An increasing number of research teams are investigating the efficacy of brain-computer interface (BCI)-mediated interventions for promoting motor recovery following stroke. A growing body of evidence suggests that of the various BCI designs, most effective are those that deliver functional electrical stimulation (FES) of upper extremity (UE) muscles contingent on movement intent. More specifically, BCI-FES interventions utilize algorithms that isolate motor signals—user-generated intent-to-move neural activity recorded from cerebral cortical motor areas—to drive electrical stimulation of individual muscles or muscle synergies. BCI-FES (...) interventions aim to recover sensorimotor function of an impaired extremity by facilitating and/or inducing long-term motor learning-related neuroplastic changes in appropriate control circuitry. We developed a non-invasive, electroencephalogram (EEG)-based BCI-FES system that delivers closed-loop neural activity-triggered electrical stimulation of targeted distal muscles while providing the user with multimodal sensory feedback. This BCI-FES system consists of three components: (1) EEG acquisition and signal processing to extract real-time volitional and task-dependent neural command signals from cerebral cortical motor areas, (2) FES of muscles of the impaired hand contingent on the motor cortical neural command signals, and (3) multimodal sensory feedback associated with performance of the behavioral task, including visual information, linked activation of somatosensory afferents through intact sensorimotor circuits, and electro-tactile stimulation of the tongue. In this report, we describe device parameters and intervention protocols of our BCI-FES system which, combined with standard physical rehabilitation approaches, has proven efficacious in treating UE motor impairment in stroke survivors, regardless of level of impairment and chronicity.

Henricus Regius ou Henri LeRoy, outrora amigo e divulgador da filosofia de Descartes, agora escrevendo como adversário de seu antigo mestre, publica em Utrecht um panfleto anônimo sobre a natureza da mente humana. No intuito de evitar que as teses apresentadas por seu ex-discípulo fossem tomadas como suas, Descartes decide, então, refutar as opiniões defendidas no panfleto de Regius. É precisamente o texto produzido por Descartes nessa ocasião que é traduzido a seguir. Esse texto, aparentemente impresso sem o consentimento (...) de seu autor em dezembro de 1647, marca o ponto final da relação entre o filósofo francês e o professor de medicina. O texto latino aqui traduzido foi extraído da edição realizada por Charles Adam e Paul Tannery das Oeuvres complètes de Descartes, Paris, Vrin, tomo VIII, pp. 341-369. (shrink)

مداخلة مترجمة عن الفرنسية للفيلسوف الفرنسي جيل دولوز.

This work aims to defines the question Is there a human nature? It argues that we know our nature only when it is recognized by our culture and that the liberal democratic idea of the state both celebrates and threatens the notion of fundamental human equality.

Noted psychologist and philosopher develops his own brand of pragmatism, based on theories of C. S. Peirce. Emphasis on "radical empiricism," versus the transcendental and rationalist tradition. One of the most important books in American philosophy. Note.

If Christian theology is that enterprise whose essential purpose is to understand the faith of the Christian Church, then it must approach that faith from the perspective not only of its transcendent source, but also as a human achievement, a creative interpretation of those events in which transcendent reality discloses itself for appropriation. Few theologians would deny that theology has to do primarily with the ways in which ultimate reality becomes manifest in human beings' faithful responses, in belief and trust, (...) to its self-disclosures, preparatory and decisive. But the implications of such a view are not always confronted straightforwardly, especially for the suitable normative principles by which theology must assess the adequacy of the church's expressions of its faith. This essay seeks to probe how an account of the Christian faith could proceed whose norm derives not from the revelatory source of faith but from the dynamic of human creativity within which alone faith's source, in being interpreted, becomes clear, cogent, and decisive for conscious existence.

Aboriginal peoples are forever explaining themselves to non-Aboriginal people: telling their stories, explaining their beliefs and ceremonies, and introducing ideas that have never crossed the non-Aboriginal mind. Western knowledge operates from a linear, singular view; it views the world from order beneath chaos; it is very noun oriented; knowledge is about oneself in relation to everything else in a relativistic sense. Aboriginal knowledge has a very different “coming to know.” It is holistic and cyclical; it views the world from chaos (...) underneath order; its languages are process and action oriented. Knowledge is about participation in and with the natural world. (shrink)

An empirical exploration of the effects on legislative structure, distribution of influence, power, and decision outcomes, of recent changes in the Congress and state legislatures. The book focuses on changes in rules, parties, and committees and the impact or lack of impact of these changes on subsequent activity. Originally published in 1978 by D.C. Heath and Company. Co-published with the Policy Studies Organization.

