Pursuit neurons encode 3D space: is the cortex nervous and tensor?
Fukushima and colleagues have found single neurons in monkey frontal cortex that control pursuit eye movements by representing extra-personal space in a 3D-coordinate frame. These cells might link the 2D depiction of visual space by the retina with the need of the body to act in the 3D world. We could be on the verge of a new understanding of coordinate transformations serving sensory-motor integration in cerebral cortex.
