The claustrum is located within the inner surface of the neocortex of the pallium, deep to the insula and separated from it by the extreme capsule. The basal ganglia are one of the components in the neural chain that controls the voluntary motor activity. The claustrum (plural: claustra) is a vertical curved sheet of subcortical grey matter oriented sagittally between the white matter tracts of the external capsule and extreme capsule. Historically, the amygdaloid complex and the claustrum were considered parts of the basal ganglia. These nuclei therefore belong to the enabling factors for consciousness. Although situated adjacent to structures of the basal ganglia, such as the putamen, the . The traditional definition of the basal ganglia included the corpus striatum, claustrum, and amygdaloid complex.
