Bidirectional deep brain stimulation (DBS) platforms have enabled a surge in hours of recordings in naturalistic environments, allowing further insight into neurological and psychiatric disease states. However, high amplitude, high frequency stimulation generates artifacts that contaminate neural signals and hinder our ability to interpret the data. This is especially true in psychiatric disorders, for which high amplitude stimulation is commonly applied to deep brain structures where the native neural activity is miniscule in comparison. Here, we characterized artifact sources in recordings (...) from a bidirectional DBS platform, the Medtronic Summit RC + S, with the goal of optimizing recording configurations to improve signal to noise ratio (SNR). Data were collected from three subjects in a clinical trial of DBS for obsessive-compulsive disorder. Stimulation was provided bilaterally to the ventral capsule/ventral striatum (VC/VS) using two independent implantable neurostimulators. We first manipulated DBS amplitude within safe limits (2–5.3 mA) to characterize the impact of stimulation artifacts on neural recordings. We found that high amplitude stimulation produces slew overflow, defined as exceeding the rate of change that the analog to digital converter can accurately measure. Overflow led to expanded spectral distortion of the stimulation artifact, with a six fold increase in the bandwidth of the 150.6 Hz stimulation artifact from 147–153 to 140–180 Hz. By increasing sense blank values during high amplitude stimulation, we reduced overflow by as much as 30% and improved artifact distortion, reducing the bandwidth from 140–180 Hz artifact to 147–153 Hz. We also identified artifacts that shifted in frequency through modulation of telemetry parameters. We found that telemetry ratio changes led to predictable shifts in the center-frequencies of the associated artifacts, allowing us to proactively shift the artifacts outside of our frequency range of interest. Overall, the artifact characterization methods and results described here enable increased data interpretability and unconstrained biomarker exploration using data collected from bidirectional DBS devices.

Recent advances in wireless data transmission technology have the potential to revolutionize clinical neuroscience. Today sensing-capable electrical stimulators, known as “bidirectional devices”, are used to acquire chronic brain activity from humans in natural environments. However, with wireless transmission come potential failures in data transmission, and not all available devices correctly account for missing data or provide precise timing for when data losses occur. Our inability to precisely reconstruct time-domain neural signals makes it difficult to apply subsequent neural signal processing techniques (...) and analyses. Here, our goal was to accurately reconstruct time-domain neural signals impacted by data loss during wireless transmission. Towards this end, we developed a method termed Periodic Estimation of Lost Packets. PELP leverages the highly periodic nature of stimulation artifacts to precisely determine when data losses occur. Using simulated stimulation waveforms added to human EEG data, we show that PELP is robust to a range of stimulation waveforms and noise characteristics. Then, we applied PELP to local field potential recordings collected using an implantable, bidirectional DBS platform operating at various telemetry bandwidths. By effectively accounting for the timing of missing data, PELP enables the analysis of neural time series data collected via wireless transmission—a prerequisite for better understanding the brain-behavior relationships underlying neurological and psychiatric disorders.

The exposition of Foucault’s archeological method seeks to show its advantages in comparison to more traditional forms of analysis.

The object of this article is to show some convergences between the thought of Hannah Arendt and of Michel Foucault. My thesis is that both authors aims a thought of the openess and not determined, a political alternative that goes beyong the party politics and aims to recover the public space. Politics as activity of creation and experimentation. The political theory of Hannah Arendt represents a tentative to think the event, to affront the contingency and to deny the traditional images (...) and metaphors offered to imagine the political. It is a will to act, to transgress and overcome the limits.O objetivo deste artigo é mostrar algumas convergências entre o pensamento de Hannah Arendt e o de Foucault.

Política como atividade de criação e de experimentação. A teoria política de Hannah Arendt representa uma tentativa de pensar o acontecimento, de afrontar a contingência, de recusar as imagens e metáforas tradicionais oferecidas para imaginar o político, como uma vontade de agir, de transgredir e superar os limites.

This essay traces the genealogy and evolution of the category of the subject as it developed in the thought of Louis Althusser, Michel Foucault, and Alain Badiou. As will be seen, within the fruitful and complementary dialogue about the subject and subjectivity formation among these three French thinkers, there are major discrepancies in their approaches, from Althusser’s seemingly passive view of the subject as a victim of state oppression, to Foucault’s one, embedded in power but with the capacity of resistance, (...) and, finally, to Badiou’s understanding, in his book Théorie du sujet (Theory of the Subject, 1982), of the subject as the one who courageously takes risks to put into practice the truth brought about by the event in order to radically transform the present situation.

