This article reviews models of the cerebellum and motor learning, from the landmark papers by Marr and Albus through those of the present time. The unique architecture of the cerebellar cortex is ideally suited for pattern recognition, but how is pattern recognition incorporated into motor control and learning systems? The present analysis begins with a discussion of exactly what the cerebellar cortex needs to regulate through its anatomically defined projections to premotor networks. Next, we examine various models showing how the (...) microcircuitry in the cerebellar cortex could be used to achieve its regulatory functions. Having thus defined what it is that Purkinje cells in the cerebellar cortex must learn, we then evaluate theories of motor learning. We examine current models of synaptic plasticity, credit assignment, and the generation of training information, indicating how they could function cooperatively to guide the processes of motor learning.

There exist two conjectures for constraint satisfaction problems of reducts of finitely bounded homogeneous structures: the first one states that tractability of the CSP of such a structure is, when the structure is a model-complete core, equivalent to its polymorphism clone satisfying a certain nontrivial linear identity modulo outer embeddings. The second conjecture, challenging the approach via model-complete cores by reflections, states that tractability is equivalent to the linear identities satisfied by its polymorphisms clone, together with the natural uniformity on (...) it, being nontrivial. We prove that the identities satisfied in the polymorphism clone of a structure allow for conclusions about the orbit growth of its automorphism group, and apply this to show that the two conjectures are equivalent. We contrast this with a counterexample showing that [Formula: see text]-categoricity alone is insufficient to imply the equivalence of the two conditions above in a model-complete core. Taking another approach, we then show how the Ramsey property of a homogeneous structure can be utilized for obtaining a similar equivalence under different conditions. We then prove that any polymorphism of sufficiently large arity which is totally symmetric modulo outer embeddings of a finitely bounded structure can be turned into a nontrivial system of linear identities, and obtain nontrivial linear identities for all tractable cases of reducts of the rational order, the random graph, and the random poset. Finally, we provide a new and short proof, in the language of monoids, of the theorem stating that every [Formula: see text]-categorical structure is homomorphically equivalent to a model-complete core.

Here, we report on a quasi-experimental study to explore the applicability and perceived benefits of the CRAFT program, which is based on mindfulness, yoga, positive psychology, and emotional intelligence, to improve higher education student musicians’ health and well-being during the lockdown. A subset of student musicians at a Higher Conservatory of Music in Spain followed the CRAFT program during the academic year 2019/2020, 1 h per week as part of their curriculum. Students enrolled in CRAFT-based elective subjects formed the CRAFT (...) program group, while other students represented the control group. The onset of the national lockdown elicited by the COVID-19 pandemic occurred halfway through the program, which was subsequently delivered in an online format. We administered an online survey to explore the effect that the exposure to the CRAFT program had in terms of how participants dealt with various health and well-being concerns arising from the COVID-19 lockdown. There was a significantly higher proportion of proactive participants in the CRAFT program group, 92%, than in the control group, 58%, in terms of implementing practices to improve their health and well-being during the lockdown. Additionally, significantly more participants acknowledged perceived benefits from their practices in the CRAFT program group, 78%, than in the control group, 52%. Among proactive participants, yoga/meditation was the most implemented in the CRAFT program group, followed by exercise, and other yoga/meditation practices, whereas in the control group, exercise and Alexander technique-based practices were the most applied. In the CRAFT program group, the highest rate of perceived benefits was from yoga/meditation CRAFT-based practices, 51%, followed by exercise, 32%, and other yoga/meditation practices, 27%, whereas in the control group, benefits were reported by 29% of exercising participants and 16% for those having practiced the Alexander technique. A similar pattern was observed when excluding participants with previous yoga/meditation experience. This study revealed how participants can independently apply learned skills from the CRAFT program in response to a naturally occurring life event of unprecedented global impact, suggesting that previous exposure to mindfulness and yoga is likely to have a beneficial effect on how young adults react towards exceptionally stressful conditions.

