What is the claim that faces are special? What evidence (fMRI, single unit recording, effects of brain damage) supports this claim?

Yes faces are special. We know that we can identify one by looking to his face. For that he has some kind of pattern in his face like the arrangement of eyes ,nose, eyebrows etc. We have special centres in our brainwhich recogy everyones face and their data is feeded there. So by looking to one's face we can identify them so fast. Even though years changes by looking at someone's face we can ideny that person from his facial pattern and that makes face much special. The evidence I use to draw out is the brain damage. Any damage to the later told area of the brain will lead to face blindness so that we will fail to identify that person. Face recognition is done in a holistic way. Seperate kind of stimuli is formed for different races and this will travel to brain and gives the identification of that face. So any kind of prosopagnosia present we can't identify that face. As the face has such a difference the face become so special and this lead to the use to same face for the biometric identification now a days.
