(PhysOrg.com) -- A new study by a Northeastern University researcher and her colleagues indicates that the size of a certain part of the human brain plays a significant role in determining the breadth of social relationships. Scientists found that the amygdala, a small structure in the temporal lobe of the brain, appears to be important to a rich and varied social life among adult humans. Their finding, published in the journal Nature Neuroscience, provides insight into how abnormalities in regions of the brain may affect social behavior in neurologic and psychiatric disorders.
