Why would someone get their corpus callosotomy split?
A corpus callosotomy, sometimes called split-brain surgery, may be performed in people with the most extreme and uncontrollable forms of epilepsy, when frequent seizures affect both sides of the brain.
What happens when you split the corpus callosum?
A cut corpus callosum can’t send seizure signals from one side of the brain to the other. Seizures still occur on the side of the brain where they start. After surgery, these seizures tend to be less severe because they only affect half of the brain.
What does severing the corpus callosum do?
Sperry concluded that with a severed corpus callosum, the hemispheres cannot communicate and each one acts as the only brain.
What is a corpus callosotomy surgery?
Corpus callosotomy is a surgical procedure used to treat atonic seizures, also called drop attacks, by dividing all or part of the corpus callosum. The corpus callosum is the bundle of nerve fibers that connects the two brain hemispheres.
What is a corpus callosotomy?
Corpus callosotomy is surgery to treat epilepsy seizures when antiseizure medications don’t help. The procedure involves cutting a band of fibers (the corpus callosum) in the brain.
Can a cut corpus callosum cause seizures?
A cut corpus callosum can’t send seizure signals from one side of the brain to the other. Seizures still occur on the side of the brain where they start. After surgery, these seizures tend to be less severe because they only affect half of the brain.
Where is the corpus callosum located in the brain?
The corpus callosum is a band of nerve fibers located deep in the brain that connects the two halves of the brain. It helps the hemispheres share information, but it also contributes to the spread of seizure impulses from one side of the brain to the other.
How is the corpus callosum cut in a stroke?
In the first operation, the front two-thirds of the structure is cut, but the back section is preserved. This allows the hemispheres to continue sharing visual information. If this does not control the serious seizures, the remainder of the corpus callosum can be cut in a second operation.
