What aspects of movement are represented in the primary motor cortex (M1): relatively low-
level parameters like muscle force, or more abstract parameters like handpath? To examine�…

The basal ganglia and cerebellum are major subcortical structures that influence not only
movement, but putatively also cognition and affect. Both structures receive input from and�…

The traditional view that the basal ganglia are simply involved in the control of movement
has been challenged in recent years. Three lines of evidence indicate that the basal ganglia�…

The dominant view of cerebellar function has been that it is exclusively concerned with
motor control and coordination. Recent findings from neuroanatomical, behavioral, and�…

There has been a substantial change in our concepts about the cortical motor areas. It is
now clear that the frontal lobe of primates contains at least six premotor areas that project�…

We have used retrograde transport of wheat germ agglutinin conjugated to horseradish
peroxidase to examine the origin of thalamic input to the two premotor areas with the�…

The neural circuits that link the basal ganglia with the cerebral cortex are critically involved
in the generation and control of voluntary movement. Retrograde transneuronal transport of�…

We examined the topographic organization of corticospinal neurons in the primary motor
cortex and in the two premotor areas on the lateral surface of the hemisphere [ie, the dorsal�…

We have used retrograde transneuronal transport of neurotropic viruses to examine the
organization of the projections from the dentate nucleus of the cerebellum to “motor” and�…

One of the classical concepts concerning the cortical control of movement is that~
premotor'areas exist in the frontal lobe which have direct access to the primary motor cortex�…
