'Altruistic' brain region found

The brain area was more active among the altruistic group

Scientists say they have found the part of the brain that predicts whether a person will be selfish or an altruist.

Altruism - the tendency to help others without obvious benefit to oneself - appears to be linked to an area called the posterior superior temporal sulcus.

Using brain scans, the US investigators found this region related to a person's real-life unselfish behaviour.

The Duke University Medical Center study on 45 volunteers is published in Nature Neuroscience.
