Split-Brain Patient

Definition

A split-brain patient is an individual who has undergone a surgical procedure called corpus callosotomy, where the corpus callosum (the structure that connects the two hemispheres of the brain) is severed to some degree. This procedure is often done to reduce or eliminate severe epileptic seizures.

Analogy

Imagine if you had two chefs in a kitchen who are used to working together seamlessly, but suddenly a wall is put up between them. They can still cook, but they can't coordinate their actions as well because they can't communicate directly anymore. That's what it's like for a split-brain patient - both sides of their brain can function independently, but they have trouble integrating information.
