Last week we talked about concussions in our class. Namely, what
they are and what causes them. The latter question is easy
enough to answer, turn on any high contact sport and odds are
you will likely see an athlete receive a concussion. Yes this
massive deceleration that is experienced by our brains within
our skulls creates enormous stress on the nerve cells within the
brain. Basically what happens is that after the brain suffers an
injury, the nerve cells within our brains lose their
polarization. This polarization is necessary for bodily function
as signals are carried most effectively by electrical impulses
which are enabled by said polarization. Now in order to
counteract this depolarization the cells use a pump on their
outer surfaces which allow the transfer of charged ions to into
the cell. The only problem with this is that they need energy in
order to function, and after the brain suffers a collision blood
flow into the brain is significantly reduced. This means that
nutrients normally being carri
