Corpus callosotomy is a surgical procedure that involves cutting the corpus callosum, the bundle of nerve fibers connecting the left and right hemispheres of the brain. This operation is primarily performed to reduce the frequency and severity of seizures in patients with severe epilepsy, particularly when other treatments have failed. By severing the connection between the two hemispheres, the procedure can help prevent the spread of seizure activity. While it may not eliminate seizures entirely, many patients experience significant improvements in their quality of life and a reduction in seizure episodes following the surgery.
