Imaging analysis studies on the brains of adults over 80 years of age with great memory demonstrates the neuroanatomical differences these elite sect of society display as they age. When compared with 50 - 60 year olds, these individuals, coined Super Agers, show unusual brain signatures characterized by three main components: a thicker, larger region of the cortex, significantly fewer neurofibrillary tangles and a large supply of a neuron called von Economo, which has been linked to higher social intelligence.
