The Split Brain Procedure - 2384 Words

Our brain is divided into two halves or hemispheres. The left hemisphere specializes in language, words, understanding and reasoning while the right hemisphere is associated with spatial awareness and creativity. Split brain is a term used to describe the result when the corpus callosum connecting the two hemispheres is severed either partially or completely. Before the proceeding with the surgical procedure, the patient’s head is either partially or completely shaven in order to gain easier access to the scalp. Once they are under general anesthesia, the surgeon makes an incision, which allows for a craniotomy to be performed. A craniotomy is an operation that allows for the temporary removal of part of the bone from the skull to expose the brain. For a partial callostomy, the anterior two-thirds is sectioned, but the posterior one-third is sectioned as well for a complete callostomy. After sectioning, the dura is closed and a portion of the cranium is replaced. The split-brain procedure was primarily done in order to stop epileptic seizures. Epileptic episodes can range from a short loss of consciousness to severely thrashing arms and legs uncontrollably. Scientists and researchers are now aware of the fact that seizures are caused by an abnormal discharge of electrical impulses throughout the brain that interrupts normal brain patterns. They were also able to figure out that severing the corpus callosum prevents the electrical discharge from dispersing through theShow MoreRelated The Human Brain Essay1341 Words   |  6 Pages 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 b e better controlled. From this surgical procedure it was discovered that the two hemispheresRead MoreHistory Of Split Brain Research982 Words   |  4 PagesSplit-Brain Research History of split-brain research Walter Dandy, an American neurosurgeon unintentionally paved the way into research on split-brain patients in the 1930s. Split-Brain refers to patients who have had their corpus callosum severed to some extent or in whole. This procedure was mainly used as an extremely invasive surgical procedure within patients suffering from intractable epileptic seizures. The corpus callosum consists of over 200 million nerve fibres connecting the left andRead MoreSplit Brain1201 Words   |  4 Pagesï » ¿Running Head: SPLIT BRAIN LATERALIZATION Difference of Lateralization Between Split Brain And Intact Brain Patients Psychology 102 Section 6X Student Abstract Split brain patients lateralize functions in their brains to either side of the brains while intact brain patients utilize both sides of their brains. A group of 20 subjects were tested, 10 split brain and 10 intact brain patients. We gave these subjects three exams, a vocabulary test, a logical reasoning task and a faceRead MoreThe Theory Of The Mind Becomes Of Critical Importance860 Words   |  4 Pagesentity compared to the physical neurons within the brain. However, the field of neuroscience is finding many connections between the physical nature of the brain and the supposed non-physical aspect of the human mind. In a sense, neuroscience seeks to understand the functioning of the mind in terms of the physical neuronal firings of the brain. In addition, neuroscience seeks further information concerning the â€Å"fixity† and â€Å"plasticity† of the brain. The field of neuropsychology was developed in responseRead MoreSchizophrenia, By Swiss Psychiatrist Paul Eugen Bleuler1182 Words   |  5 Pages Schizophrenia, known as the brain disorder in which people interpret reality abnormally is a serious brain disorder. Schizophrenia can distort the way you think, expression emotions, act, and affects the way you react to others. Sufferers also have issues functioning at work, in school, in their relationships, and of course, society as a whole. Schizophrenia, thought as the most debilitating of the mental illnesses, is a life-long disease. Schizophrenia can only be controlled through properRead MoreBrain Asymmetry Experiment1217 Words   |  5 PagesDistinctiveness between the right and left hemisphere of the brain Word Count: 995 Abstract The brain assymetry experiment is to investigate on the distinctiveness of the right and left hemisphere in the brain as each hemisphere has certain specializations. The experiment were carried out by initially asking the 25 participant on whether they were left or right handed and they had to choose the chimeric image which appeared younger to them. Laterality quotients were calculated in order toRead MoreFunctions Of The Various Cerebral Cortex Regions Essay1662 Words   |  7 Pagesa damaged brain reorganize itself, and what is neurogenesis c.

This is where the brain stores everything one remembers. The hippocampus is also responsible for a part of memory. This is where the process of new memories is introduced into long-term storage. If the hippocampus is damaged or absent, one would not remember what is happening in the present, but only remember what happened in the past. It’s in the frontal lobe that memory is recalled - this is where the brains explores and recalls important information. In thisRead MoreSplit Brain: What Happens when You Have Two Brains?570 Words   |  2 Pageswould have a split brain, I don’t believe I would act any differently than I act now.

As defined in our cognitive psychology book free recall is a procedure for testing memory in which the participant is asked to remember stimuli that was previously presented (Goldstein 7). Cued recall is defined as a procedure for testing memory in which a participant is presented with cues, such as words or phrases, to aid recall of previously experienced stimuli (Goldstein 7).
