Piers Anthony on the Brain

"I
matched the Discover video The Brain. The amygdala controls
emotion, such as fear. The military trains recruits to control their
fear reaction, because otherwise they can make lethal mistakes when
panicked. The frontal lobes are the most recently developed part of
the brain, and they interact with the amygdala; they can moderate the
panic. Suffocating under water is another problem; the amygdala
presses the panic button. Training shows them how to handle this.
Most SEAL candidates wash out because of panic. Practice in your mind
and it helps you get through. Replace bad thoughts with good
thoughts. Breathing control. Reproduction is another powerful drive,
and orgasm is potent ecstasy also triggered by the amygdala. The
brain stem generates dopamine, the pleasure hormone, but the male and
female brains react differently. The female orgasm shuts down most of
the woman's brain, sometimes rendering her unconscious, while the
male remains conscious, perhaps to be ready to defend them in case of
danger. Handling danger brings exhilaration, so taking risks is
tempting. Some people seek risk more than others. But what of those
who don't have these reactions, who lack a conscience, like
psychopaths or serial killers? (I think they mean sociopaths, but
never mind.) What makes some brains evil? Psychopaths are not
bothered as much by their mistakes. They have smaller amygdalas. Less
capacity for empathy. And memory: Thanks to that, the brain is
constantly traveling through time. What about photographic memory? A
person with that is an artistic savant, with incredible visual
memory, but lacking in other respects. Memory forms throughout the
brain, but the hippocampus is critical; without it, new memories
can't form. Memory is essential to just about everything we do. The
cerebellum helps with practice. It takes 10,000 hours to get really
proficient, and the muscles develop some memory within themselves.
There can be performance anxiety. The brain can help a person win, or
help him lose. You need to be in the zone, everything just right.
Could there be a sixth sense, tuning into the minds of others? Can
some people respond to images before the images appear? Is
ESP—ExtraSensory Perception—possible? They are connecting
people's heads to computers and checking. There are so many questions
to answer!"
