Publisher Summary The basal ganglia are often considered as parts of the motor system.
This concept is derived from the movement disorders arising in Parkinsonism, choreaand
hemiballism, from the projections of the primary motor and somatosensory cortex to the
putamen and subthalamic nucleus, and from movement-related neuronal activity in several
basal ganglia nuclei. The motor role of the basal ganglia can be extended to include
preparatory activity preceding the execution of limb and eye movements, which reflects …

The basal ganglia are often considered as parts of the motor system. This concept is derived
from the movement disorders arising in parkinsonism, chorea and hemiballism, from the
projections of the primary motor and somatosensory cortex to the putamen and subthalamic
nucleus, and from movement-related neuronal activity in several basal ganglia nuclei. The
motor role of the basal ganglia can be extended to include preparatory activity preceding the
execution of limb and eye movements which reflects neuronal access to stored information …