The concept ofmimēsiswas ‘shared by most authors, philosophers and educated audiences in the classical period, in antiquity as a whole, and even later’, although it has probably never been developed into a well-articulated theory. As far as we can judge from the extant evidence, the meaning of the expressions μίμησις and μιμέομαι differs from author to author and sometimes even from passage to passage. Ancient Greek views onmimēsishave often been discussed in modern scholarship, mainly within the field of history of (...) art, and it has been demonstrated repeatedly that the traditional English translation ‘imitation’ is not always appropriate for the ancient texts and that in many contexts it is rather misleading. In the following study I aim to focus on this concept as it was employed in the oldest Greek cosmological and philosophical theories. As a rule, the study of these theories is complicated by their fragmentary state of preservation and by their distortion through the specifically Platonic views that were dominant among the later doxographers. I shall suggest that the Platonizing tendency still prevalent today, which tends to translate and interpretmimēsisas ‘imitation’ or ‘copy’, should be carefully revised in the light of the Hippocratic evidence and specifically in view ofDe victu, probably the oldest authentic, non-fragmentary, and non-Platonic document attesting the concept ofmimēsis.

From the perspective of philosophy of science and technologies, we firstly attend to the issue of the role of nanotechnologies within the evolution of technologies. We recognize their utmost importance in the respect that they are technologies of life itself. We further explain that the nano-level is the domain of intersection of the rules of quantum physics and traditional Newtonian physics. This is our starting point from which we discuss the issue of conditions under which minimizing things also changes their (...) functional essence. We use the example of the Drexler vs. Smalley debate to demonstrate the paradigmatic incomparability of the two perspectives and the physical-chemical and engineering-related limits of nanotechnologies. We discuss to what extent are the dangers and ethical implications emerging from Drexler’s contemplations real, be it what he calls the “grey goo” problem or the issues of molecular production. We regard certain problems linked to synthetic biology as more serious. We conclude our text with the consideration that the human civilization should think of the possibilities of nanotechnologies in the development of life as an existential challenge. (shrink)

An examination of verbal hallucinations and thought insertion as examples of "alienated self-consciousness.".

This paper focuses on Aristotle’s methodology of science and its application to the study of the human soul. My aim is to contrast two significantly different methodological approaches and to formulate two pairs of premises that Aristotle employs in two clearly differentiated and independent fields of study, namely in his zoological works and in the works of practical philosophy. Acknowledging these principles, as I suggest, may shed a new light on the methodological difficulties that Aristotle indicates in the introductory chapters (...) of his De anima. (shrink)

The conceptualization of the vital force of living beings as a kind of breath and heat is at least as old as Homer. The assumptions that life and living things were somehow causally related to 'heat' and 'breath' would go on to inform much of ancient medicine and philosophy. This is the first volume to consider the relationship of the notions of heat, breath, and soul in ancient Greek philosophy and science from the Presocratics to Aristotle. Bringing together specialists both (...) on early Greek philosophy and on Aristotle, it brings an approach drawn from the history of science to the study of both fields. The chapters give fresh and detailed interpretations of the theory of soul in Heraclitus, Empedocles, Parmenides, Diogenes of Appolonia, and Democritus, as well as in the Hippocratic Corpus, Plato's Timaeus, and various works of Aristotle.

This is the first book to address the social organisation of modern yoga practice as a primary focus of investigation and to undertake a comparative analysis to explore why certain styles of yoga have successfully transcended geographical boundaries and endured over time, whilst others have dwindled and failed. Using fresh empirical data of the different ways in which posture practice was disseminated transnationally by Krishnamacharya, Sivananda and their leading disciples, the book provides an original perspective. The author draws upon extensive (...) archival research and numerous fieldwork interviews in India and the UK to consider how the field of yoga we experience today was shaped by historic decisions about how it was transmitted. The book examines the specific ways in which a small group of yogis organised their practices and practitioners to popularise their styles of yoga to mainstream audiences outside of India. It suggests that one of the most overlooked contributions has been that of Sivananda Saraswati (1887-1963) for whom this study finds his early example acted as a cornerstone for the growth of posture practice. Outlining how yoga practice is organised today on the world stage, how leading brands fit into the wider field of modern yoga practice and how historical developments led to a mainstream globalised practice, this book will be of interest to researchers in the field of Yoga Studies, Religious Studies, Hindu Studies, South Asian History, Sociology and Organisational Studies.

