After analyzing this data and correcting for total brain volume (just like men’s bodies are, on average, larger than women’s bodies, so too are their brains), they discovered a number of apparent differences.
Among them was a relative size advantage for men in parts of the occipital lobe (which is associated with vision) and in the amygdala and hippocampus (regions that play important roles in emotion and memory). Women, on the other hand, had more gray matter in parts of the prefrontal cortex (which is associated with decisionmaking and self-control) and the insula (which has been connected with numerous functions, including emotion and the sense of taste). These results might seem to suggest that women have an edge over men in decisionmaking and that men have better memories, but it’s impossible to extrapolate such broad conclusions from Raznahan’s results.
