Control of Fine Finger Movements
Our lab investigates how the brain controls movements of the body. A longstanding line of investigation explores control of fine finger movements, like those used in typing, playing a musical instrument, or performing delicate surgery. We study how the motor cortex controls a rather complex set of muscles to achieve the required movement. On-going projects include the following:
- Principal components of hand kinematics and neurophysiological signals in motor cortex during reach to grasp movements. J Neurophysiol. In press. (2014 Jul 02).
- Rapid acquisition of novel interface control by small ensembles of arbitrarily selected primary motor cortex neurons. J Neurophysiol. In press. (2014 Jun 11).
- Primary Motor Cortex Neurons during Individuated Finger and Wrist Movements: Correlation of Spike Firing Rates with the Motion of Individual Digits versus Their Principal Components. Front Neurol. 5, 70. (2014 Jan 01).
