Multiple representations of the body within the primary somatosensory cortex of primates

JH Kaas, RJ Nelson, M Sur, CS Lin, and MM Merzenich

Microelectrode mapping experiments indicate that the classical primary somatosensory cortex of monkeys consists of as many as four separate body representations rather than just one. Two complete body surface representations occupy cortical fields 3b and 1. In addition, area 2 contains an orderly representation of predominantly "deep" body tissues. Area 3a may constitute a fourth representation.
