Aftereffect of induced rotation: separation of inducing and static areas, and monocular component.

The present investigation shows that the aftereffect of induced rotation is observable when there is a large separation of inducing and static areas; it also has a substantial monocular component. These points are consistent with the possible involvement of lateral inhibition in movement detectors. (a) A recent study shows the importance of a peripheral inducing stimulus, and therefore presumably peripheral movement detectors; other psychophysical evidence shows that such detectors have large receptive fields and inhibitory surrounds. (b) Other effects probably involving lateral inhibition in movement detectors have a large monocular component.
