Abstract

Cue responses of neurons in the taste-related cortex of Japanese macaque monkeys were studied during a NaCl–water discrimination GO–NOGO task, to compare the correct and incorrect responses. Most neurons produced a steady pattern of discharges in response to a given cue at both correct and incorrect responses, presumably responding to the physicochemical nature of the cue. Some neurons showed the discharge pattern for a certain cue changing to that for another cue at task error, presumably representing the subsequent behavioral reaction or behavioral context. These neurons were mainly located in the precentral operculum and orbitofrontal cortex, and rarely in the primary gustatory area, area G.
