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 ...Download file to see next pagesRead More

Neuropsychology paper on Split Brain
...separately. Like the Earth, the brain is divided into two hemispheres: the right and left hemispheres. They are as much independent as they are intertwined. Researchers and psychologist hypothesize that the division of the two hemispheres makes them more like two minds rather than one. Research has shown that the left hemisphere is more dominant and responsible for processes involving language whereas the right hemisphere is designed to process spatial relationships. This has been proven through experimentation as well as natural medical phenomenon. When a person has a stroke and it impacts an area of the brain, it is observed that functioning that is associated with...

Split Brain/ Reflection
...? Split Brain xxxxx School: xxxxx xxxxx xxxxx Introduction: The brain is divided into two parts, the right and left hemispheres. Both of these hemispheres look like a mirror image of one and other. However, it has been validated that the left one is always bigger than the right one. 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. However, in some of the left-handed people, the speech centres location is the...

...in areas that have been damaged. There were little functional plasticity recorded in beats or partial callosotomies but much of plasticity can be observed in children patient getting hemispherctomy, which indicates that the opposite hemisphere can cope up with some functions that were initially performed by its opposite hemisphere. Memory of the split-brain patient tends to be lower than normal though better than in patients suffering from amnesia indicating that the brain is responsible for formation of some types of memory. It showed that posterior callosal which incorporates hippocampal commisures leads to mild memory loss....

The Brain and its Functions Regarding Disorders
...? The Brain and its Functions regarding Disorders The Brain and its Functions regarding Disorders Epilepsy is a neurological or disorder of the brain which is characterized by brie recurrent disparities in the electrical action of the brain. The periodic changes in electrical impulses within the brain lead to a culmination of seizures which may be mild or severe and last for a few seconds to several minutes. In the case of an epileptic spasm the cells within the brain are activated rapidly beyond their normal functioning rates. For instance, during a partial convulsion of epilepsy, only a...

...reservation regarding any aspect. For instance, when a person first encounters a new species of bird, many processes start functioning simultaneously, and are destined to target different areas of the brain that interconnect via adjacent neurons to form a new neuronal circuit concerning the recognition of that bird. Eyes perceive all the dimensions of the bird’s appearance; its color, shape of beak, eye, and its size. All this information is conveyed via the optic disc tract to the visual cortex of the brain for the formation of complete picture of the bird. Side by side, auditory cortex notes the voice and name of that bird. On second exposure with the same bird...

Psychology- The split brain
...Section a. What do you think this article got right about the topic? This article covers the theory of half-brain and how effective it is to use only a part of the brain (Nigel). One of the things that the article got right about the topic was that people use one half of their brains more than they use the other. This is true since research has shown that most people only develop the use of one part of their brains while the other half is left unexploited. The article is also right in stating that split brain surgery is normally done to control violent seizures. Only the part of the brain where the seizure is coming from...

Brain vs Left Brain Learning
...Right Brain vs. Left Brain Learning Introduction: The brain is the most complex organ in a human body and various aspects of its function are still a topic of research and constant debate. However, many authorities agree that two hemispheres of the brain are capable of thinking in separate directions. The recent work of Roger Sperry in his research of “Split Brain Theory” has fascinated many researchers around the world. He received a Noble prize for his work in 1981. In his Nobel speech, he mentioned that the same individual is capable of exhibiting two distinct forms of mental approach and strategy, just like two...

...Psychology What are two kinds of evidence that consciousness depends on a functioning brain? To start with, damage to the alerting areas of the brain, the brain stem and the midbrain, most likely can result to loss of consciousness. The first evidence is that consciousness cannot exist without the cortex working accordingly. Without this part, it would not be possible to comprehend speech, plan, move, solve problems, or express emotions. All these are aspects of consciousness. Second evidence is the brain stem. The hypothalamus is responsible for the sleep cycle; therefore, the suprachiasmatic nucleus controls the preoptic nucleus that...

Left brain vs right brain thinking
...Left Brain vs Right Brain Thinking Teacher               Left Brain vs Right Brain Thinking Is it important to know whether one thinks with his right or with his left brain? Although scientists have various opposing views on this theory, it is important to know whether distinction between the two brain hemispheres really makes sense, and if so, then for what purpose is it? So far, there is no direct evidence pointing out to distinct left and right brain functions, except that identification of right and left brain dominance may be helpful in the field of education. According to Hellige...

Brain Functions in Depression
...circuitry where the hippocampus and amygdala are found. The functional neuroimaging studies support that depression is due to decrease metabolic activities in neocortical structures, therefore increasing metabolic activity of the limbic structures. The need to determine the part of the brain that is abnormal during depression led to scientists and neurologists use positron emission tomographic images (PET). They discovered that the prefrontal cortex had abnormally diminished activity with patients suffering from unipolar depression and bipolar depression (Farooqui, 2010). This region controls emotional responses and connects to other areas of the brain. The...
