Marjorie Taylor's piece of work titled Warm
Glow is based on her husband's and his colleagues'
fMRI scans of brains. The colored areas shown represent the brain regions that
showed heightened activity that are related to making charitable decisions.

In
Elizabeth Svoboda's article "What Makes a Hero?", the author makes an
attempt to prove that there is a scientific reasoning behind heroic feats to
the readers of Discovery magazines. Svoboda shows how characteristics like valor
and fearlessness tie with a person's brain. She starts out with an anecdote of
a woman named Shirley Dygert in order to hook her readers in and to put them in
the shoes of a 54-year-old woman who was saved by a guy named Dave Hartsock.
Dygert was skydiving for the first time with her instructor, but as they opened
the parachute to stop their free fall, the chute did not open all the way and
the backup parachute became tangled. Hartsock decided to position his body so
that he could cushion Dygert's fall, and when they landed, he suffered a severe
blow on his spinal cord, ultimately paralyzing him from the neck down. Dygert
exclaimed that his action "absolutely amazed" her because he had
"that much love for another person." "Why?" Svoboda asks,
allowing the audience to participate and think. Apparently, when a person does
a good deed, a place in the brain called nucleus accumbens releases the
pleasure chemical dopamine. While egoists show less activity in this part of
the brain when donating their money to charity, altruists show more. Svoboda draws
the comparison between the satisfaction of giving money to others and the satisfaction of ingesting an addicting
drug to show how good it feels to do a heroic deed. Recent discovery shows how
meditating can help people to train their minds to be more selfless, and the
researchers found this out by having some participants to practice meditation while
having others to practice a technique known as cognitive reappraisal. When both
groups played the game, the participants who practiced meditation helped out
unfortunate victims more than the other participants did. By adding all these
details about the experiment, Svoboda increases her credibility a lot. I
believe that her use of anecdotes, comparison, and descriptive details really
allowed me to see bravery in a whole new way.
