Although Peek did not undergo corpus callosotomy, he is considered a natural split-brain patient and is critical to understanding the importance of the
corpus callosum
.
Is split-brain genetic?
Developmental Split-Brain syndrome is
a genetic condition caused by mutations in the gene Deleted in colorectal cancer (DCC)
. DCC acts as a receptor for netrin-1 and, together, guides the developing neurons to cross the midline and form connections between the two halves of the brain.
Can you be born with a split brain?

Do people with split brains really have two minds?

hemispherectomy
is a rare surgery where half of the brain is either removed or disconnected from the other half. It’s performed on children and adults who have seizures that don’t respond to medicine.
What do split brain studies reveal?
For several decades, split-brain research has provided valuable insight into the fields of psychology and neuroscience. These studies have progressed our knowledge of
hemispheric specialization, language processing, the role of the corpus callosum, cognition, and even human consciousness
.
What are the side effects of split brain surgery?
- Loss of coordination or balance problems.
- More partial seizures on one side of the brain.
- Speech problems, including trouble producing speech (apraxia) and trouble speaking and comprehending (aphasia).
- Stroke.
- Swelling in the brain.
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
.
Why would someone have a split brain procedure?
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.
Can you survive without corpus callosum?
While
not essential for survival
, a missing or damaged corpus callosum can cause a range of developmental problems. It’s thought that one in 3,000 people have agenesis of the corpus callosum—a congenital disorder that sees a complete or partial absence of the conduit.
