講演タイトル：
　　The cortex-basal ganglia loop as a dynamic system:Theoretical and experimental approach
講演概要：
All animals have evolved rapid and efficient decision-making processes to solve complex and conflicting, sometimes life-threatening, choice situations. Nevertheless, these processes have reached an unprecedented degree of complexity in primates and, amongst them, humans. This has perhaps been at the price of an increased vulnerability to decision-making dysfunctions, as observed in several mental disorders. Because of this link between evolution and complexity of decision-making processes, it has commonly been assumed to be associated with the frontal cortical areas, often considered as the decision making centre of the brain. Here, I propose to re-evaluate this concept with an alternative view in which decision-making processes emerge from a distributed process spread through cortical-subcortical loops. I will focus the demonstration on the cortex-basal-ganglia loop and will present behavioural, electrophysiological and fMRI studies in human and non-human primates using multiple choice paradigms to support this theory.
