Selection of visual targets activates prelunate cortical cells in trained rhesus monkey.
Cells in monkey prelunate association cortex display an enhanced visual activity after the onset of a stimulus in the receptive field, when the stimulus is simultaneously selected as a target for a saccadic eye movement. In the present study we observed a separate activation which is independent of the passive visual on-response and occurs in a given cell when the animal saccades to a steady stimulus in its receptive field. The activation begins when the stimulus is selected for foveation before the eye actually moves, but is not necessarily predictive for an eye movement.
