Dynamics of cortico-basal ganglia networks during movement and learning

Our group studies how neural dynamics in cortico-basal ganglia circuits are generated, and their role in reward-guided behavior and learning. As part of this effort we develop, and use, silicon microprobe electrode arrays to study the computational properties of large populations of neurons. We combine these large-scale recordings with complementary approaches, such as optogenetic stimulation, to determine the contribution of genetically and anatomically defined circuits on neural computation, and to establish causal links between neural activity and animal behavior.
