The motion aftereffect as a universal phenomenon in sensory systems involved in spatial orientation. III. Aftereffect of motion adaptation in the somatosensory and vestibular systems

Abstract

The motion aftereffect may be considered as a consequence of visual illusions of self-motion (vection) and the persistence of sensory information processing. There is ample experimental evidence indicating a uniformity of mechanisms that underlie motion aftereffects in different modalities based on the principle of motion detectors. Currently, there is firm ground to believe that the motion aftereffect is intrinsic to all sensory systems involved in spatial orientation, that motion adaptation in one sensory system elicits changes in another one, and that such adaptation is of great adaptive importance for spatial orientation and motion of an organism. This review seeks to substantiate these ideas.
