you can take a group of people that
never played the piano before and divide
them into two different groups and do
functional brain scans on both groups
one group they'll come for 2 hours a day
for 5 days and they'll practice these
one-handed scales and chords now you
learn something new you make new
Connections in your brain you get some
instruction you get your body involved
when you get your body involved you're
going to have an experience you pay
attention to what you're doing and you
repeat it over and over again Nerf cells
that fire together wire together you're
going to begin to install new circuits
in the opposite side of your brain
that's that's common you do the scan at
the end you see those actual physical
changes you take those people uh the
other group and you ask them to close
their eyes without lifting a finger have
the mental rehearse those scales and
Cordes and at the end of five days they
grow the same amount of circuits in
their brain as the people who actually
physically demonstrated the act in other
words they were so present with what
they were doing the brain did not know
the difference between the real life
experience and what they were Imagining
the brain was physically changing to
look like they already experienced it
