Representations of the face, teeth and oral cavity in areas 3b and 1 of somatosensory cortex in squirrel monkeys.
The somatotopic organization of low threshold inputs from the face and head was determined in the lateral portion of areas 3b and 1 in squirrel monkeys. A complete, topographically organized representation was found in area 3b, and a separate, roughly parallel representation was found in adjacent area 1. In addition, there was evidence for remarkable individual variability in the representation of the lips in area 3b.
