The basal ganglia (BG) have been implicated in various aspects of motor regulation and in cognitive processes. BG dysfunction is involved in Parkinson's Disease, Obsessive-Compulsive Disorder, and several other well-known medical problems. Currently, much research is focused on characterizing the unique roles of the various BG nuclei and their specific interactions with different cortical regions.

The goal of the BG project is to explore the function and functional connectivity of the various BG nuclei during predictable and unpredictable movement sequencing tasks. In particular, BG-cortical functional connectivity is being studied, with an emphasis on delineating pathways that are differentially activated during more automated and more unpredictable tasks. This exploration of functional connectivity complements existing structural data.
