Much has been learned about how neurons in the central nervous system are related to various features of movement, but relatively little has been learned about voluntary control per se. This stems from the fact that voluntary control generally is coupled to body movement, muscle contractions, and sensory feedback.

We currently are exploring dexterous control of an avatar hand through a brain-computer interface. To address the challenge of controlling the complexity of the hand, we emphasize a variety of approaches beyond fixed, linear decoding of neural activity.

We recently found that instructions about which movement to perform, normally delivered with different light emitting diodes (LEDs), can be delivered instead with intracortical microstimulation (ICMS) in the premotor cortex (PM).

The hand often is used for manipulating an object, but much more is known about how the nervous system controls the reach and grasp that typically precedes manipulation. We are exploring the neural and muscular activity underlying manipulation, and how that relates to the activity that controls the preceding reach and grasp.