Iván Ortega Rodríguez livre une contribution où M. Henry est mis en confrontation avec Patočka, notamment sur la corrélation entre la vie et le monde, autrement dit sur l’« a priori de corrélation ». Comme le rappelle l’auteur de cette étude, tant Patočka que M. Henry adoptent cette corrélation a priori comme point de départ, et donc eu égard aux questions portant respectivement sur l’apparaître, sur ce qui apparaît et sur cette vie subjective qui semble devoir accompagner toute donation. (...) Aussi Iván Ortega Rodríguez soutient-il que tout semble se jouer entre M. Henry et Patočka dans leur conception de l’apparaître. Autant la donation henryenne nous invite à nous singulariser dans notre expérience selon le pathos de la vie auto-affective, autant elle nous invite chez Patočka à sortir hors de nous-mêmes selon la priorité accordée à l’aspect de « champ » que nous trouvons dans le se-montrer, là où se place tout ce qui est donné.

In this paper, relying mainly on his "Preface for Germans" I describe Ortega's complaints about Husserl's transcendental reduction, his own "anti-idealistic" approach to phenomenology, and his alternative version of the reduction, a reduction to life. Similarities with the work of Michel Henry are noted, but not explored in detail. Mention is made of Graham Harmon's interpretation of Ortega in "Guerrilla Metaphysics," but only to set up my interpretation of Ortega.

Echoing Richard Rorty’s earlier Consequences of Pragmatism, this collection begins with an essay on “Phenomenology in America: 1964-1984,” and concludes with a “Response to Rorty, or Is Phenomenology Edifying?” In between, the differences in the philosophical habits and practice of Anglo-American and Euro-American philosophers are examined and a reformulated, non-foundational phenomenology is sketched as a new direction responsive to the current situation in American philosophy. Don Ihde considers perception, technics, and contemporary Continental thinkers such as Jacques Derrida, Hans Georg Gadamer, (...) Michel Foucault, Ortega y Gassett, and Paul Ricoeur. (shrink)

Ortega y Gasset’s old lament that no one had so far attempted a rigorous phenomenology of pain no longer holds since the appearance of Christian Grüny’s recent monograph Zerstörte Erfahrung. Eine Phänomenologie des Schmerzes. Grüny argues for the use of phenomenological categories from Merleau-Ponty in order to understand physical pain as a “blocked escape-movement” , concluding that corporeal suffering makes impossible both a clean distinction and a pure identification between the lived body and the physical body that I am. (...) In my paper, I would like to suggest some improvements to Grüny’s approach through the utilization of the category of self-affection, as the material phenomenology of Michel Henry has developed it. In addition to the radical immanence in which hyle, noesis, and noema are unified into a “carnal cogito,” however, I argue that it is necessary to describe the painful self-affection not only in terms of any sensitive excess whatever , as Grüny posits, but also in terms of a mutation of the sensitive excess into the intra-tactile sphere of sensibility. Thus I endorse the Husserlian insight that makes tactility the primordial structure of sensibility. (shrink)

El presente trabajo pretende explorar la actualidad del pensamiento de Baltasar Gracián a propósito del sujeto y la cultura a partir de las filosofías de Michel Foucault y José Ortega y Gasset. En primer lugar, se analizará la caracterización del sujeto graciano desde el prisma de La hermenéutica del sujeto como representante de una modernidad alternativa en que la separación entre la filosofía y la espiritualidad no llega a consumarse. En segundo lugar, se elucidará la ambivalencia de Gracián a (...) propósito del artificio en relación con la crítica de la cultura y la técnica, tomando como referencia la crisis de la capacidad de desear planteada en Meditación de la técnica como causa de la crisis cultural de la época. Ambas incursiones tratarán de poner de manifiesto la relevancia del pensamiento de Gracián en la época contemporánea, caracterizada frecuentemente como un Neobarroco. (shrink)

