Motor cortex
Videos
The motor cortex comprises interconnected fields on the posterior frontal lobe—chiefly Brodmann area 4 and area 6 —that plan, select and execute voluntary movements. These regions transform goals into
Topography of human motor cortex. Supplementary motor area labelled SMA.
Simplified microcircuit model of primary motor cortex highlighting prominent layer V output neurons (including Betz cells) and their projections.
Motor representations in non‑human primate frontal cortex identified with microstimulation and recording (schematic).
Corticospinal tract
Videos
The corticospinal tract is a white matter motor pathway starting at the cerebral cortex that terminates on lower motor neurons and interneurons in the spinal cord, controlling movements of the limbs a
