Motor Areas
The primary motor cortex receives terminating thalamocortical fibers from the VL nucleus of the thalamus. This is the primary pathway involved in the transference of cerebellar input to the primary motor cortex. The VA projects widely across the inferior parietal and premotor cortex. Other Non-specific thalamocortical projections, those that originate in the dorsal-medial nuclei of the thalamus, terminate in the prefrontal cortex and have subsequent projections to associative premotor areas via collateral connections. The Cortico-basal ganglia-thalamocortical loop has been traditionally associated with reward-learning and though has also been noted by some researchers to have a modulatory effect on thalamocortical network functioning–this is due to inherent activation of the premotor areas connecting the VA nucleus with the cortex.

Famous quotes containing the words motor and/or areas:
“What shall we do with country quiet now?
A motor drones insanely in the blue
Like a bad bird in a dream.”
—Babette Deutsch (1895–1982)
“Helping children at a level of genuine intellectual inquiry takes imagination on the part of the adult. Even more, it takes the courage to become a resource in unfamiliar areas of knowledge and in ones for which one has no taste. But parents, no less than teachers, must respect a child’s mind and not exploit it for their own vanity or ambition, or to soothe their own anxiety.”
—Dorothy H. Cohen (20th century)