The human species is more reliant on cultural adaptation than any other species, but it is unclear how observational learning can give rise to the faithful transmission of cultural adaptations. One possibility is that teaching facilitates accurate social transmission by narrowing the range of inferences that learners make. However, there is wide disagreement about how to define teaching, and how to interpret the empirical evidence for teaching across cultures and species. In this article I argue that disputes about the nature (...) and prevalence of teaching across human societies and nonhuman animals are based on a number of deep-rooted theoretical differences between fields, as well as on important differences in how teaching is defined. To reconcile these disparate bodies of research, I review the three major approaches to the study of teaching – mentalistic, culture-based, and functionalist – and outline the research questions about teaching that each addresses. I then argue for a new, integrated framework that differentiates between teaching types according to the specific adaptive problems that each type solves, and apply this framework to restructure current empirical evidence on teaching in humans and nonhuman animals. This integrative framework generates novel insights, with broad implications for the study of the evolution of teaching, including the roles of cognitive constraints and cooperative dilemmas in how and when teaching evolves. Finally, I propose an explanation for why some types of teaching are uniquely human, and discuss new directions for research motivated by this framework. (shrink)

What is given to us in conscious experience? The Given is an attempt to answer this question and in this way contribute to a general theory of mental content. The content of conscious experience is understood to be absolutely everything that is given to one, experientially, in the having of an experience. Michelle Montague focuses on the analysis of conscious perception, conscious emotion, and conscious thought, and deploys three fundamental notions in addition to the fundamental notion of content: the (...) notions of intentionality, phenomenology, and consciousness. She argues that all experience essentially involves all four things, and that the key to an adequate general theory of what is given in experience lies in giving a correct specification of the nature of these four things and the relations between them.

My concern in this paper is with the intentionality of emotions. Desires and cognitions are the traditional paradigm cases of intentional attitudes, and one very direct approach to the question of the intentionality of emotions is to treat it as sui generis—as on a par with the intentionality of desires and cognitions but in no way reducible to it. A more common approach seeks to reduce the intentionality of emotions to the intentionality of familiar intentional attitudes like desires and cognitions. (...) In this paper, I argue for the sui generis approach. (shrink)

Attachment theory, postulated by John Bowlby in collaboration with psychologists Mary Ainsworth and Harry Harlow, has been the subject of much discussion about its nature. The author considers it a psychoanalytical theory, but his peers in psychoanalysis at the time rejected this idea and offered criticism of his concepts, suggesting that they were not in alignment with the principles of psychoanalysis. At the same time, collaborators Mary Ainsworth and Harry Harlow have repeatedly questioned the necessity of Bowlby’s choice of psychoanalysis (...) as a basis for attachment theory, suggesting that it may not be the most appropriate approach. Lately, attachment theory has been used in many psychology courses and articles, without so much as a single mention to its psychoanalytical nature. This article presents a research proposal for an investigation of the nature of attachment theory on a conceptual level. It poses the question of whether the concepts used as a basis for attachment theory are consistent with psychoanalysis. (shrink)

My research explores Maya perspectives on neo-traditional farming as a source of metabolic health and resilience to the global epidemic of type-two diabetes. This article is based on long-term ethnographic research and interviews in Maya Mountains Reservation communities in southern Belize, an area with low diabetes prevalence relative to national and global populations. Research participants see lower rates of diabetes in the MMR as the result of neo-traditional peasant and subsistence farming on ancestral lands. Good metabolic health represents the embodiment (...) of food systems that routinize healthy material and social relationships to the landscape. This research suggests that diabetes is endemic to modern food systems and proposes neo-traditional food ways as a societal antidote to nutritional disease. My research demonstrates and responds to a need for further disaggregated data on diabetes prevalence in Indigenous communities, contributes to the social scientific literature on the importance of small-scale agricultural models for community health, and provides a case study of success in diabetes prevention. I engage Maya perspectives with anthropological literature on embodiment and small-scale agriculture to suggest neo-traditional food ways as healthier alternatives to capitalist agricultural development.

The long-standing debate between cognitive and feeling theories of emotion stems, in part, from the assumption that cognition and thought are abstract, intellectual, disembodied processes, and that bodily feelings are non-intentional and have no representational content. Working with this assumption has led many emotions theorists to neglect the way in which emotions are simultaneously bodily and cognitive-evaluative. Even hybrid theories, such as those set forth by Prinz and Barlassina and Newen, fail to account fully for how the cognitive and bodily (...) elements of emotion are integrated. As a result, such accounts are unable to provide an adequate characterization of the intentionality or phenomenology of emotions. I will argue that an enactive account of emotions, one which characterizes them as a way of engaging with and making sense of one’s surroundings, can help us to overcome this false dichotomy between cognitive and body elements. What I call ‘ affective framing’ is at the core of emotional experience. It is the way in which we engage with and appraise our surroundings in and through bodily feelings of caring, so that the bodily and cognitive elements of emotion necessarily are fused. The notion of affective framing not only helps to clarify the relationship between bodily and cognitive elements of emotion, but also offers a useful way to make sense of both the intentional directedness and phenomenal character of emotional experience.

