Split Brain: - A tale of two halves      Aug 6 2013 4:48AM
Slides Blog

Brain, the central part of the nervous system is found in both vertebrate and non-vertebrates. It is the largest and most complex organ that is made up of more than 100 billion nerves that communicate in trillions of connections. The brain is made up of many specialized areas that work together. However, basically it is divided into two halves by a longitudinal fissure that creates two distinct cerebral hemispheres. These hemispheres of the brain are connected to each other with a very large bundle of nerve fibers known as  corpus callosum. Though these hemispheres are roughly the mirror images, they have a subtle difference between each other.

It is commonly known that the right hemisphere of the brain controls the left side of the body, and the left hemisphere controls the right side. Corpus callosum severed to some degree causes the disruption or interference with the connection between the hemispheres of the brain. This condition leads to the problem of Cluster Partition which in layman term is known as split brain. It is the condition where each side of the brain believes that the other is dead, and thus proceeds to overtake all the resources.

To understand the condition more clearly, it is important for you to know about Seizure. An abnormal discharge of electrical impulses within the brain creates Seizure. Rather than smooth constant production of Action Potentials, neurons fire without any regulation, causing disruption to brain function at the biochemical level causing  Head Injury Fever, Neurological Defect, Sepsis, Brain Tumor Stroke Epilepsy. Risk of epilepsy is greatest in early childhood and late adulthood.

There are 3 major courses of treatment for Epilepsy where drugs generally act as the first line of attack because it is effective, relatively inexpensive, and safe. Doctors usually as the patients to go for Ketogenic diet where the patient has to intake lots of fat and almost no carbohydrates. The surgical operation called corpus callosotomy, is usually used as a last resort by people to treat refractory epilepsy.
