Basal Ganglia

A group of subcortical nuclei (including the striatum, globus pallidus, substantia nigra, and subthalamic nucleus) involved in motor control, motor learning, executive functions, and emotional processing.

Key Functions:

• Initiation and control of voluntary movements.
• Motor learning and habit formation.
• Executive functions (planning, decision-making).
• Emotional and motivational processing.

Interacting Systems & Components:

• Striatum (caudate nucleus and putamen)
• Globus Pallidus
• Substantia Nigra
• Subthalamic Nucleus
• Thalamus (receives output from)
• Cerebral Cortex (interacts extensively with)
• Dopamine (critical neurotransmitter for function)
