Brain region associated with selfishness

Brain region associated with selfishness.

People with damage to a specific part of the brain entrusted unexpectedly large amounts of money to complete strangers. In an investment game played in the lab, three women with damage to a small part of the brain called the basolateral amygdala handed over nearly twice as much money as healthy people.

The results suggest that normally, the basolateral amygdala enables selfishness — putting the squeeze on generosity.
