Mapping is not sufficient for specifying position in visual space.
The general view is that one knows where an object is located in visual space on the basis of which neurons it activates. But there is reason to believe that a radically different method of specifying position is needed, one which identifies the position using coordinates. Those who study motor systems assume such coordinates, but the question of how the sensory system could derive these values is given no attention.
