumer actions. Individuals with a high need for social desirability and individuals with a strong problem solving coping style tend to have more ethical beliefs concerning possible (...) consumer actions. The needs for achievement, affiliation, complexity and an emotion solving coping style were not significantly correlated with consumer ethical beliefs. (shrink)

Mark Vernon links the resources of the philosophical tradition with numerous illustrations from modern culture to ask what friendship is and how it relates to sex, work, politics and spirituality. Unusually, he argues that Plato and Nietzsche, as much as Aristotle and Aelred, should be put center stage. Their penetrating and occasionally tough insights are invaluable if friendship is to be a full, not merely sentimental, way of life for today.

This being so it may as well be placed in a position that confers desirable attributes to the arrangement of the elements, while notionally recognising its lineage to the group 1 alkali metals and the group 17 halogens.

Cosmopolitan theory suggests that we should shift our moral attention from the local to the global. Richard Vernon argues, however, that if we adopt cosmopolitan beliefs about justice we must re-examine our beliefs about political obligation. Far from undermining the demands of citizenship, cosmopolitanism implies more demanding political obligations than theories of the state have traditionally recognized. Using examples including humanitarian intervention, international criminal law, and international political economy, Vernon suggests we have a responsibility not to enhance risks (...) facing other societies and to assist them when their own risk-taking has failed. The central arguments in Cosmopolitan Regard are that what we owe to other societies rests on the same basis as what we owe to our own, and that a theory of cosmopolitanism must connect the responsibilities of citizens beyond their own borders with their obligations to one another"--Provided by publisher.

The extraordinary story of Krishnamurti, hailed early in life as the messiah for the 20th century, is told here in the light of a century of changing spiritual attitudes. It is a tale of mysticism, sexual scandals, religious fervor and chicanery, out of which emerged one of the most influential thinkers of modern times. Krishnamurti was "discovered" as a young boy on a beach in India by members of the Theosophical Society, convinced that they had found the new world leader, (...) a spiritual savior as historic and as influential as Jesus himself. By the 1920s he was attracting worldwide press attention and people flocked to his talks in the thousands. In 1922, Krishnamurti broke with the society and set out on a teaching mission of his own as a secular philosopher of spirituality. He ultimately had a career that spanned six decades, founded seven schools, published 50 books and encompassed thousands of talks. This extraordinary story is told for the first time by Roland Vernon in the full light of 20th-century attitudes in a narrative that is as compelling as any novel. (shrink)

IntroductionThe objectives of this study are to assess and compare differences in the intensity, frequency, and overall severity of moral distress among a diverse group of healthcare professionals.MethodsParticipants from within Baylor Health Care System completed an online seven-point Likert scale (range, 0 to 6) moral distress survey containing nine core clinical scenarios and additional scenarios specific to each participant’s discipline. Higher scores reflected greater intensity and/or frequency of moral distress.ResultsMore than 2,700 healthcare professionals responded to the survey (response rate 18.14 (...) percent); survey respondents represented multiple healthcare disciplines across a variety of settings in a single healthcare system. Intensity of moral distress was high in all disciplines, although the causes of highest intensity varied by discipline. Mean moral distress intensity for the nine core scenarios was higher among physicians than nurses, but the mean moral distress frequency was higher among nurses. Taking into account both intensity and frequency, the difference in mean moral distress score was statistically significant among the various disciplines. Using post hoc analysis, differences were greatest between nurses and therapists.ConclusionsMoral distress has previously been described as a phenomenon predominantly among nursing professionals. This first-of-its-kind multidisciplinary study of moral distress suggests the phenomenon is significant across multiple professional healthcare disciplines. Healthcare professionals should be sensitive to situations that create moral distress for colleagues from other disciplines. Policy makers and administrators should explore options to lessen moral distress and professional burnout that frequently accompanies it. (shrink)
