The cutaneous sensitivity of units in laminae VII and VIII of the cat.
The cutaneous sensitivity of units in laminae VII and VIII was compared to that of dorsal horn units in the same cats. There appeared to be a reversal of somatotopic organization between the dorsal and ventral horns. When this reversal was taken into account, it was apparent that most ventral horn units have localized receptive fields. They responded almost exclusively to intense, presumably noxious, stimulation of these discrete skin regions.
