Abstract

Single-unit activities were recorded in the area F2 of dorsal premotor cortex (PMd) and area F4 of ventral premotor cortex (PMv) while a monkey was performing a sequential motor task guided by recognition of figures (FRS). During the cue period, 52% (39/75) and 16.9% (13/77) of the task-related neurons exhibited changes in activities in the areas F2 and F4, respectively. During the touch period, 51% (38/75) and 87% (67/77) of the task-related neurons exhibited changes in activities in the areas F2 and F4, respectively. There were more cells responding to the cue signal in F2 than in F4. In contrast, there were more cells responding during the touch period in F4 than in F2. The present findings indicate that a lot of neurons in the PMd and PMv are differently involved in the FRS task.
