Distinct temporal developments of visual motion and position representations for multi-stream visuomotor coordination.

ABSTRACT: A fundamental but controversial question in information coding of moving visual target is which of 'motion' or 'position' signal is employed in the brain for producing quick motor reactions. Prevailing theory assumed that visually guided reaching is driven always via target position representation influenced by various motion signals (e.g., target texture and surroundings). To rigorously examine this theory, we manipulated the nature of the influence of internal texture motion on the position representation of the target in reaching correction tasks. By focusing on the difference in illusory position shift of targets with the soft- and hard-edges, we succeeded in extracting the temporal development of an indirect effect only ascribed to changes in position representation. Our data revealed
