A study, "The cerebral cortex of Albert Einstein: a description and preliminary analysis of unpublished photographs",[1] was published on November 16, 2012, in the journal Brain. Dean Falk, an evolutionary anthropologist at Florida State University, led the study - which analyzed 14 recently discovered photographs - and described the brain: "Although the overall size and asymmetrical shape of Einstein's brain were normal, the prefrontal, somatosensory, primary motor, parietal, temporal and occipital cortices were extraordinary."[24] There was a fourth ridge (apart from the three normal people have) in Einstein's mid-frontal lobe involved in making plans and working memory.
