Abstract Background Planning and execution of reaching requires a series of computational processes that involve localization of both the target and initial arm position and the translation of this spatial information into appropriate motor commands that bring the hand to the target. We have investigated the effects of shifting the visual field on visuomotor control using a virtual visual environment in order to determine how changes in visuo-spatial relations alter motor planning during a reach. Methods Five healthy subjects were seated in front of an immersive .
