ABOUT
HUMAN BRAIN
REASON:
Just
reading this article involves engaging your frontal and occipital lobes to see
and comprehend. And of course your pituitary gland and hypothalamus are regulating
hormones, temperature, and much more.
.
REASON:
That's
because crossword puzzles only flex one part of your brain, which is word
finding (also called fluency.) So they might help you get better at word
finding, but not keep your brain sharp in general sense.
REASON:
People
once believed that we were born with a finite number of brain cells, and that
was it for life; if you damaged any of them you could never get them back.
Similarly, many scientists believed that the brain was unalterable; once it was
"broken," it could not be fixed.
Human body
can also generate new brain cells under the right circumstances.
REASON:
We
always hear that drinking booze can kill brain cells, but the truth is,
Alcoholics
can experience brain damage due to drinking, but it's not because alcohol kills
brain cells--it's because the alcohol can damage the dendrites that are found
at the end of the neurons, which causes problems in cell communication in the
brain.
