Abstract
Vection is similar to self-motion perception, which may be induced by the stabilizing sensory systems: visual, vestibular, and somatosensory. Vection is a common visual illusion from which inferences concerning visual-vestibular interaction may be drawn. There are three kinds of vection: circular vection, roll vection, and linear vection. Circular vection may be caused by the mismatch of the vision-horizontal semicircular canals, roll vection by that of the vision-vertical semicircular canals-otoliths, and linear vection by that of the vision-otoliths. It has been argued that the vestibular nuclei serve as a switch for the perceptual interpretation of seen motion.
