Basal nuclei

Definition

Basal nuclei are clusters of neurons located deep within the cerebral hemispheres. They play a crucial role in regulating voluntary motor movements, procedural learning, and routine behaviors or habits.

5 Must Know Facts For Your Next Test

1. Basal nuclei consist of structures such as the caudate nucleus, putamen, and globus pallidus.
2. They are involved in the control of movement by influencing motor pathways.
3. Damage to the basal nuclei can result in disorders like Parkinson's disease and Huntington's disease.
4. The basal nuclei receive input from the cerebral cortex and send output to the thalamus.
5. They help modulate the initiation and termination of movements.
