Ah, the fusiform face area (FFA). It's the part(s) of your brain that recognizes faces, and, depending on your experience, other features (the example given in my class was a birdwatcher used his FFA to recognize bird species).
I have a habit of drawing the different parts of the brain as cute girls, and this is probably one of my favorite designs. She's based off of the Japanese noppera-bo (a yokai and/or ghost with no face) and some masks from noh theatre.
