Are you a giver? Brain scan finds the truth
WASHINGTON (Reuters) - Altruism, one of the most difficult human behaviors to define, can be detected in brain scans, U.S. researchers reported on Sunday.
They found activity in a specific area of the brain could predict altruistic behavior -- and people's own reports of how selfish or giving they are.
"Although understanding the function of this brain region may not necessarily identify what drives people like Mother Theresa, it may give clues to the origins of important social behaviors like altruism," said Scott Huettel, a neuroscientist at Duke University in North Carolina who led the study.

They set up an experiment in which they put 45 college students into a functional magnetic resonance imaging scanner, which can take real-time images of brain activity.
They gave the students various games to play, and told them that winning earned cash for either themselves or for a charity. The students had chosen the charities beforehand from a list, the researchers report in the journal Nature Neuroscience.
The students reacted differently depending on whether they won for themselves or for charity with the ones who described themselves as altruistic responding more strongly.
"The game involved reacting as fast as one can to the appearance of a target; if one responds fast enough, then money was earned," Huettel said.
