Head of Distributed Neural Dynamics and Control LabComputational models for cognitive functions have largely focused on the cortex and have thus overlooked important contributions from subcortical structures such as the thalamus, basal ganglia, and hippocampus. The Distributed Neural Dynamics and Control lab investigates how these subcortical structures interact with cortical circuits to subserve cognitive processes including memory, the ability to store and manipulate information in the absence of sensory input and in decision making, the process of selecting a course of action among multiple alternatives. We use tools from dynamical systems and control theory to simulate and analyze how distributed neural dynamics arise from multiregional neural circuits and how these dynamics are controlled for purposeful behavior. Moreover, we study the network and behavioral effects of exogenous neuromodulation of subcortical structures (e.g., as used in DBS) to discover new avenues for the treatment of neurological and psychiatric disorders.
