KOCH: An operation done by a neurosurgeon here at Loma La Vista Hospital called Joe Bogen, he did what’s called a “split-brain surgery”. So in some people that have very bad epileptic seizures, what happens and, let’s say, a seizure – a seizure, which is just electrical malfunctioning of the brain, so it’s initiated in one part of the brain and then spreads across to the entire right hemisphere.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
