Neuronal processing is self-centred and interaction oriented. (A) A hypothetical visual field. (B) The corresponding topological mapping of the image on the retina and on the primary visual cortex (V1). (C) The transformation of the topological mapping in the right associative visual cortices (V1 to V4): notice the transformation to a spherical coordinate system (angle α_n and distance d_n), that helps to map objects in terms of the direction (azimuth and elevation) of a movement to reach them.
