Brain circuits and personalities

The May/june issue of Scientific American Mind quotes a recent study in PLoS One. Here researchers looked for brain regions that tended to activate together (closely linked areas) and tried to correlate that with personality traits (neuroticism, extroversion, openness to exerience, agreeableness and conscientiousness).

Turns out that brain areas labelled with the same color are more tightly connected in people who score higher on the personality trait printed above (the illustration) in that color. White areas represent overlapping personality domains.

A nice (interesting) result!
