Directional changes in the vestibular ocular response as a result of adaptation to optical tilt.
Before and after exposure to clockwise optical tilt, subjects' compensatory eye movements were recorded, as the head was oscillated around a vertical axis by the experimenter. An analysis of the horizontal and vertical components of eye movements showed a change in eye movement path in the clockwise direction. This corresponded to similar changes in visual spatial orientation judgments indicative of perceptual adaptation. It was suggested that long-term visual feedback serves to restore the compensatory nature of the eye movements which was altered by the introduction of the prism transformation.