Ein geeignetes Mittel um die Philosophien aller Erdteile in das weltweite öffentliche Bewusstsein zu rücken ist die Schaffung einer Epocheneinteilung, die sich auf die globale Philosophiegeschichte bezieht. Der Band zeigt eine detaillierte Methodik auf, um genau solch eine Periodisierung zu verwirklichen.

The paper discusses the sharp semantic shifts of the Greek expressions psychê and sôma between the Archaic and Classical era. Concerning the documentary evidence of the medical, rhetorical and philosophical literature at the end of the 5th century BC, I argue that speculations on human health and disease attested in some of the Hippocratic treatises involved a specificnotionofthebody-souldistinctionandalsothatthisnotionprovides an important contrast to the definitionofphilosophyasatherapyofsoul.

Hume's Reception in Early America: Expanded Edition brings together the original American responses to one of Britain's greatest men of letters, David Hume. Now available as a single volume paperback, this new edition includes updated further readings suggestions and dozens of additional primary sources gathered together in a completely new concluding section. From complete pamphlets and booklets, to poems, reviews, and letters, to extracts from newspapers, religious magazines and literary and political journals, this book's contents come from a wide variety (...) of sources published in colonial America and the early United States between 1758 and 1850. As well as classics by Thomas Jefferson, John Adams and Alexander Hamilton, it contains scores of unknown and hard-to-locate items, many of which have not been reprinted since their original publication. These responses are divided into four parts covering Hume's Essays; his Philosophical Writings; his History of England; and his Character and Death. Each of those parts has a separate introductory essay, and every selection is introduced by a short headnote that sets the piece in its historical context and provides bibliographical references. Packed with new insights into Hume and American thought and culture, Hume's Reception in Early America reveals the relevance and impact of Hume on American political, philosophical, historical, religious, and aesthetic debates.

Biological evolution is a complex blend of ever changing structural stability, variability and emergence of new phe- notypes, niches, ecosystems. We wish to argue that the evo- lution of life marks the end of a physics world view of law entailed dynamics. Our considerations depend upon dis- cussing the variability of the very ”contexts of life”: the in- teractions between organisms, biological niches and ecosys- tems. These are ever changing, intrinsically indeterminate and even unprestatable: we do not know ahead of (...) time the ”niches” which constitute the boundary conditions on selec- tion. More generally, by the mathematical unprestatability of the ”phase space”, no laws of mo- tion can be formulated for evolution. We call this radical emergence, from life to life. The purpose of this paper is the integration of variation and diversity in a sound concep- tual frame and situate unpredictability at a novel theoretical level, that of the very phase space. Our argument will be carried on in close comparisons with physics and the mathematical constructions of phase spaces in that discipline. The role of symmetries as invariant preserving transformations will allow us to under- stand the nature of physical phase spaces and to stress the differences required for a sound biological theoretizing. In this frame, we discuss the novel notion of ”enablement”. Life lives in a web of enablement and radical emergence. This will restrict causal analyses to differential cases. Mutations or other causal differ- ences will allow us to stress that ”non conservation princi- ples” are at the core of evolution, in contrast to physical dynamics, largely based on conservation principles as sym- metries. Critical transitions, the main locus of symmetry changes in physics, will be discussed, and lead to ”extended criticality” as a conceptual frame for a better understanding of the living state of matter.
