According to paleoanthropologist Dean Falk at Florida State University, Einstein's brain (on the surface at least) looks different from other brains. At least a dozen subtle variations in his brain's surface have been identied, variations that may have heightened his ability to see physics in a new way. Part of Einstein's brain, the visual-spatial reasoning region, is believed to have been about 15% larger than average/normal brains, and the supramarginal gyrus was not divided with the Sylvian fissure. The inference is that his anatomy might have given Einstein an advantage in three-dimensional thinking (e.g., theory or relativity). Check it out.
