Cortical plasticity
Plasticité corticale
Les circuits néocorticaux sont des circuits hautement complexes, fonctionnellement sophistiqués et variés. Ils effectuent des calculs, donnant lieu à la cognition et au comportement. Nous cherchons à comprendre les mécanismes, façonnant les circuits néocorticaux lors de certains processus, tels que la formation de la mémoire ou dans les troubles du spectre autistique (TSA). Décrypter les mécanismes neurobiologiques sous-jacents nécessite une description de ces circuits et de leurs composants, en termes de fonction, de structure, de connectivité synaptique entre eux et d’autres structures cérébrales, et d’expression génique. Notre principale expertise consiste à étudier comment les caractéristiques intrinsèques de l’excitabilité des neurones donnent lieu à la puissance de calcul des circuits néocorticaux. Pour tester ces hypothèses, nous utilisons une combinaison de méthodes innovantes et collaborons avec des experts de renommée mondiale. Notre travail n’aboutira pas seulement à une meilleure compréhension de la formation de la mémoire et des mécanismes à la base des phénotypes autistiques, mais pourrait aussi conduire à de meilleures stratégies de ciblage de troubles cérébraux, comme les TSA et la maladie d’Alzheimer.