This article presents an overview for clinician investigators on the concepts of decision-making capacity and vulnerability as related to human subjects research. Tools for capacity assessment and unacknowledged sources of vulnerability are discussed, and the practical gaps in current informed consent requirements related to impaired capacity and potential vulnerability are described. Options are suggested for research discussions when full regulatory consent is not possible and an exception from informed consent does not apply.

The issue of what is proper to nature, or life itself, is central to critical accounts of biomedicine and its complex interrelations with social, political and economic forces. These engagements, namely biopolitical accounts of medical practices and ethical-political critiques of biomedical discourse, grapple with the indistinction between the political and biological that biomedicine enacts. Making a significant contribution to both literatures, Ed Cohen’s A Body Worth Defending argues that the emergence of the concept of biological immunity signals the entry of (...) politics into life itself and, as such, constitutes a concrete example of biopolitics. This article examines Cohen’s account of how the political becomes biological, and the view of life it assumes. Seeking to open up the question of biology, it draws on the work of Georges Canguilhem, and New Materialist accounts of matter–meaning entanglement, to offer a reading of knowledge and life, or politics and biology, as ontologically entangled.

According to some formulations of the thesis of revelation, knowledge about the essences of phenomenal properties is available through introspection. But this claim may seem doubtful given relevant limits of introspection. This paper articulates the worry and sketches responses to address it.

This rich and varied collection of essays addresses some of the most fundamental human questions through the lenses of philosophy, literature, religion, politics, and theology. Peter Augustine Lawler and Dale McConkey have fashioned an interdisciplinary consideration of such perennial and enduring issues as the relationship between nature and history, nature and grace, reason and revelation, classical philosophy and Christianity, modernity and postmodernity, repentance and self-limitation, and philosophy and politics.

Beginning with the view that human consciousness is essentially embodied and that the way we consciously experience the world is structured by our bodily dynamics and surroundings, the book argues that emotions are a fundamental manifestation of our embodiment, and play a crucial role in self-consciousness, moral evaluation, and social cognition.

After decades of neglect, positive emotion is now the focus of a rich, diverse, and rapidly growing field. Basic research has advanced understanding of positive emotions’ neural mechanisms, nonverbal expression, and implications for cognition and motivation, with increasing appreciation of positive emotion differentiation, as well as cultural and contextual moderators of positive emotions’ effects. Much research has also addressed ways positive emotions can be leveraged to improve the human condition, and the mechanisms by which interventions have beneficial effects. As always, (...) new knowledge raises more questions, and we still have a long way to go before the promise of this field can be fully realized. This comment reviews major developments in positive emotion science and offers recommendations for the future. (shrink)

Building on contemporary research in embodied cognition, enactivism, and the extended mind, this book explores how social institutions in contemporary neoliberal nation-states systematically affect our thoughts, feelings, and agency. Human beings are, necessarily, social animals who create and belong to social institutions. But social institutions take on a life of their own, and literally shape the minds of all those who belong to them, for better or worse, usually without their being self-consciously aware of it. Indeed, in contemporary neoliberal societies, (...) it is generally for the worse. In The Mind-Body Politic, Michelle Maiese and Robert Hanna work out a new critique of contemporary social institutions by deploying the special standpoint of the philosophy of mind—in particular, the special standpoint of the philosophy of what they call essentially embodied minds—and make a set of concrete, positive proposals for radically changing both these social institutions and also our essentially embodied lives for the better.

Despite contemporary moral philosophers' renewed attention to the moral significance of emotions, the attitudinal repertoire with which they equip the mature moral agent remains stunted. One attitude moral philosophers neglect (if not disown) is contempt. While acknowledging the nastiness of contempt, I here correct the neglect by providing an account of the moral psychology of contempt. In the process, I defend the moral propriety of certain tokens of properly person-focused contempt against some prominent objections -- among them, objections stemming from (...) Kantian worries that contempt is incompatible with the respect we owe to persons as such. (shrink)

Michelle Kosch examines the conceptions of free will and the foundations of ethics in the work of Kant, Schelling, and Kierkegaard. She seeks to understand the history of German idealism better by looking at it through the lens of these issues, and to understand Kierkegaard better by placing his thought in this context. Kosch argues for a new interpretation of Kierkegaard's theory of agency, that Schelling was a major influence and Kant a major target of criticism, and that both (...) the theory and the criticisms are highly relevant to contemporary debates.

