FUSIFORM face area

Explanation:

Fusiform face area is the outer layer of the cerebrum located in the inferior temporal lobe of the brain. The major function of the fusiform face area is to recognise the faces.

When the fusiform face area is severely damaged it results in a neurological and visual impairment called Prosopagnosia. Prosopagnosia can also be referred to as face blindness.
