Can you remove part of your brain?

Yes, apparently it is, according to a new analysis that assessed brain health among six adults who had undergone a hemispherectomy as children.

The highly invasive surgery, which entails removal or severing of half the brain, had been part of a pediatric epilepsy treatment to reduce seizure risk..

How does the corpus callosum affect behavior?

Individuals with a disorder of the corpus callosum typically have delays in attaining developmental milestones such as walking, talking, or reading; challenges with social interactions; clumsiness and poor motor coordination, particularly on skills that require coordination of left and right hands and feet (such as …

What happens if corpus callosum is damaged?

What is the split brain experiment?

In the 1950s and 1960s, Roger Sperry performed experiments on cats, monkeys, and humans to study functional differences between the two hemispheres of the brain in the United States. To do so he studied the corpus callosum, which is a large bundle of neurons that connects the two hemispheres of the brain.

What happens if a person’s corpus callosum is cut or removed?

A corpus callosotomy is an operation that 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).

How long does a hemispherectomy surgery take?

The surgeon may remove some parts of the brain and disconnect other parts. The corpus callosum will be cut to prevent the spread of seizures to the functional side of the brain. At the end of the procedure, the skull will be replaced and the scalp will be sutured closed. The surgery takes about six hours.

How is a split brain operation different from a hemispherectomy?

Anatomical hemispherectomies involve the removal of the entire hemisphere, whereas functional hemispherectomies only take out parts of a hemisphere, as well as severing the corpus callosum, the fiber bundle that connects the two halves of the brain.

Can split brain patients drive?

Deep connections. Other researchers are studying the role of subcortical communication in the coordinated movements of the hands. Split-brain patients have little difficulty with ‘bimanual’ tasks, and Vicki and at least one other patient are able to drive a car.

What do split brain patients struggle with?

Many patients with split-brain syndrome retain intact memory and social skills. … For the same reason, the patient may have difficulty using the left hand to execute verbal commands; the inability to respond to commands with motor activity is a form of apraxia.

How does a person with a split brain act?

In patients with split-brain syndrome, the right hemisphere, which controls the left hand and foot, acts independently of the left hemisphere and the person’s ability to make rational decisions. … One of their child participants, Paul S., had a fully functional language center in both hemispheres.
