The Human Brain Essay

It is still not fully understood whether or not the action of certain tasks is actually dependant on both of the brain hemispheres, because they both appear to have control over some tasks. An example of this, is the left hemisphere which is said to be responsible for the analytic part of the tasks, such as reading and making calculations. Within many individuals, it is also the dominant centre of language

“The Human Brain”, by myPerspectives, is an informative article that claims that the brain is a complex organ that is truly impressive. The brain is a key part of the central nervous system, that controls the entire body’s activities, to simple things such as breathing. These actions are fired through neurons, that quickly travel through the spinal cord. Surprisingly, the brain transmits these messages at an unimaginable rate, at 150 miles per hour, through 85 billion cells, called neurons. These neurons can form up to 10,000 synapses, or connections to each other. By itself, the brain can create billions of synapses, which change the structure of the brain every time new information is learned. However, there is still much that scientists

I started my education in Erie, Pennslyviana.I attend McDowell High. I would say that we were one of the richer schools were I live. I am going to talk about my first assignment Brainology. I thought it was very interesting and it thought me a lot about how some people have different mindsets.

The purpose of this paper is to evaluate the correlational method as a means for examining the relationship between functions of the left and right hemispheres. I will compare the performance of people with intact brains with the performance of so-called split-brain patients. In many ways, the brains of these two groups are very similar. 1a. The brain stem is found in the deepest part of the brain. The brainstem controls the automatic survival functions of the body, such as breathing. There are no differences between the function of the normal brainstem and the brain of a split brain patient. The brainstem will still supply the automatic survival functions of the body. 1b. The hippocampus is found in the limbic system along with the amygdala, the hypothalamus. The hippocampus is in charge of allowing the body to process information into memories. Without the hippocampus, there is no way for new memories to be created. There is no anatomical difference between the hippocampus in the normal brain and a split brain. 1c. The corpus callosum is found in the center of the brain. The role it plays as a part of the brain is it connects both the left and right hemispheres of the brain, allowing them to work and interact together as a whole system. The difference between the anatomy of the corpus callosum in a split brain patient versus someone without a

* In split-brain surgery the bundle of fibers that connects cerebral hemispheres (the corpus callosum) is cut to reduce the severity of epileptic seizures.

Numerous researches and experiments have been done based on whether the human being possess one brain divided into two parts (left and right hemisphere) or whether we have two different brains working together. The psychologist Roger W. Sperry was the first on research this topic with some experiments on animals. Then, he later started working with Michael Gazzaniga. They were able to find split-brain patients. Those patients had their brain split as way of reducing or stopping uncontrollable epilepsy. Many agreed to participate in the experiments. The experiments that they held focused on finding out what kind of limitations would each brain have if they operated independently, how the 5 senses

As a student of psychology I have read about this procedure a few times during my studies. It seems possible that the doctors who performed this type of surgery may have been more interested in stretching the boundaries of medicine and gaining notoriety versus the actual care of the patient. The term psychosurgery describes a surgical intervention to change another person’s mood, thoughts, or behavior. This procedure was coined the frontal lobotomy. The procedure involved cutting the major connections between the prefrontal cortex and the rest of the brain. Lobotomies became part of a new age treatment for neurological diseases in the early 20th century. The original procedure, also known as a leucotomy, involved an injection of alcohol into

Over the years, brain surgery has evolved substantially. Looking into multiple types of surgery, surgery is able to be quite unusual. Humans will cut into each other a lot of times in order to get rid of deadly disease and even just to remove excess body fat. The reality that we do not marvel about these on a daily basis shows how advanced surgery has grown over the years. Surgery is a safer and more reliable tool including a necessary component of health care. Previously, the surgeries themselves were brutal from lack of understandings toward anesthesia and none of the tools accessible today with operations forced and traumatic. With the present tools through surgery, brain surgery has changed greatly. This article chosen was aligning with

Yarnell’s response to her friend made me stop and think if it is just that simple, to think differently. When I get stressed out over something and let my emotions take over I usually just let them control me. Now after hearing Dr. Yarnell, every time and become emotional I am going to remind myself to just move into the left side of my brain. Hopefully by doing that I will be able to think more logically. I have heard of this concept before, but I did not have a full understanding on what it really meant. I thought that when some one said you were left brained or right brained, it was just a silly saying. I found it very surprising that it is actually a true concept. I is really amazing how the brain works and the many different functions of it. We discussed many other parts of the brain and how they work also. I just found that when discussing the brain, most of the parts were not as interesting as the two hemispheres. After class, I actually went home and used the terms of the hemispheres all night on my parents. My mom is a psych nurse so she understood, but when it came to my dad, it took a lot of explaining. After a few attempts, he was able to understand how fascinating the brain really can

