Abstract

A visuo-motor adaptation task was used to investigate the effects of this adaptation on the auditory-motor representation during reaching movements. We show that, following exposure to a rotated screen cursor-hand relationship, the movement paths during auditory conditions exhibited a similar pattern of aftereffects as those observed during movements to visual targets, indicating that the newly formed model of visuo-motor transformations for hand movement was available to the auditory-motor network for planning the hand movements. This plasticity in human sound localization does not require active cross-modal experience, and retention tests indicated that the newly formed internal model does not reside primarily within the central auditory system as suggested in past studies examining the plasticity of sound localization to distorted spatial vision.
