Evolution et Plasticite des Capacites Cognitives

Theme de Recheche

En interagissant avec son environnement, un individu est contraint à faire des choix quant aux informations qu’il va assimiler et quant au comportement à adopter selon les situations. Ainsi un individu doit balancer différentes sources d’information (informations sociales obtenues par interaction avec d’autres individus, information personnelles cumulées par l’individu lors de processus d’essais et d’erreurs…). Quels sont les facteurs qui influent sur cette balance ? Comment la sélection naturelle agit’ elle sur ces processus ? En intégrant à la fois des approches de biologie comportementales, de génétiques et de neurobiologie nous cherchons à comprendre comment interagissent ces différentes sources d’information et comment les individus adaptent leurs comportements à des conditions variées.

En prenant la drosophile comme modèle biologique, nous développons actuellement plusieurs thématiques:

Variations genetiques et developpementales des capacités cognitives

Trade off evolutif entre phases de mémoire

Effet de l’age parental sur le developpement des capacites cognitives

Interactions sociales et prises de décision chez Drosophila melanogaster

Influence de l’environnement social sur l’apprentissage olfactif.

Interactions sociales et apprentissage spatial :

Apprentissage social

Etude de la transmission sociale pour le choix du partenaire sexuel

Etude de la transmission sociale pour le choix du milieu de ponte.

Apprentissage multi sensoriel

Mots clés :

Apprentissage, Memoire, PLasticite Comportementale, Drosophila .
