We study neural circuits in the rodent cerebellum involved with motor timing, coordination, and learning.  Our approaches include high-speed multiphoton imaging from cerebellar neurons in vivo during behavior, extracellular and intracellular electrophysiology in vivo as well as in acute brain slices, and anatomical techniques such as cell type-specific viral labeling to identify functional circuit pathways that connect the cerebellum with other brain regions.
