Kind heart is down to brain; HEALTH NEWS.


Do you give readily to charity? Are you a Good Samaritan? If the answer is yes, that's because the right amygdala in your brain - the area associated with emotions - is bigger than average.

Scientists at Washington DC's Georgetown University scanned the brains of 39 volunteers, 19 of whom donated kidneys to strangers without expecting any payment.

The MRI scans showed that the right amygdala was on average 80% larger in the donors than in the control group.

And when each group was shown photographs of faces with tearful, angry or neutral expressions, the donors were much better at identifying fear in the faces than the control group, and their amygdalae showed greater activity.
