The Human Brain Essay - 1341 Words

Our brains weigh about three pounds and are divided into two similar looking but functionally different hemisphere, the right hemisphere and the left hemisphere. Both of which are connected by a large bundle of nerves called the corpus collosum. In some people with severe seizure disorders such as epilepsy, it was found that if this bundle of nerves was severed their seizure would either cease or a the very least be better controlled. From this surgical procedure it was discovered that the two hemispheres had different methods of processing information, as well as controlling parts of the body. The left hemisphere controls the right have of the body and the right hemisphere controls the left side. While we rely on both hemispheres to†¦show more content†¦Interestingly enough, the centers for speech interpretation and production are located in the left hemisphere. If the patient is blindfolded and a familiar object, such as a toothbrush, is placed in his left hand he appears to know what it is; for example by make the gesture of brushing his teeth. If asked by the experimenter to name the object he can not. When asked what he is doing with the object, gesturing a brushing motion, he has know idea. If the left hand gives the toothbrush to the right hand, the patient will immediately say quot;toothbrush.quot; Cutting apart the two hemispheres of the human brain is a drastic step, and is one of the most controversial operations ever performed. Controversy stems not from the risk to life the procedure involves. It stems from a Jekyll and Hyde aura surrounding the side effects-thequot;Split-Brainquot; syndrome. They orchestrate into a single personality if-and only if-the cerebral hemispheres communicate. Thus, many neurosurgeons have been reluctant to try the split-brain operation for fear of severing all vital communications. However, there may now be a way to avoid the Jekyll-Hyde effect. A new form of the surgery devised by P.J. Vogel called anterior cerebral commissurotomy eliminates the Jekyll-Hyde effect. The procedure involves; opening the skull, laying back the brains coverings, then using a tool called a cerebral retractor to expose the corpus callosum. The front three-fourths of the corpus callosum areShow MoreRelatedHuman Brain And Human Brains1477 Words   |  6 PagesWe, the human species are unique. This is a phrase we all have heard at some point in our lives. We are unique compared to other animals in our language, movements, and emotions. We have our own language which the majority of animals do not, we stand on two legs while the majority of the animals are on four legs, and we are much more sensitive to our emotional reactions, making us complex animals. Now, where does all these differences come from?

The Cerebrum, also known as the Cerebral Cortex, is the largest part of the human brain. It is divided into four parts that are called â€Å"lobes†: there s the frontal lobe which is linked with reasoning, planning, parts of speech, emotions, and problem solving- the parietal lobe which is linked to movement, orientation, and recognitions- the occipital lobe which is linked to visual processing like objectRead MoreThe Perception Of The Human Brain s Brain953 Words   |  4 Pagesreason: survival†¦ as deep in the brain†¦we got special cells known as mirror neurons† (H.

For example, individuals that are into Football will get worked up from just watching it due to similarly reacting to the responses of t he actual audience at the game. The reason as to why is because of the outcome of the human brain’s premotor cortex initiatingRead More The Human Brain Essay1189 Words   |  5 PagesThe human brain is a big, intricate—yet delicate, structure in the human body. It is the key structure in cognitive function. Any damage to the brain does not only â€Å"erase† memories but also may â€Å"deceive† the brain to erroneously remember a new object as being familiar (2010). The innovative researchers at Cambridge University investigated this phenomenon in their research on The Paradoxial False Memory for Objects after Brain Damage. The publication began by stating the widely acceptable premiseRead MoreStress And The Human Brain1720 Words   |  7 Pagesof study for those interested in human sciences. In particular, stress is often viewed through the scopes of a Psychologist, Sociologist and an Anthropologist. The Psychologist s perspective revolves around relations between stress and the human brain. One of the questions they might ask would be if an individual can be born with stress. The answer is sometimes but not often.
