Part 11: Teamwork11
Understanding faces involves several stages of cognition. Occipital lobe and the visual cortex for perception of basic structural elements of the image of a person's face. Temporal lobe and the fusiform gyrus for recognizing the face (connecting the face to the person and recording). Damage to this area can cause prosopagnosia or "face blindness," where the subject can identify objects (remember if something is the same object), but not faces (can recognize that something is a human face, but not remember or recognize a person from it), while still able to recognize known people by other methods. Voices, body movement patterns in gesture and gait, proving that the subject still has memories of the person.
