Neural mechanism of decision making

Decision making is ubiquitous, and the ability to acquire and utilize knowledge about our environment for producing a series of most appropriate actions is essential for survival. The main goal of our research is to understand the brain mechanisms of such adaptive behavior. Current projects investigate the prefrontal and striatal mechanisms underlying the dynamic process of updating the values of various objects and actions through experience. Some of our experiments focus on the strategic planning of sequential actions during competitive interactions with computerized opponents. We are also interested the brain mechanisms underlying the estimation of temporal intervals and numerical quantities and behavioral control based on such estimates. 

Our research capitalizes on the insights from formal theories of economics and reinforcement learning as well as computational neuroscience of neural coding. We also develop novel behavioral paradigms that can probe the core processes of decision making. Combined with the use of multi-electrode recording systems, our research seeks to unravel the biological basis of cognition and willful actions.
