Where does genius come from? Is it rooted in biology, or in something environmental like 10,000 hours of practice?
Einstein’s brain might shed some light on this. When Einstein died, his brain was photographed and sectioned into slides. A study, reported in Science Daily, looked at 14 newly discovered photos. The conclusion: “Although the overall size and asymmetrical shape of Einstein’s brain were normal, the prefrontal, somatosensory, primary motor, parietal, temporal and occipital cortices were extraordinary”.
The prefrontal cortex is often linked to personality, executive function, and complex cognition.
Looks like genius is rooted in brain biology, at least partly.
