Brain & Prosopagnosia, 2

It appears to involve—no surprise—the part of the brain involved in facial recognition. A group of cells known as the fusiform gyrus, is in each cerebral hemisphere at the junction of the parietal and occipital lobes near the back of the head. Interestingly, the right hemisphere fusiform gyrus is more often involved in familiar face recognition than the left. So, damage to the right fusiform could be more impactful than damage to the left. Prosopagnosia has been defined as a cognitive disorder of facial perception, marked by an impaired ability to recognize familiar faces including impaired self-recognition of one’s own face. It is important to note that other aspects of visual processing such as object discrimination and intellectual functions as in decision making remain intact. More tomorrow
