Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree . It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain.

How is split-brain syndrome treated?
Split-brain surgery, or corpus calloscotomy, is a drastic way of alleviating epileptic seizures, the occurrence of sporadic electrical storms in the brain. The procedure involves severing the corpus callosum , the main bond between the brain’s left and right hemispheres.

Where would a surgeon split the brain?
A corpus callosotomy is an operation that severs (cuts) the corpus callosum , interrupting the spread of seizures from hemisphere to hemisphere. Seizures generally do not completely stop after this procedure (they continue on the side of the brain in which they originate).
What happens if corpus callosum is damaged?
Lesions of any part of the corpus callosum might lead to loss of contact between bilateral hemispheres that cause mental disorders, pseudobulbar palsy, speech and movement ataxia .
What part of the brain is responsible for lateralization?
The best example of an established lateralization is that of Broca’s and Wernicke’s areas , where both are often found exclusively on the left hemisphere.
