Scientists Suggest Links Between Personality, Size of Brain Regions

The news item may be found here

Some highlights

  • Four out of the five principle personality “factors” as typically characterized by psychologists — conscientiousness, extraversion, neuroticism, agreeableness and openness/intellect — were associated with differences in regional brain mass
  • Participants who described themselves as extroverted had a significantly larger medial orbitofrontol cortex — a part of the brain active in considering rewards. Perhaps not surprisingly, those self-described as conscientious had a bigger lateral prefrontal cortex
  • Personality is not an immutable force, given that the brain grows and changes in reaction to experience
  • Openness and intellect didn’t correspond to any particular brain structure
