basal ganglia

basal ganglia

group of deep brain nuclei that contribute to motor control and coordination

caudate nucleus

c-shaped structure that is immediately lateral to and follows the curvature of the lateral ventricle

globus pallidus

triangular nucleus that can be divided into external and internal part

putamen

oval-shaped nucleus immediately lateral to the globus pallidus

substantia nigra

the dopamine-producing centre of the brain, involved in motor coordination and reward behaviours

subthalamic nucleus

small nucleus located inferior to the thalamus but superior to the substantia nigra

lentiform nucleus

putamen and globus pallidus

striatum

caudate nucleus and putamen

corpus striatum

caudate nucleus and lentiform nucleus

nucleus accumbens

nucleus considered to be part of the basal ganglia, but not involved in motor control, located at the anterior junction between the caudate nucleus and putamen

amygdala

small spherical nucleus considered to be part of the basal ganglia but not involved in motor control, involved in memory and emotion

internal capsule

bundle of white matter tracts between the lentiform nucleus and the thalamus, containing projection fibres

corona radiata

axons that pass from the internal capsule to the cortex
