The Biology of Altruism: Good Deeds May Be Rooted in the Brain
Geege Schuman stashed this in Compassion
The amygdala was significantly larger in the altruists compared to those who had never donated an organ. Additionally, the amygdala in the altruists was extremely sensitive to the pictures of people displaying fear or distress.
These findings are the polar opposite to research Marsh conducted on a group of psychopaths. Using the same tests as with the altruists, Marsh found that psychopaths have significantly smaller, less active amygdalas. More evidence that the amygdala may be the brain's emotional compass, super-sensitive in altruists and blunted in psychopaths, who seem unresponsive to someone else's distress or fear.
So all we have to do is increase the size of the amygdala in people and then no more psychopaths?
Btw, this woman IS an extraordinary altruist:
Four years ago, Angela Stimpson agreed to donate a kidney to a complete stranger.
"The only thing I knew about my recipient was that she was a female and she lived in Bakersfield, Calif.," Stimpson says.
It was a true act of altruism — Stimpson risked pain and suffering to help another. So why did she do it? It involved major surgery, her donation was anonymous, and she wasn't paid.
"At that time in my life, I was 42 years old. I was single, I had no children," Stimpson says. "I loved my life, but I would often question what my purpose is."
When she read about the desperate need for kidneys, Stimpson, a graphic artist who lives in Albany, N.Y., says she found her purpose. She now blogs about her experience and encourages others to become donors.
People like Stimpson are "extraordinary altruists," according to Abigail Marsh. She's an associate professor of psychology at Georgetown University and one of the country's leading researchers into altruism.
Marsh herself was the beneficiary of extraordinary altruism when she was 20. She got into a freak highway accident and ended up stalled in the fast lane facing oncoming traffic. A man dodged traffic to come to her aid and help get her car started. He saved her life, she says, then disappeared before she could ask his name.
