A psychophysical investigation of the effects of controlled eye movements on the movement detectors of the human visual system.

Abstract The elevation of threshold for a moving grating was determined after adapting to a grating whose retinal image was made to move, either by moving the eyes or by moving the grating itself. The elevation was directionally specific, and depended only on the type of retinal image movement and not on the way in which that movement was produced. It is concluded that the site of adaptation of human movement detectors precedes the site of incorporation of the corollary discharge from the eye movement control centres.
