Most neurons in the prestriate area MT of the macaque monkey exhibit direction selectivity to moving visual stimuli. Deficits in the initiation of pursuit eye movements and those in the discrimination of the direction of moving random dot stimuli have been produced by MT lesion. Also, facilitation of the direction discrimination has been produced by MT microstimulation. These experiments provide evidence of causal relation between activities of MT neurons and motion perception. However, recent studies have shown that MT neurons are also affected by visual cues that are not directly involved in the motion perception. It is suggested that integration of motion-related inputs and other inputs observed in MT neurons is important for the segmentation of visual images into different objects.
