Sociable people have 'bigger' brains

Sociable people have bigger brains, according to research produced by the University of Oxford.
People who possess lots of friends have six parts of the brain which are larger and better connected than those who are less sociable or who have smaller friendship groups, the study found.
Presenting her research on Tuesday, lead researcher MaryAnn Noonan told the Society for Neuroscience annual conference: “Human beings are naturally social creatures.
"Yet we know surprisingly little about how the brain manages our behaviour within our increasingly complex social lives -- or which parts of the brain falter when such behaviour breaks down in conditions such as autism and schizophrenia.”
