Upon his death in 1955, Albert Einstein’s brain was removed,
fixed and photographed from multiple angles. It was then sectioned into 240
blocks, and histological slides were prepared. At the time, a roadmap was drawn
that illustrates the location within the brain of each block and its associated
slides. Here we describe the external gross neuroanatomy of Einstein’s entire
cerebral cortex from 14 recently discovered photographs, most of which were
taken from unconventional angles. Two of the photographs reveal sulcal patterns
of the medial surfaces of the hemispheres, and another shows the neuroanatomy
of the right (exposed) insula. Most of Einstein’s sulci are identified, and
sulcal patterns in various parts of the brain are compared with those of 85
human brains that have been described in the literature.
