Basal ganglia is a collection of gray matter in the cerebrum including the corpus striatum, amygdala and claustrum. These nuclei are strongly interconnected with the cerebral cortex, thalamus, and brain-stem, as well as several other brain areas.
COMPONENTS of Basal Ganglia
- Dorsal striatum (caudate nucleus and putamen)
- Ventral striatum (nucleus accumbens and olfactory tubercle)
- Globus pallidus
- Ventral pallidum
- Substantia nigra
- Subthalamic nucleus.
Functions of Basal Ganglia
The basal ganglia are associated with a variety of functions including: control of voluntary motor movements, procedural learning, routine behaviors or “habits” such as eye movements, cognition and emotion.
The basal ganglia are studied extensively in the context of two disorders of the basal ganglia: Parkinson’s disease and Huntington’s disease.
