Prosophenosia


prosophenosia is inability to recognize faces. This occurs in people who have extensive damage on the medial undersides of both occipital lobes and along the medioventral surfaces of the temporal lobes Loss of these face recognition areas, strangely enough, results in little other abnormality of brain function.
One wonders why so much of the cerebral cortex should be reserved for the simple task of face recognition.
Most of our daily tasks involve associations with other people, and one can see the importance of
this intellectual function.
The occipital portion of this facial recognition area is contiguous with the visual cortex, and the temporal portion is closely associated with the limbic system that has to do with emotions, brain activation, and control of one’s behavioral response to the environment.
