Single-unit activity related to active localization of acoustic and visual stimuli in the frontal cortex of the rhesus monkey.
Single-unit recordings were made in monkey periarcuate regions during the performance of limb movement tasks. A large class of neurons is described that appear to be involved in active localization of both acoustic and visual stimuli. These neurons failed to respond to stimuli of either modalities except in tasks where the location of the stimulus served as the cue for direction of movement.
