Abstract

Receptive fields were determined for recording sites in cortical areas 1, 2 and 5 in macaque monkeys. While a mixture of cutaneous and deep receptors were represented in most regions of area 2, a specific mediolateral level of area 2 was highly responsive to cutaneous input. Anteroposterior rows of recording sites across areas 1, 2 and 5 at this mediolateral location revealed a continuous sequence of cutaneous receptive fields proceeding from the occiput and face in area 1 to the forearm and hand in area 5.
