The claustrum (Latin for barrier) is a thin layer of grey matter lying between the extreme capsule and external capsule in the brain.

[edit] Anatomy
The thickness of this layer is 1-2 mm. The external capsule separates the claustrum from nucleus lentiformis. The extreme capsule on the other side separates it from the grey matter of the insula.
Very little is known about its function, although it has reciprocal connections with the cerebral cortex.
Some authors consider the claustrum to be a separate part from nuclei lentiformis, others a separate part of the insular cortex, while a third party of authors states that it consists of two areas or parts: insular and temporal.
Contemporary anatomy states that the claustrum and corpus amygdaloideum do not belong to the basal nuclei.[1] However, they are still classified among the basal ganglia in NeuroNames.
[edit] Function
Francis Crick, a neuroscientist who was keen on studying the neural correlate of consciousness, pointed to the claustrum as one of the most probable key components of consciousness in one of his last works.[2][3]
