ABSTRACT
The perception of objects requires global processes in which many elementary occurrences are bundled. Neurophysiology, which has mainly been concentrated on the receptive fields of individual cells, has difficulty in unravelling complicated networks. Nevertheless, neurophysiological discoveries have been made of higher processes of vision taking place beyond the primary visual cortex. As already has been mentioned, in apes cells have been found in the temporal lobe which are particularly sensitive to faces. It is remarkable that some cells only react to a face presented in a certain perspective, while others react irrespective of the position of the face: they are thus sensitive to a face in an objective axial system.
