sciencehabit writes "Smart, successful, and well-connected: a good description of Albert Einstein and his brain. The father of relativity theory didn't live to see modern brain imaging techniques, but after his death his brain was sliced into sections and photographed. Now, scientists have used those cross-sectional photos to reveal a larger-than-average corpus callosum — the bundle of nerve fibers connecting the brain's two hemispheres. The thickness of Einstein's corpus callosum was greater than the average, and more nerve fibers connected key regions such as the two sides of the prefrontal cortex, which are responsible for complex thought and decision-making. Combined with previous evidence that parts of the physicist's brain were unusually large and intricately folded, the researchers suggest that this feature helps account for his extraordinary gifts."
