Book Description
La mémoire de travail (MT) est un ensemble de processus cognitifs permettant la mise en représentation mentale d’informations et leur utilisation pour agir. Elle permet l’émergence de fonctions élaborées telles que le raisonnement ou la planification. La MT repose, entre autres, sur les propriétés du cortex préfrontal latéral (CPFL). Les théories actuelles proposent une division de cette structure en différentes régions fonctionnelles, spécifiques soit des informations à traiter (domaine visuel ou verbal) soit du traitement à effectuer (maintien en mémoire, manipulation, action). Ainsi notre objectif est de préciser dans quels processus de MT le CPFL est spécifiquement impliqué et quel est le principe d’organisation fonctionnelle de cette région. Les travaux de cette thèse s’appuient sur une approche multimodale combinant études lésionnelles modernes et IRM fonctionnelle. Les résultats montrent que le CPFL est impliqué dans la manipulation des informations et leur utilisation pour l’action, et que pour cela il est organisé en régions spécialisées pour un domaine d’information et d’autres qui ne le sont pas.Ces résultats posent la question de la connectivité entre ces régions et de son lien avec les fonctions cognitives élaborées.

Book Description
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 Description
This book collects the results of clinical experience and research, as well as the opionions of the specialists who have studied in depth several rare and complex syndromes associated with "Continuous Spikes and Waves During Slow Sleep", the Landau-Kleffner syndrome, and related conditions. It also presents a wide-ranging collection of cases presented by the participants in the meeting, and analysed in its various clinical, electrophysiological and psycho-intellectual aspects. The purpose of the book is to provide a thorough updated on specialised knowledge about the syndromes characterised by the presence of CSWS on the EEG, to bring out the many, still unanswered -- questions, and to stimulate further interdisciplinary research to verify the validity of present hypotheses, in order to clarify which preventive and therapeutic methods can best attain the control of such syndromes.

Did you know that you are more closely related to a mushroom than to a daisy? That dinosaurs are still among us? That the terms "fish" and "invertebrates" do not indicate scientific groupings? All this is the result of major changes in classification. This book diagrams the tree of life according to the most recent methods of this system.

Book Description
One of the most fascinating problems in Behavioural Neurology is the question of the cerebral organization for language during childhood. Acquired aphasia in children, albeit rare, is a unique circumstance in which to study the relations between language and the brain during cerebral maturation. Its study further contributes to our understanding of the recovery processes and brain plasticity during childhood. But while there is a great amount of information and experimental work on brain-behaviour relationships in adult subjects, the literature about the effects of focal brain lesions in children is both exiguous and scattered throughout scientific journals and books. We felt it was time to organize a meeting where scientists in this field could compare their experiences and discuss ideas coming from different areas of research. A workshop on Acquired Aphasia in Children was held in Sintra, Portugal, on September 13-15, 1990, and attended by 44 participants from 13 differents countries. The atmosphere was relaxed and informal and the group was kept small to achieve this effect. It was a very lively and pleasant meeting. Some consensus was indeed arrived at concerning methodological problems, definition of terms, and guidelines for future research. The main contributions are collected in this book which, we hope, will serve the scientific community as a reference work on Childhood Aphasia. I,P.M., AC.C.

Book Description
Neuroscience has paid only little attention to decision-making for many years. Although no field of science has cohered around this topic, a variety of researchers in different areas of neuroscience ranging from cellular physiology to neuropsychology and computational neuroscience have been engaged in working on this issue. Thus, the time seemed to be ripe to bring these researchers together and discuss the state of the art of the neurobiology of decision-making in a broad forum. This book is a collection of contributions presented at that forum in Paris in October 1994 organized by the Fondation IPSEN.
