Available in PDF, EPUB and Kindle. Book excerpt: Nous avons étudié en IRMf les bases neurales de l’imagerie mentale visuelle, à travers ses relations avec deux modes de représentation : l’un naturel, le langage, et l’autre artificiel, la réalité virtuelle. L’hémisphère gauche étant dominant pour le langage chez les droitiers, nous avons testé, dans une première étude, l’hypothèse d’une spécialisation hémisphérique gauche pour les images mentales ayant un contenu lexico-sémantique (objets) comparées à celles n’ayant aucune signification (non-objets). Cette expérience a révélé une activation d’un réseau occipito-temporo-frontal gauche plus importante dans l’imagerie mentale d’objets que dans celle de non-objets, confirmant ainsi l’hypothèse initiale. Une deuxième étude visait à déterminer si la nature réelle ou virtuelle de l’environnement appris modifie le substrat cérébral de la représentation topographique. Malgré l’observation de similitudes comportementales entre les modalités Réel et Virtuel, nous avons rapporté des différences au niveau neural, en particulier dans les régions sensori-motrices. La condition Réel a davantage recruté les aires prémotrices associées à l’activité locomotrice des sujets tandis que la condition Virtuel a davantage impliqué des régions frontales et pariétales latéralisées à gauche liées à l’utilisation d’un joystick, reflétant ainsi une trace neurale de la modalité d’apprentissage. Nos travaux de thèse montrent donc que le recrutement de l’hémisphère gauche en imagerie mentale serait modulé par la nature (signifiante vs non signifiante) des informations encodées ainsi que par la modalité (virtuelle vs réelle) dans laquelle ces informations ont été acquises

Available in PDF, EPUB and Kindle. Book excerpt: Nos travaux de thèse présentent l'influence de différents facteurs (nature de la tâche, contenu sémantique de l'image mentale, variabilité inter-individuelle) sur la nature des substrats neuraux impliqués dans des tâches d'imagerie mentale visuelle, et particulièrement sur la présence et l'absence d'activation de l'aire visuelle primaire (AVP). En Tomographie par Emission de Positon, nous avons montré que la réalisation d'une tâche d'imagerie mentale dans un environnement sonore bruyant induit l'activation d'un réseau d'aires attentionnelles, et de l'AVP, absente lors de la réalisation de la même tâche dans le silence. Nous avons également montré l'influence de la nature spatiale ou figurative de la tâche d'imagerie mentale sur l'activité de l'AVP. Enfin, en IRMf, nous avons observé un effet du caractère signifiant de l'image mentale, à l'origine d'un réseau d'activation latéralisé à gauche ainsi qu'une variabilité interindividuelle de l'activité de l'AVP.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction of the representation of self is based on the integration of information received by our different sensory modalities such as visual, auditory, tactile or proprioceptive information. The interaction between actions and movements and more recently social interactions and space are being explored at the behavioral level, but less so at the functional level and much more remains to be elucidated. In particular, it is important and fundamental to understand exactly which processes are involved in space representation and how, not only from a partial view focusing on specific cortical areas and single neuron processes but at the scale of the whole brain and the functional networks. The first axis of my thesis focuses on peripersonal space, that is the space that is closest to us, and represents one of the functional subspaces of spatial representation. We assume that it is the same regions that contribute to multisensory convergence, to the prediction of the consequences of a looming visual stimulus onto tactile processing and to the construction of peripersonal space. To test this hypothesis, we investigated the effect of the temporal and spatial predictive aspects of a dynamical looming visual stimulus onto tactile stimulus detection in humans (behavioral study) and non-human primates (fMRI study); the neural bases of near space and far space representations, in non-human primate (fMRI study). We highlight the involvement of a parieto-frontal network, essentially composed by the ventral intraparietal area VIP, the premotor area F4 as well as striate and extra-striate cortical regions, which are activated by these three different mechanisms. We propose that this network not only processes the trajectory of the looming object with respect to the body, but also anticipates its consequences onto the body and prepares protective actions in response to the looming stimulus. The second axis of my thesis focuses on characterizing the extent of plasticity in the visual representation of the adult brain (as opposed to the early stages around the critical developmental periods) and in particular, how the associated fine-grained changes in the visual cortex can be precisely quantified along multiple dimensions (anatomical, functional, pharmacological). Specifically, we have developed a set of high-resolution MRI methods to assess functional (high-resolution visual mapping fMRI, rs-MRI), pharmacological (GABA spectroscopy imaging) and structural (anatomical MRI, DTI) imaging to define reference measures against which to evaluate the changes induced by plasticity at different times after its induction, through a longitudinal study performed in the same animals. Some of these methods need to be more refined but they show that they are really promising to study plasticity in nonhuman primate. On the whole, this present doctoral research allows to make a functional link between human fMRI studies and monkey single cell recording studies and provides new strategies and explorations to perform on the spatial representation field both in humans and non-human primates.

