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.

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

Download or read book Neurobiology of Umwelt written by Alain Berthoz and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the 20th century, German biologist Jakob von Uexküll created the concept of "Umwelt" to denote the environment as experienced by a subject. This concept of environment differs from the idea of passive surroundings and is defined not just by physical surroundings, but is rather a "subjective universe", a space weighted with meaning. Today, neuroscience provides a new way to look at the brain’s capability to create a representation of the world. At the same time behavioural specialists are demonstrating that animals have a richer mental universe than previously known. Philosophical reflection thus finds itself with more experimental and objective data as well. Nearly a century after the publication of von Uexküll’s founding work ("Umwelt und Innenwelt der Tiere" was published in 1909), neurobiologists, psychologists, sociologists, anthropologists, ethologists, and philosophers revisit his mail concept at the light of modern science
Download or read book Simplexity written by Alain Berthoz and published by Odile Jacob. This book was released on 2018-12-20 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Simplexity, as I understand it, is the range of solutions living organisms have found, despite the complexity of natural processes, to enable the brain to prepare an action and plan for the consequences of it. These solutions are simplifying principles that enable the processing of information or situations, by taking into account past experience and anticipating the future. They are neither caricatures, shortcuts, or summaries. They are new ways of asking questions, sometimes at the cost of occasional detours, in order to achieve faster, more elegant, more effective actions.” A. B. As Alain Berthoz demonstrates in this profoundly original book, simplicity is never easy; it requires suppressing, selecting, connecting, thinking, in order to then act in the best way possible. And what if we, in turn, are inspired by the living world to process the complexity that surrounds us? Alain Berthoz is professor at the Collège de France where he is co-director of the Laboratoire de physiologie de la perception et de l’action. [Laboratory for the physiology of perception and action]. He is a member of the French Academy of Sciences, and is the author of Le Sens du mouvement [The Brain's Sense of Movement] and La Décision [Emotion and Reason].

Download or read book Variation in Working Memory written by Andrew Conway and published by Oxford University Press. This book was released on 2008-02-13 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Working memory--the ability to keep important information in mind while comprehending, thinking, and acting--varies considerably from person to person and changes dramatically during each person's life. Understanding such individual and developmental differences is crucial because working memory is a major contributor to general intellectual functioning. This volume offers a state-of-the-art, integrative, and comprehensive approach to understanding variation in working memory by presenting explicit, detailed comparisons of the leading theories. It incorporates views from the different research groups that operate on each side of the Atlantic, and covers working-memory research on a wide variety of populations, including healthy adults, children with and without learning difficulties, older adults, and adults and children with neurological disorders. A particular strength of this volume is that each research group explicitly addresses the same set of theoretical questions, from the perspective of both their own theoretical and experimental work and from the perspective of relevant alternative approaches. Through these questions, each research group considers their overarching theory of working memory, specifies the critical sources of working memory variation according to their theory, reflects on the compatibility of their approach with other approaches, and assesses their contribution to general working memory theory. This shared focus across chapters unifies the volume and highlights the similarities and differences among the various theories. Each chapter includes both a summary of research positions and a detailed discussion of each position. Variation in Working Memory achieves coherence across its chapters, while presenting the entire range of current theoretical and experimental approaches to variation in working memory.

Book excerpt: NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.

Download or read book Elsevier s Dictionary of Medicine and Biology written by G. Konstantinidis and published by Elsevier. This book was released on 2005-08-18 with total page 2590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dictionaries are didactic books used as consultation instruments for self-teaching. They are composed by an ordered set of linguistic units which reflects a double structure, the macrostructure which correspond to the word list and the microstructure that refers to the contents of each lemma. The great value of dictionaries nests in the fact that they establish a standard nomenclature and prevent in that way the appearance of new useless synonyms.This dictionary contains a total of about 27.500 main English entries, and over of 130.000 translations that should normally sufficiently cover all fields of life sciences. The basic criteria used to accept a word a part of the dictionary during the development period in order of importance were usage, up-to-dateness, specificity, simplicity and conceptual relationships. The dictionary meets the standards of higher education and covers all main fields of life sciences by setting its primary focus on the vastly developing fields of cell biology, biochemistry, molecular biology, immunology, developmental biology, microbiology, genetics and also the fields of human anatomy, histology, pathology, physiology, zoology and botany.The fields of ecology, paleontology, systematics, evolution, biostatistics, plant physiology, plant anatomy, plant histology, biometry and lab techniques have been sufficiently covered but in a more general manner. The latest Latin international anatomical terminology "Terminologia Anatomica" or "TA" has been fully incorporated and all anatomical entries have been given their international Latin TA synonym. This dictionary will be a valuable and helpful tool for all scientists, teachers, students and generally all those that work within the fields of life sciences.

Download or read book Self objectification in Women written by Stacey Tantleff-Dunn and published by American Psychological Association (APA). This book was released on 2011 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Modern industrialized society chronically and pervasively objectifies the female body, and many women have come to view themselves through the lens of an external observer, habitually monitoring their own appearance whether in public or private settings. Given the negative effects associated with self-objectification--such as body shame, appearance anxiety, depression, and disordered eating--an empirically based approach to researching and counteracting self-objectification is critical. This book integrates recent research developments and current clinical knowledge on self-objectification in women. Using Barbara L. Fredrickson and Tomi-Ann Roberts' objectification theory as a framework, the contributors address various aspects of the theory, including evidence for and causes of self-objectification across the life span, psychological consequences, and associated mental health risks. The book also discusses various scales for measuring self-objectification, as well as approaches to prevent and disrupt this phenomenon. With research from a variety of disciplines--psychology, sociology, anthropology, women's studies, and political science--this book should be read by everyone interested in the well-being of women"--Publicity materials.
