Decision making and Neuroeconomics
The prefrontal cortex is divided into anatomically distinct sub-regions but their specific computational functions remain unclear. We combine fMRI and models of decision making developed in behavioral economics and mathematical psychology to investigate the computations performed by distinct prefrontal cortex regions. In particular, we investigate the functional contributions of orbitofrontal sub-regions and of the dorsolateral prefrontal cortex to the acquisition of values and the selection between options. We study processes involved during cognitive control, perceptual decision making and value-based decision making. A recent focus of interests is to characterize the computational principles and the neural mechanisms governing social decision making.
