  • Saccade Encoding

    The cerebellum encodes the kinematics of rapid eye movements (saccades) via a population response. The real-time speed and direction of the eye is encoded as a gain field.

  • Memory of Errors

    The brain controls how much it is willing to learn from the current error through a pricipled mechanism that depends on the history of past errors. Suggesting that the brain stores a memory of previous errors.

  • Effects of tDCS

    Anodal tDCS of the cerebellum increased the ability to form an internal model while cathodal stimulation reduced this error-dependent learning.

  • Paper accepted at Elife. Work with Stephen G. Lisberger and colleagues shows how careful analysis of behavior can reveal the properties of the learning circuit.

  • David received a K99/R00 award. David received a K99 through the National Eye Institute. The award will support two years of mentorship under Dr. Stephen G. Lisberger and 3 subsequent years of independent research.

  • Our work showing how errors are corrected by the oculomotor vermis of the cerebellum has been accepted at Nature Neuroscience.
