Neural Control of Hand and Finger Movements
Our lab investigates how the brain controls movements of the body, and translates our findings to advance brain-machine interface technology for restoration and repair of lost or damaged neurological function. A longstanding line of investigation explores control of fine finger movements, like those used in typing, playing a musical instrument, or performing delicate surgery. More recent work explores the combination of reaching, grasping, and manipulating. In both realms, we study how the brain controls a rather complex set of muscles to achieve the required movement.
On-going projects include the following:
- Controlling a Dexterous Hand From Neural Signals
- Multidimensional intracortical microstimulation to inject information into the brain.
- Reach, Grasp, and Manipulation
- Variation in the throughput from single cortico-motoneuronal cells to electromyographic activity
- Dimensionality reduction in the cortico-muscular system controlling the hand
- Principal components of hand kinematics and neurophysiological signals in motor cortex during reach to grasp movements. J Neurophysiol. 112, 1857-1870. (2014 Oct 15).
- Rapid acquisition of novel interface control by small ensembles of arbitrarily selected primary motor cortex neurons. J Neurophysiol. 112, 1528-48. (2014 Sep 15).