Philosophical suspicions about the place of shame in the psychology of the mature moral agent are in tension with the commonplace assumption that to call a person shameless purports to mark a fault, arguably a moral fault. I shift philosophical suspicions away from shame and toward its absence in the shameless by focusing attention on phenomena of shamelessness. In redirecting our attention, I clarify the nature of the failing to which ascriptions of shamelessness might refer and defend the thought that, (...) as an evasion of moral self-censure, shamelessness can be morally pernicious. Far from foregoing shame, I conclude, we should be mindful of its moral importance and unapologetic in its defense. (shrink)

Spatial aspects of words are associated with their canonical locations in the real world. Yet little research has tested whether spatial associations denoted in language comprehension generalize to their corresponding images. We directly tested the spatial aspects of mental imagery in picture and word processing (Experiment 1). We also tested whether spatial representations of motion words produce similar perceptual-interference effects as demonstrated by object words (Experiment 2). Findings revealed that words denoting an upward spatial location produced slower responses to targets (...) appearing at the top of the display, whereas words denoting a downward spatial location produced slower responses to targets appearing at the bottom of the display. Perceptual-interference effects did not obtain for pictures or for words lacking a spatial relation. These findings provide greater empirical support for the perceptual-symbols system theory (Barsalou, 1999, 2008). (shrink)

'Propositionalism' is the widely held view that all intentional mental relations-all intentional attitudes-are relations to propositions or something proposition-like. Paradigmatically, to think about the mountain is ipso facto to think that it is F, for some predicate 'F'. It seems, however, many intentional attitudes are not relations to propositions at all: Mary contemplates Jonah, adores New York, misses Athens, mourns her brother. I argue, following Brentano, Husserl, Church and Montague among others, that the way things seem is the way they (...) are, and that propositionalism must be abandoned. (shrink)

From farmers’ markets to primetime television cooking shows, notions of ‘knowing where our food comes from’ and ‘reconnecting’ with the sources of our food are now central to a range of contemporary cultural movements and popular media texts. While these ideas have primarily been mobilized by those with activist commitments to ethical and sustainable food production, they are also increasingly appearing in the media and marketing strategies of large agribusiness and retailing corporations, including those of the major Australian supermarkets. This (...) paper explores some of the techniques currently used by major supermarkets to respond to criticisms about their food ethics, market control and relationship with producers. Using a case study of Australian supermarket Coles and its integration of its ‘Helping Australia Grow’ campaign into reality television cooking show, My Kitchen Rules, it will consider the textual practices of, and social media response to, Coles’ sponsorship and integrated advertising strategies of putting a ‘face’ to the farmers who produce the products found on supermarket shelves. By emphasizing to Coles customers that they, too, can ‘know where their food comes from’ and that their purchasing decisions support individual farmers and family farms rather than large conglomerates, these strategies help to locate Coles within a network of meanings that seek to both shift and contest negative perceptions of the supermarket chain’s corporate practices and food politics in ways that potentially complicate the activist discourses from which they draw.

International documents on ethical conduct in clinical research have in common the principle that potential harms to research participants must be proportional to anticipated benefits. The anticipated benefits that can justify human research consist of direct benefits to the research participant, and societal benefits, also called social value. In first-in-human research, no direct benefits are expected and the benefit component of the risks-benefit assessment thus merely exists in social value. The concept social value is ambiguous by nature and is used (...) in numerous ways in the research ethics literature. Because social value justifies involving human participants, especially in early human trials, this is problematic. (shrink)

Arts and Humanities in Higher Education, Volume 21, Issue 1, Page 3-20, February 2022. As graduate labour market conditions have become increasingly challenging, higher education institutions have intensified their focus on ‘employability’ via strategies such as work placements. Focusing on work placements in the media and creative industries, this article identifies and analyses three key discourses that animate the pedagogical literature in these sectors: work placements as facilitating a ‘smooth transition’ to the labour market; work placements as a place in (...) which inequalities in the labour market are produced; and work placements as a space for fostering resilience and adaptation to labour market precarity. The article argues that critiques of inequalities based on race, class or gender are marked by a transformative impulse that is largely absent in critiques of those based on worker precarity. This highlights a need to adopt pedagogies that similarly unnaturalise the economic conditions of neoliberal capitalism to discursively construct work in new, more socially just, ways. (shrink)
