Exercise 65

Albert Einstein's brain was of normal size, but a part of his parietal lobe was about 15% wider than normal. This area controls mathematical reasoning, imagery, and the ability to visualize objects in space. A particular groove in the area appeared much reduced, leading researchers to speculate that this might have allowed more synaptic connections to form than normal. What additional information would help to determine whether Einstein's brain distinctions could have accounted for his genius?
