What was the logic behind the first experimental split-brain operations on humans?
A) Removing the precise brain location where epileptic seizures originated should stop the seizures.
B) Selectively removing portions of the left hemisphere should shift language functions to the right hemisphere.
C) Cutting the corpus callosum should contain seizure activity in just one hemisphere of the brain.
D) Cutting the corpus callosum would force the brain to use the left and right hemispheres for different functions.

Question

Quizplus · Accepted Answer

The logic behind the first experimental split-brain operations on humans was to contain seizure activity in just one hemisphere of the brain by cutting the corpus callosum, which is a broad band of nerve fibers that connects the two hemispheres of the brain. By doing so, seizure activity is limited to just one hemisphere, which can reduce the severity and frequency of seizures. This technique has since been refined and is still used today as a treatment for severe cases of epilepsy. None of the other options accurately describe the rationale for the first split-brain operations.
