Anatomy and Physiology - Basal Ganglia

dorsal striatum

involved in sensorimotor activities; split into dorsomedial and dorsolateral striatum

ventral striatum

plays a role in reward and other limbic functions

globus pallidus

regulates voluntary movement; relay and control center

ventral pallidum

processes reward, motivation, reinforcement learning

caudate

plans movements, learning, memory, reward, motivation, processes emotions

putamen

regulates movements and influences learning

substantia nigra

produces dopamine, controls motor movements, coordinates muscle tone, learning, planning, reward

pars compacta

motor control, reward-based learning, temporal processing, sleep-wake cycle

pars reticulata

controls movement and eye movement

subthalamic nucleus

Facilitates voluntary movement and inhibits unwanted movements

lentiform nucleus

made of globus pallidus and putamen
