claustrum

Thin neural sheet

The claustrum is a thin, irregular sheet of gray matter in the brain, tucked between the outer cortex and deeper structures.

Its function remains debated, but theories suggest it may integrate sensory information or coordinate conscious experience.

The name comes from the Latin for "enclosed place"—the structure is hidden, claustrally, between other brain regions.
