Question

Quizplus · Accepted Answer

Split-brain surgery involves severing the corpus callosum, which is the band of fibers connecting the two hemispheres of the brain. This creates two independent halves of the brain that can no longer communicate with each other. In Meri's case, it is likely that her right and left hands were acting independently, causing her to pick out different clothes with each hand and put them on. This is a common phenomenon after split-brain surgery.
