Hyperacute motion detection by the lateral eyes of jumping spiders.

abstract：:Previous research has shown that cognitive and motor visual systems have separate maps of visual space because spatial values in them can be manipulated independently. Here we ask whether the motor map in turn can be divided into separate representations of space. Forty large saccadic eye movements in darkness resulte...
