Saccadic command signals in the superior colliculus: implications for sensorimotor transformations.
Recent findings concerning the anatomical and functional organization of the deep division of the primate superior colliculus are summarized. These data are interpreted as supporting the hypothesis that the deeper layers of the superior colliculus are organized in motor, rather than sensory, coordinates. According to this hypothesis, a dynamic remapping of sensory signals is required for interfacing with the map of motor error space contained in the superior colliculus.
