"We need a new framework for psychiatry — one that bridges the gap between brain circuits and the algorithms they implement, connecting both to meaningful clinical intervention."

 

Connecting neural circuits to cognition

How can understanding circuit mechanisms underlying cognitive control and flexibility inform therapies for psychiatric disorders and artificial intelligence? 

Dr. Halassa's research combines parametric behavioral tasks with physiological, genetic and optical manipulations to understand core circuit mechanisms and computational principles of cognitive function. His lab focuses on thalamocortical interactions that implement attention, executive control and decision-making. 

His lab's biggest contribution to the scientific community is identifying a precise non-relay function for the thalamus. The overarching goal of the his research is to establish a computational theory for the cognitive thalamus. His guiding hypothesis is that the mediodorsal thalamus gates inputs within and across frontal cortical networks to enable flexible behavior. He hopes that this knowledge will provide practical applications in two separate domains: decision-making abnormalities in human psychiatric disorders and flexible reasoning in artificial intelligence.
