People with Larger Amygdala Have Better Social Relationships
London, Dec 29. -People with a larger amygdala tend to be more sociable, according to results of a study published in the latest edition of the journal Nature Neuroscience.
Researchers from Massachusetts General Hospital and Harvard Medical School, in United States, based these results on a study of people from 19 to 83 years who completed a questionnaire about the quality of their social relationships.
Each person underwent a brain scan to measure the size of brain structures, including the amygdala.
Researchers concluded that while the better the relationships, the size of the amygdala is larger.
Previous studies in primates also showed that bond.
This finding confirms the "social brain" hypothesis, which indicates that the amygdala in humans evolved to better manage social relationships, according to Lisa Feldman, author of the study.
The researchers also analyzed the way the amygdala and other parts of the brain are related to the social behavior of humans.
Research team also studies how defects in those parts of the brain can affect social behavior in neurological and psychiatric diseases. (Prensa Latina)
