Moderate levels of exercise may increase the brain’s flexibility and improve learning, a new study suggests.
The
visual cortex, the part of the brain that processes visual information,
loses the ability to “rewire” itself with age, making it more difficult
for adults to recover from injuries and illness, said Claudia Lunghi, a
neuroscientist at the University of Pisa and one of the study’s
authors.
In
a study in the journal Current Biology, she and her colleagues asked 20
adults to watch a movie with one eye patched while relaxing in a chair.
Later, the participants exercised on a stationary bike for 10-minute
intervals while watching a movie.
When
one eye is patched, the visual cortex compensates for the limited input
by increasing its activity level. Dr. Lunghi and her colleagues tested
the imbalance in strength between the participants’ eyes after the movie
— a measure of changeability in the visual cortex.

Another reason, I guess, why we all need to exercise...
