Perception becomes distorted when the spatial properties of the visual stimulus are abruptly changed. Psychophysical studies have shown some variables are critical for induction of spatial aftereffects and others have not. There have been few attempts to record single-cell response in the infrahuman visual system under stimulus conditions which yield aftereffects in human vision. The present paper outlines the assumptions of a model attributing aftereffects to neural inhibition. By consideration of psychophysical data within the context of this model, guidelines are provided for determination of the neural correlates of aftereffects.
