PMID-15888522[0] Motor cortex neural correlates of output kinematics and kinetics during isometric-force and arm-reaching tasks.
- see [1]
- recorded 132 units from the caudal M1
- two tasks: isometric and movement of a heavy mass, both to 8 peripheral targets.
- target location was digitized using a 'sonic digitizer'. trajectories look really good - the monkey was well trained.
- idea: part of M1 functions near the output (of course)
- evidence supporting this: M1 rasters during movement of the heavy mass show a triphasic profile: one to accelerate the mass, one to decelerate it, and another to hold it steady on target. see [2,3,4,5,6,7,8,9,10]
