Research Interests

  • Motor control, motor learning, physiology, cerebellum, motor cortex, psychophysics and behavior

Research Projects

  • We have a number of ongoing research projects in the laboratory:
    1. Pausing in cerebellar neurons: there is controversy over whether cerebellum neurons exhibit periods of long pauses in their activity and whether this has any functional relevance. We are exploring this question in by recording in awake behaving animals and correlating these pauses with the activity of the animals.
    2. Activity of the cerebellum during reaching movements. How does the cerebellum code for error in reaching movements and how does it correct mistakes that result from predictable perturbations of the movement?
    3. Do we learn by watching and how? What is the mechanism that allows observation of another person practicing to improve our own performance?
    4. Models of reaching movements. Can we build a model that explains the path that our hand takes during a reaching movement and the way that path changes over the course of training? Can we build a model that explains the role of the cerebellum in correcting our movements from trial to trial and from day to day?

Research Abstract

  • My laboratory will focus on physiological and behavioral aspects of motor control and motor learning. The main focus of my research will be the study of adaptation to perturbing forces during reaching movements. This simple task will serve as a vehicle for studying the physiology of the cerebellum, the relationship of long term and short term motor learning, the role of conscious awareness in motor control, and other topics.