This first volume contains discussions of the brain, methods for analyzing behavior, thought, consciousness, attention, association, time, and memory.

With a new foreword by Jonathan Lear 'Remarkably lively and enjoyable…It is a very rich book, containing excellent descriptions of a variety of moral theories, and innumerable and often witty observations on topics encountered on the way.' -_ Times Literary Supplement_ Bernard Williams was one of the greatest philosophers of his generation. Ethics and the Limits of Philosophy is not only widely acknowledged to be his most important book, but also hailed a contemporary classic of moral philosophy. Drawing on (...) the ideas of the Greek philosophers, Williams reorients ethics away from a preoccupation with universal moral theories towards ‘truth, truthfulness and the meaning of an individual life’. He explores and reflects upon the most difficult problems in contemporary philosophy and identifies new ideas about central issues such as relativism, objectivity and the possibility of ethical knowledge. This edition also includes a commentary on the text by A.W.Moore. At the time of his death in 2003, Bernard Williams was hailed by the Times as 'the outstanding moral philosopher of his age.' He taught at the Universities of Cambridge, Berkeley and Oxford and is the author of many influential books, including _Morality; Descartes: The Project of Pure Enquiry_ and _Truth and Truthfulness_.

Liberal thinkers of the eighteenth and nineteenth centuries were alert to the political costs and human cruelties involved in European colonialism, but they also thought that European expansion held out progressive possibilities. In Progress, Pluralism, and Politics David Williams examines the colonial and anti-colonial arguments of Adam Smith, Immanuel Kant, Jeremy Bentham, and L.T. Hobhouse. Williams locates their ambivalent attitude towards European conquest and colonial rule in a set of tensions between the impact of colonialism on European states, (...) the possibilities of progress in distant and diverse places, and the relationship between universalism and cultural pluralism. In so doing he reveals some of the central ambiguities that characterize the ways that liberal thought has dealt with the reality of an illiberal world. Of particular importance are appeals to various forms of universal history, attempts to mediate between the claims of identity and the reality of difference, and the different ways of thinking about the achievement of liberal goods in other places. Pointing to key elements in still ongoing debates within liberal states about how they should relate to illiberal places, Progress, Pluralism, and Politics enriches the discussion on political thought and the relationship between liberalism and colonialism.

A representationalist-friendly introduction to representationalism which covers a number of central problems and objections.

The Gifford Lectures were established in 1885 at the universities of St Andrews, Glasgow, Aberdeen and Edinburgh to promote the discussion of 'Natural Theology in the widest sense of the term - in other words, the knowledge of God', and some of the world's most influential thinkers have delivered them. The 1901–2 lectures given in Edinburgh by American philosopher William James are considered by many to be the greatest in the series. The lectures were published in book form in 1902 (...) and have been reprinted many times. James, who was educated in the United States and Europe, and spent much of his career teaching philosophy at Harvard, was very influential in the development of modern psychology, and in these twenty lectures he explores the personal experience of religion. Some of the topics include religion and neurology, 'the sick soul', saintliness, and mysticism. (shrink)

For this 1897 publication, the American philosopher William James brought together ten essays, some of which were originally talks given to Ivy League societies. Accessible to a broader audience, these non-technical essays illustrate the author's pragmatic approach to belief and morality, arguing for faith and action in spite of uncertainty. James thought his audiences suffered 'paralysis of their native capacity for faith' while awaiting scientific grounds for belief. His response consisted in an attitude of 'radical empiricism', which deals practically rather (...) than ideologically with real-world phenomena. When facing a 'momentous' decision about belief, he says, we both can and must choose the best hypothesis. The first four essays apply this principle to religious faith, and the rest explore the pragmatic approach to such topics as determinism, ethics and individual achievement. James developed his ideas further in The Varieties of Religious Experience and Pragmatism, both of which are reissued in this series. (shrink)

: In 1998, researchers discovered that embryonic stem cells could be derived from early human embryos. This discovery has raised a series of ethical and public-policy questions that are now being confronted by multiple international organizations, nations, cultures, and religious traditions. This essay surveys policies for human embryonic stem cell research in four regions of the world, reports on the recent debate at the United Nations about one type of such research, and reviews the positions that various religious traditions have (...) adopted regarding this novel type of research. In several instances the religious traditions seem to have influenced the public-policy debates. (shrink)

Anselm's two ‘ontological’ arguments rest upon three fundamental assertions: The idea of God is the idea of a being than which nothing more perfect is conceivable. Whatever exists in the understanding and outside the understanding is more perfect than whatever exists in the understanding alone. Whatever cannot be conceived not to exist is more perfect than whatever can be conceived not to exist.
