Behavior After Split-brain surgery
Transcript of Behavior After Split-brain surgery
What Is Split Brain? Right Hemisphere: Is a condition resulting from surgery that isolates the brains two hemispheres by cutting the fibers connecting them.
The right hemisphere is responsible for focusing attention and perception. There are signifigent changes that happen to the left hemisphere after surgery like:
verbalization There are signifigent differences also in the right hemisphere like:
Not being verbal There has been alot of cases of unusual behavior with patients of Split-Brain studied by scientists. Two scientists, Roger Sperry and Michael Gazzangia were the first to study split-brain in people. One of their patients "Paul S." his right hemisphere was already more developed in language ability before his operation. This is uncommon but occasionally happens. The two scientists decided to interview both sides of his brain, they asked his right side what he wanted to be and he said automobile racer. When they asked his left side he said draftsman. This shows how independent both sides of the brain are after surgery.
