How To Severe Epilepsy

Good Essays
AIMS The following questions have to do with the study of patients who have undergone a surgery (for medical reasons, severe epilepsy being one) that severed the corpus callosum. This leaves the two halves of the brain to work independently from one another. The main questions this study seeks to answer are: how do the two halves of the brain interact with each other and how is this relationship altered after the subjects have undergone this surgery?
METHODS
Basically, subjects were asked to attempt modest tasks that were presented to only one side of the brain at a time. Many of the experiments involved different variations of visual cues. For example; lights, pictures and flash cards were all used; most in conjunction with tasks such

In the simplest experiment a light bar was set up and the subject was asked to focus in the center of the light bar. When all lights flashed the subject could only testify to registering the right half of the lights and when just the left side was lit no register of any lights being lit was recorded by the subject. Often an object would be shown to a subject in one field of vision and they would recognize and describe the object; when the same object was shown to them in the other field of vision it appeared that the subject had never seen nor heard of such an object. When a subject’s right hand held an object, they could acknowledge through writing or verbally what it was but not if placed in the left hand. If asked to find, with their left hand, a specific item from a group of items held from view, the left hand had no trouble recognizing the requested item. Many similar experiments were conducted.
DISCUSSION
The study definitely proves that the two halves of the brain require the corpus collosum to be intact in order for them to communicate successfully. The study also shows that I.Q., temperament and personality are not altered after surgery, which leads one to believe that the corpus collosum is not responsible for these characteristics, but that it is responsible for translating the perception of incoming information being filtered visually and physically.
CRITICAL

There is one cool concept that is expressed at the end of the article, that is; knowing that the two halves of the brain can function and even develop independently would it be possible that if the corpus collossum were severed during early childhood the two halves of said child may develop as if each were whole? This is an interesting question. I imagine that if this were the case the corpus collosum would have already began to physically fade away into evolutionary history and that would be that. So for now I will be thankful my two halves are bonded, while sufferers of epilepsy can be thankful for an option to divorce the two halves and psychologists can enjoy a controversially free study of

    I observed two different cases during my operating room experience. The first case I sat in on was a bi-CABG surgery, which stands for Coronary Artery Bypass Grafting. A CABG is a type of procedure that is done to improve the blood flow to a person’s heart. The second procedure that I got to sit in on was a laparoscopic hiatal hernia repair. A hiatal hernia is when a part of a person’s stomach pushes through the small opening of the diaphragm and into that person’s chest area.…

    2 a. They generally suffer from severe epilepsy and to reduce the severity of the seizures, as a last resort, a surgical operation is performed to sever the corpus callosum either partially or completely. Because of this, the patient essentially has two different brains such that the two hemispheres are isolated preventing intercommunication as well as the spread of the seizure to another hemisphere. 2 b. Hence we can observe that language is predominantly lateralized to the left hemisphere.…

    Gene Therapy Cons

    Walters and Palmer believe that genetic treatment may be the only way to avoid many genetic disorders for some people. When an embryo undergoes germ-line therapy early enough, the embryo has a great potential to prevent irreparable damage to the developing embryo and thus be disease free. However, it then causes all cells of the embryo to be genetically modified. Germ-line therapy, as previously stated, prevents the transmission of genetic diseases through the generations, unlike somatic cell therapy. It is then more efficient to undergo germ-line therapy than somatic cell therapy.…

    The leading experts in the field, including pharmacologists and psychiatrists are adding their voices to the movement. Placebo effects have been highly researched and a recent study demonstrated how the power of belief, an important component of the placebo effect, affects the areas of the brain that are considered to be activated during addictive behaviors. The reasons are quite simple. First, placebos are demonstrated through empirical evidence to have no real effects on the conditions that they are given for. This in turn can lead to do no harmful effects to the user than to offer more extreme treatment.…

The conceptual purpose behind face reading was to create a science out of a frequent human action: judging a person by his or her facial characteristics. Modern research shows when a person observes the face of another for the first time, a judgement of character is formulated not the distinctiveness of a person. Likewise, the reading of your rump has no actuality that can describe your personality or…
