Une question fondamentale en neuroscience, ainsi que dans de nombreuses disciplines s’intéressant à la compréhension du comportement, telles que la psychologie, l’Economie, et la sociologie, concerne les processus décisionnels par lesquels les animaux et les humains sélectionnent des actions renforcées positivement ou négativement. Les processus décisionnels ainsi que leur base neuronale demeurent mal compris. D’autre part de nombreuses études ont révélé que les humains ainsi que les animaux prennent souvent des décisions sous-optimales. Notre principal objectif a été de comprendre la raison de ces comportements sous-optimaux. Par ailleurs, l’altération des processus sous-tendant la prise de décision, entraîne des pathologies. La compréhens...
