Visual receptive fields of single neurons and clusters of neurons were determined for recording sites in the occipital, caudal temporal and caudal parietal lobes of the owl monkey. In 7 experiments the visuotopic organization of the caudal third of the middle temporal gyrus was explored and a complete representation of the contralateral half of the visual field was revealed. This representation of the visual field (MT) corresponds to a histologically distinct area adjacent and rostral to area 19. The MT area is oval with its major axis approximately 6 mm long rostrocaudally and 4–5 mm wide mediolaterally. The horizontal meridian divides MT into a lateral portion representing the upper visual quadrant and a medial portion representing the lower quadrant. The center of gaze is reprented in the caudal portion of MT bordering area 19. The representation of the periphery of the visual field lies in rostral MT immediately medial and caudal to the caudal tip of the superior temporal sulcus.
