Organization of claustro-cortical projections to the primary somatosensory area of primates.
Different fluorescent dyes were injected in the face (S1fa) and hand (S1hn) representations of the primary somatosensory cortex, involving both areas 3b and 1. Claustral neurons labeled by either S1fa or S1hn were divided in two populations. One population was located in the dorsal part of the nucleus: neurons labeled from S1fa were placed laterally to those labeled from S1hn. The second population was located more ventrally, with a rostro-caudal distribution of S1fa vs S1hn neurons. These findings demonstrate the existence of ordered and possibly multiple somatosensory representations in the monkey claustrum.
