Research Interest Summary

Cerebral basis for volitional movement and cortical neural prosthetics.

Our research is centered on two aspects of motor control cerebral mechanisms of volitional arm movement and cortical control of neural prosthetics. We use electrode arrays to record action potentials from populations of individual neurons in motor cortical areas while monkeys perform tasks related to reaching and drawing. A number of signal-processing and statistical analyses are performed on these data to extract movement-related information from the recorded activity. Students interested in our research program should have programming experience and ability/desire to train monkeys.
