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 represe...
