of the comprehensive The Neurology
of Eye
Movements (Oxford University Press, 1999), schizophrenics show consistent abnormalities in the
voluntary control of saccades, particularly in tasks requiring imagination, memory or prediction.
The function
of controlling voluntary movement and sensory processing is distributed across a wide set
of brain regions including the neocortex, the cerebellum, the brain stem and the spinal cord, which are all richly activated during any aspect
of voluntary movement and sensory perception.

control voluntary muscle
movement.
SMA is typically marked by the degeneration
of voluntary muscle
movement including the muscles that
control crawling, walking, swallowing or breathing.
Whereas there has been extensive work on the neural mechanisms that subserve
voluntary limb
movement, comparatively little is known about how the motor system modulates the mechanical properties
of the limb through the neural
control of limb stiffness.

of a traumatic brain injury that damages the myelin sheath
of the nerve cells; locked - in syndrome is caused by damage to the brain's vertical pons, a region that
controls voluntary movement.