This surgery was founded by Portuguese doctor Egas Moniz. He learned of two Chimpanzees who had their frontal lobes removed in order to change their emotions and actions. So he came up with the idea that this must be tried on humans with mental disorders to see if it can cure them. A separation tool was made and Dr. Moniz began doing frontal lobotomies at the “Libson Insane Asylum” (Harriet Hall 2015.) Dr. Moniz began to notice that his patients began to act “more docile and seemingly content” (Harriet Hall 2015.) These actions were complete opposites from their original actions of rage and violence. So without any further studies Dr. Moniz would publisher his work winning him a Nobel Prize in medicine and he became critically acclaimed with this work. At the time the Nobel Prize committee claimed it to be “the most important discovery ever made” pertaining to psychiatric therapy (Harriet Hall 2015.) due to its limited time of research the horrible side effects were never addressed till after the multiple procedures were done. The case of Bennie Sternberg being a prime example. Bennie suffered from schizophrenia and would sometimes act out in fits of anger. The Sternberg family was more or less pressured into having Bennie go through the surgery. Post-surgery Bennie was not the same. His family would account that Bennie “did not speak a word” he would “barely move” (Harriet Hall 2015.) He

Lobotomy, a surgical procedure that which involves the incision of the prefrontal brain; To cure patients suffering from mild to critical mental conditions. The article reported by NPR portrays the role of lobotomy and it’s effects based upon the point of view of actual patient, Howard Dully. Originally, Freeman adapted the idea of neurological procedures from Portuguese neurologist Egas Moniz. Who infamously drilled holes into patients skulls to cure mental illness. From this idea Freeman adapted the term lobotomy and later performed the first ever American lobotomy procedure. And due to lack of the understanding and treatments for mental illnesses this surgical procedure spread like wildfire in the United States.

The results of this study show us the brain is not in fact symmetrical and the two hemispheres in the brain work in different ways. The left hemisphere is known to play the dominant role, which is in control of all complex behavioural and cognitive processes as for the right hemisphere it only plays a minor role. This report will further analyse how different the two hemisphers is the dominant side of the brain.

By conducting Corpus Calloscotomy, also known as “Spilt Brain Research” which is a drastic way of alleviating epileptic seizures, which are the occurrence of sporadic electrical storms in the brain. Although during research on people with a severed corpus callosum, researchers have confirmed that the majority of the research subjects have revealed that the right hemisphere of the brain is directly related to the visual recognition and identification of emotion, whereas the left hemisphere is directly related to the verbal aspect and functionality. After the split brain surgical procedure the two hemispheres do not exchange information as well as they did initially. The damage can also result in split brain syndrome, which is a condition where

By eliminating the pathway of communication between the hemispheres, a seizure can be kept from spreading. The procedure is called Corpus callosotomy, two-thirds of the anterior CC is sectioned off for a partial callosotomy; one-third of the posterior is sectioned for a complete callosotomy. The complete callosotomy of the CC is know as a split-brain procedure. By severing the communication of the hemisphere, both will have its own impulses; acting as “two brains” in one body. However, a split-brain procedure is dangerous and most doctors recommend a partial callosotomy then the complete split of the brain. Other diseases such as Alien hand syndrome (AHS) and Agenesis of the corpus callosum (ACC) can occur due to damage in the CC. Alien hand syndrome is the involuntary movement of a persons hand without their awareness and a lack of control over the action. ACC is a birth defect due to the absence of the corpus callosum. This occurs if the CC fails to develop normally between the third and twelfth week of pregnancy. This can lead to vision impairment, poor motor control, low perception of pain and difficulty chewing and

While studying epilepsy, Roger Sperry found that cutting the corpus callosum, which connects the two parts of the brain, help reduce seizures. However, patients who had the corpus callosum cut, reported having organizational and spacial problems. He discovered that while both sides of the brain were separated from each other, they continued to run, however were independent of each other. While conducting his experiments on the patients, he found that the left-side of the brain was used to process language. Sperry believed that the right brain was best at creative and intuitive activities, while the left brain worked better with critical thinking and logic. Today, we have found that people use both sides of the brain together to complete tasks,
