The organization of behavioral repertoire in motor cortex
M. Graziano. Annual Review of Neuroscience, (2006)
Abstract
Motor cortex in the primate brain was once thought to contain a simple
map of the body's muscles. Recent evidence suggests, however, that
it operates at a radically more complex level, coordinating behaviorally
useful actions. Specific subregions of motor cortex may emphasize
different ethologically relevant categories of behavior, such as
interactions between the hand and the mouth, reaching motions, or
defensive maneuvers to protect the body surface from impending impact.
Single neurons in motor cortex may contribute to these behaviors
by means of their broad tuning to idiosyncratic, multijoint actions.
The mapping from cortex to muscles is not fixed, as was once thought,
but instead is fluid, changing continuously on the basis of feedback
in a manner that could support the control of higher-order movement
parameters. These findings suggest that the motor cortex participates
directly in organizing and controlling the animal's behavioral repertoire.
