Scholars on both sides of the science-humanities divide have been known to feel that their counterparts just don't think in the same way. But could it be that their brains are actually different? Yes, it could, say Japanese neuroscientists Hikaru Takeuchi and colleagues, who have just published a paper about Brain structures in the sciences and humanities They report that there are significant group differences in brain structure between undergraduate students studying sciences vs. humanities subjects. Specifically, the scientists had more grey matter in the medial prefrontal cortex (p=0.035), but their humanist counterparts had a higher white matter density around the right hippocampus (p=0.018). On average.
