Definition

1. Noun:
   • A thin layer of grey matter in the brain: The claustrum is a thin, irregular sheet of neurons located deep within the cerebral hemispheres, situated between the insular cortex and the putamen (part of the lenticular nucleus). It is involved in integrating sensory information and coordinating cortical activity.

Usage Examples

• Noun:
  • Recent studies suggest the claustrum plays a role in consciousness and sensory integration.
  • The neuroscientist pointed to the claustrum on the brain scan.
