It also tends to create a coordination of the two hemispheres for activities that need the combined function of both the parts of the brain (Clark et al 2010).
The term split brain is used for those patients whose corpus callosum has been removed for the treatment of conditions like epilepsy to stop the extending of the condition from one cerebral hemisphere to the other cerebral hemisphere. This operation led to the proving of different functions of the corpus callosum and these patients presented with interesting findings. The split brain patients live normal lives like other individuals and could carry out activities like other people but there are certain changes seen in these people. It is seen that when these patients see something which is only restricted to their left visual field they are unable to name it. They are aware of what that thing is and they can also feel it. The reason for this is that the connection between the two hemispheres is lost and information cannot be relayed from the right hemisphere to the left hemisphere which is principally responsible for language. It also proved the fact that “spatial tasks” are performed at a more optimal level by the right hemisphere. This was seen when the patients were asked to collected colored objects. They could perform this activity in a better way with the left hand. An intriguing aspect seen in these patients is that the two hemispheres function as two brains (Greenstein et al 2000).
I think split brain surgery should only be performed as a last resort when all other measures have failed for the treatment of conditions like epilepsy and other conditions. This surgery proves to have dramatic results but it does produce alterations in the normal brain

As the author of the essay puts it, the split-brain patient’s two hemispheres are separated in that their left hemisphere does not recognize what the left hemisphere is doing. Notably, each hemisphere functions differently since it is conscious of its own, and both the right and left hemispheres may be conscious simultaneously distinct.
The paper focuses on epilepsy, which develops due to abnormalities in the wiring of neuron and sensory nerves leading to imbalances in the nerve signaling moiety known as neurotransmitters. Additionally changes in features of the brain cells termed as channels or a blend of both factors may lead to epilepsy.
First of all, aphasia usually refers to lesions of affectations of the frontal, temporal, and parietal lobes of the brain which are areas concerned with the ability to produce and comprehend language (Masdeu, 2000). Aphasia also refers to difficulties of a person in remembering words, as well as their inability to speak, read, and write (Masdeu, 2000).
This anatomical difference is because of the different functions these two spheres perform. The left hemisphere is used for language; where as the right side is specifically used for mental imagery as well as understanding the spatial relationships. Use of sound and speech are mostly located in the left hemisphere.
The fundamental units within the brain are neurons. These cells have special properties and organelles, which are specifically used for neural communication with organs and other parts of the body via the secretion of neurotransmitters, which is made possible by an electrochemical signal that is sent via the depolarization/repolarization of neurons.
As it not only affects the cognitive processes but also the body leading to partial or full functional disability.
The behavioural outcomes of such an injury are not predictable as they vary from person to person. It also depends on the degree of functioning prior injury along with the location of damage in the brain of the injured.
An example related to lifestyle has been given whereby two populations of the elderly were studied by researchers. The tow population included sedentary and active. The findings were that the cognitive was greatly influenced. Exercise was observed to influence executive function positively and quantitative skills were positively affected.
On the other hand, the brain of adults do not consume a lot of energy since the body uses most of the energy to enhance higher body growth since the brain is fully developed during adulthood.
Sleep is always
Autism as a development disorder is thus used by Baron-Cohen as a reference point in his research on the extreme male brain theory. For Baron-Cohen to say that there is a ‘male brain’ therefore simply means that the male and female are not the same in terms of the structure and functions of their brains (Auyeung et al., 2009).
