MIT Colloquium on the Brain and Cognition: Toward a single-trial view of motor preparation
|
| Description: |
Speaker: Krishna Shenoy, Stanford University
Location: Room 3002, Bldg 46, The Singleton Auditorium, MIT
Abstract:
Our seemingly effortless ability to reach out and swat a fly or grab a cup belies the sophisticated neural computations at work in our nervous system. It has long been recognized that, before moving, we somehow prepare neural activity such that, when called upon, the desired movement unfolds. But the goals of movement preparation and the underlying neural mechanisms remain poorly understood. I will describe some of our recent electrophysiological investigations of how premotor cortex prepares and helps execute movements. Our results suggest that the brain is attempting to optimize preparatory neural activity and can delay movement until this activity is sufficiently accurate. We note that the spiking activity during motor preparation exhibits dynamics beyond that driven by external stimulation, presumably reflecting the extensive recurrence of neural circuitry. We have been developing analysis methods for capturing the dynamics from (96 channel) simultaneous PMd neural recordings while monkeys perform delayed reaching tasks, and I will present recent work that examines the trial-by-trial neural trajectories during movement preparation and generation and their relationship with behavior. Characterizing these dynamics may reveal important features of neural computation, and may be useful for further increasing the performance of neural prostheses.
