The claustrum, which is suspected to be present in all mammals, is a fairly thin (fraction of 1 mm to multiple mms) vertical curved sheet of subcortical gray matter oriented sagittally between the white matter tracts of the external capsule and extreme capsule. The Claustrum is lateral to the putamen and medial to the insular cortex and is considered by some sources to be part of the basal ganglia. There are lateral and medial tracts connecting t...

The claustrum, which is suspected to be present in all mammals, is a fairly thin (fraction of 1 mm to multiple mms) vertical curved sheet of subcortical gray matter oriented sagittally between the white matter tracts of the external capsule and extreme capsule. The Claustrum is lateral to the putamen and medial to the insular cortex and is considered by some sources to be part of the basal ganglia. There are lateral and medial tracts connecting to many cortices and perhaps to the hippocampus, the amygdala, and the caudate nucleus (connections with subcortical centers are a matter of debate).
One of the interesting features of the claustrum is the uniformity in the types and numbers of cells. Since there is no function segregation or structural inhomogeneity , when waves of information come through the claustrum, the neurons will be especially sensitive to the timing of the inputs. Experiments to discover the physiological role of the claustrum are performed much the same with other...
