It is amazing how different parts of our brain perform

different functions.  We know, for example, the right fusiform gyrus, a fold in the brain, coordinates the neural systems that control facial perception and memory, and abnormalities in it cause face blindness.  It has now been shown that the anterior temporal lobe is critically involved in the retrieval of people's names.  There is hope that some day medical science will come up with a way to help people like you and me to better remember people's names.
