This book was released on 1986 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les comportements sont modifiés par l'apprentissage et la mémoire. L'apprentissage constitue l'acquisition des informations, et la mémoire assure leur rétention. Ces deux phénomènes constituent des processus dynamiques de l'utilisation de l'information par le cerveau. Cette utilisation permet a tout organisme vivant de générer des modifications comportementales en réponse à certaines conditions environnementales. Les modifications peuvent être transitoires ou permanentes. Ces modifications dépendent de mécanismes neuronaux multiples et variés : biophysiques, biochimiques, morphologiques psychologiques, etc. Ces mécanismes peuvent être fondamentaux ou modulateurs. La complexité de l'organisation du système nerveux chez les vertébrés, y compris l'homme et les invertébrés rend difficile l'étude de l'apprentissage et de la mémoire. Cependant, les travaux théoriques et expérimentaux ont permis la suggestion de plusieurs hypothèses et l'élaboration de divers modèles qui rendent compte de différents mécanismes cellulaires, de différents systèmes et circuits nerveux impliqués dans l'apprentissage et la mémoire. De très nombreux arguments expérimentaux et théoriques militent actuellement en faveur de systèmes multiples. L'analyse de ces travaux nous a permis de concevoir que les processus d'apprentissage et de mémoire se définiraient par des activités mnésiques transitoires et persistantes. Ces activités opèrent en interaction avec une autre activité importante, l'oubli. D'autre part ces processus s'organiseraient de la façon suivante: des processus d'apprentissage et de mémoire encéphalisés (vertébrés, y compris l'homme) ou centraux (invertébrés) et des processus de la base du cerveau, (notamment l'organisation mnésique de la locomotion, des réflexes, et des réponses motrices.). Ces deux systèmes auraient les structures corticales pour centre d'intégration supérieure. Plusieurs mécanismes cellulaires sont à l'oeuvre dans ces systèmes mnésiques, des mécanismes fondamentaux et des mécanismes neuromodulateurs.

Available in PDF, EPUB and Kindle. Book excerpt: Les substances lipidiques ont longtemps été négligées par les physiologistes, mais des recherches épidémiologiques les ont récemment portées sur le devant de la scène, notamment au travers de leur intérêt dans les domaines de la nutrition et surtout de la santé chez l’Homme. Outre leur importance énergétique, les lipides interviennent dans de nombreux mécanismes cellulaires dont les dérèglements peuvent conduire à des pathologies parfois graves. En effet, en plus de leur impact sur les maladies métaboliques, les systèmes cardiovasculaire et immunitaire et les processus de cancérisation, le système nerveux central peut lui aussi être altéré à des degrés divers par une carence ou un déséquilibre entre les constituants lipidiques ingérés. Après quelques rappels historiques sur la découverte des lipides et leur utilisation, une première partie décrit les principaux lipides présents dans notre ration alimentaire. Puis, les besoins avérés ou éventuels de l’Homme en divers acides gras, stérols et vitamines appartenant au groupe des lipides, sont passés en revue. Enfin, l’impact des principaux lipides sur des pathologies naguère encore peu explorées sous cet aspect est exposé en détail. Les lipides – Nutrition et santé présente, de façon synthétique, un très large panorama de toutes les facettes des lipides, des acides gras aux corps gras les moins abondants, mais tout aussi importants pour l’équilibre de notre organisme. Il permet aux spécialistes de revisiter les principales sources de lipides présentes dans notre alimentation en insistant sur leur production et leur composition. Cet ouvrage s’adresse aux chercheurs, médecins généralistes et spécialistes, diététiciens et étudiants évoluant dans de nombreux domaines tels que la biologie cellulaire, la nutrition ou encore la pharmacologie.

Download or read book Plant Behaviour and Intelligence written by A. J. Trewavas and published by . This book was released on 2014 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a convincing argument for the view that whole cells and whole plants growing in competitive wild conditions show aspects of plant behaviour that can be accurately described as 'intelligent'. Trewavas argues that behaviour, like intelligence, must be assessed within the constraints of the anatomical and physiological framework of the organism in question. The fact that plants do not have centralized nervous systems for example, does not exclude intelligent behaviour. Outside the human dimension, culture is thought largely absent and fitness is the biological property of value. Thus, solving environmental problems that threaten to reduce fitness is another way of viewing intelligent behaviour and has a similar meaning to adaptively variable behaviour. The capacity to solve these problems might be considered to vary in different organisms, but variation does not mean absence. By extending these ideas into a book that allows a critical and amplified discussion, the author hopes to raise an awareness of the concept of purposive behaviour in plants.
Download or read book Neuroscientific Foundations of Anesthesiology written by George A. Mashour and published by Oxford University Press. This book was released on 2011-10-05 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the perioperative care of patients by anesthesiologists draws on diverse clinical skills, the principles of anesthesiology and pain management are rooted in the neurosciences. The Neuroscientific Foundations of Anesthesiology thoroughly examines the anesthetic modulation of the central, peripheral, and autonomic nervous systems and will help redefine anesthesiology as a fundamentally neuroscientific field. The book is organized by sections, with each focusing on a different part of the nervous system. State-of-the-art chapters written by thought-leaders in anesthesiology and neuroscience provide a novel and invaluable resource.
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

Book excerpt: An up-to-date overview of the current status of research on the full scope of synaptic plasticity, including synaptic remodeling in response to damage, long-term depression and long-term potentiation, and learning and memory.Synaptic Plasticity presents an up-to-date overview of the current status of research on the full scope of synaptic plasticity, including synaptic remodeling in response to damage, long-term depression and long-term potentiation, and learning and memory. The contributions are written by leading experts in the field and cover approaches from biochemical, anatomical, physiological, behavioral, and computational levels. They offer hypotheses concerning the molecular and cellular mechanisms that are responsible for the various manifestations of synaptic plasticity and propose models explaining how these cellular events can be linked to the functional and behavioral expressions of these adaptive principles.

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 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 The Adventures Of Roderick Random written by Tobias Smollett and published by Double 9 Books. This book was released on 2023-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Adventures of Roderick Random is a picaresque novel written by Tobias Smollett written before 1748. The book follows the misadventures of the eponymous main character, Roderick Random, as he navigates through life in 18th-century Britain. Roderick is a young man of humble origins who dreams of making his fortune and rising in society. However, he is constantly beset by misfortune and finds himself at the mercy of cruel fate and the nefarious actions of those around him. Throughout the novel, Roderick experiences a series of wild and often comical adventures, including being press-ganged into the Navy, working as a quack doctor, and falling in love with a woman who turns out to be a thief. The Adventures of Roderick Random is considered one of the earliest and most influential examples of the picaresque novel genre, which portrays the adventures of a rogue or antiheroic protagonist. It remains a beloved classic of English literature and a testament to Smollett's skill as a writer.