Download or read book Alienation and Freedom written by Frantz Fanon and published by Bloomsbury Publishing. This book was released on 2018-04-19 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of The Wretched of the Earth in 1961, Fanon's work has been deeply significant for generations of intellectuals and activists from the 60s to the present day. Alienation and Freedom collects together unpublished works comprising around half of his entire output – which were previously inaccessible or thought to be lost. This book introduces audiences to a new Fanon, a more personal Fanon and one whose literary and psychiatric works, in particular, take centre stage. These writings provide new depth and complexity to our understanding of Fanon's entire oeuvre revealing more of his powerful thinking about identity, race and activism which remain remarkably prescient. Shedding new light on the work of a major 20th-century philosopher, this disruptive and moving work will shape how we look at the world.

Download or read book Mind and Its Evolution written by Allan Paivio and published by Psychology Press. This book was released on 2014-01-14 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book updates the Dual Coding Theory of mind (DCT), a theory of modern human cognition consisting of separate but interconnected nonverbal and verbal systems. Allan Paivio, a leading scholar in cognitive psychology, presents this masterwork as new findings in psychological research on memory, thought, language, and other core areas have flourished, as have pioneering developments in the cognitive neurosciences. Mind and Its Evolution provides a thorough exploration into how these adaptive nonverbal and verbal systems might have evolved, as well as a careful comparison of DCT with contrasting "single-code" cognitive theories. Divided into four parts, this text begins with a general, systematic theory of modern human cognition as the reference model for interpreting the cognitive abilities of evolutionary ancestors. The first half of the book discusses mind as it is; the second half addresses how it came to be that way. Each half is subdivided into two parts defined by thematic chapters. Mind and Its Evolution concludes with evidence-based suggestions about nourishing mental growth through applications of DCT in education, psychotherapy, and health. This volume will appeal to cognitive and evolutionary psychologists, as well as students in the areas of memory, language, cognition, and mind evolution specialists in psychology, philosophy, and other disciplines.

Download or read book Frontal Lobe written by Andrea E. Cavanna and published by Nova Biomedical Books. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frontal lobes, which constitute about one-third of the entire cerebral cortex, have long fascinated scientific explorers of human behaviour. There are multiple reasons for this: the frontal lobes are the most recently evolved parts of the brain of Homo sapiens and can be viewed as the executive centre of the entire nervous system, subserving the key function of goal-oriented behaviour and reconciling internal emotional states with the demands of the external environment. This book presents some of the latest research on the structure and functional role of the frontal lobes, as revealed by both physiological and pathological studies. This timely and comprehensive volume exemplifies that only a truly multidisciplinary and collaborative effort from the allied disciplines of neuroanatomy, neurophysiology, neuropathology, neuroimaging, neuropsychology and neuropsychiatry will result in a better understanding of the wide-reaching implications of frontal lobe dysfunction.

Download or read book Language Play Language Learning written by Guy Cook and published by Oxford University Press. This book was released on 2000-02-03 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has two related purposes. The first is to demonstrate the extent and importance of language play in human life; the second is to draw out the implications for applied linguistics and language teaching. Language play should not be thought of as a trivial or peripheral activity, but as central to human thought and culture, to learning, creativity, and intellectual enquiry. It fulfils a major function of language, underpinning the human capacity to adapt: as individuals, as societies, and as a species.

Download or read book Treatise on Musical Objects written by Pierre Schaeffer and published by Univ of California Press. This book was released on 2017-07-25 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Treatise on Musical Objects is regarded as Pierre Schaeffer’s most important work on music and its relationship with technology. Schaeffer expands his earlier research in musique concrète to suggest a methodology of working with sounds based on his experiences in radio broadcasting and the recording studio. Drawing on acoustics, physics, and physiology, but also on philosophy and the relationship between subject and object, Schaeffer’s essay summarizes his theoretical and practical work in music composition. Translators Christine North and John Dack present an important book in the history of ideas in Europe that will resonate far beyond electroacoustic music.

Book excerpt: "A whimsical, surrealistic excursion into the modern scientific mind." --The New Yorker One of DeLillo's first novels, Ratner's Star follows Billy, the genius adolescent, who is recruited to live in obscurity, underground, as he tries to help a panel of estranged, demented, and yet lovable scientists communicate with beings from outer space. It is a mix of quirky humor, science, mathematical theories, as well as the complex emotional distance and sadness people feel. Ratner's Star demonstrates both the thematic and prosaic muscularity that typifies DeLillo's later and more recent works, like The Names (which is also available in Vintage Contemporaries). "His most spectacularly inventive novel." --The New York Times
