The Split Brain: Some Thoughts
"Left, right, left, right--the marching song of the two-mind movement. To hear them talk, you'd think that everyone had a second mind, suppressed by the first. That the vocal left brain dominated the poor artistic right brain. Preventing it from getting a creative thought in edgewise. Soon there will be a consciousness raising movement: Stop referring to the left cerebral hemisphere as the "dominant" one. Invent a more egalitarian term like co-chairperson. Co-chairhemisphere?" William H. Calvin, "Left Brain, Right Brain: Science or the New Phrenology."
The brain is separated into two hemispheres in your brain, the right and the left. At first glance these hemispheres appear to be mirror images of one another, but on closer observations the two hemispheres have highly specialized regions that serve differing functions (1). In general, the right hemisphere interprets information and controls actions of the left side of the body. The left hemisphere interprets information and controls actions of the right side of the body. A thick band of fiber called the corpus callosum connects the two hemispheres. Evidently if the connection between the hemispheres is severed, a once common practice to relieve epileptic attacks, sensory information cannot pass to the correct region of the brain in order for a corresponding response to be made (2). Thus, your brain is SPLIT...!
To me the split brain theory seemed a bizarre notion. Isn't my brain a whole- controlled by the centrally located "little man" who receives my thoughts, processes and multiple functions of my brain? If this is true how could the brain be split into two? Do you have two "yous" then?
The split brain effect was first discovered by Roger Sperry and Ronald Meyers in the early 1960s (3). Meyers and Sperry showed that when the cat had its optic chiasm and corpus callosum severed, two independent learning centers were established - one in each hemisphere of the cat's brain. If the cat had its right eye open and its left eye covered and learned to make a simple conditioned response, it was unable to make the same response when the right eye was covered and the left eye was open. It was as if the learning was unable to be communicated to the other side of the brain (2); thus, it was obvious that information available to one side remained off-limits to the other.
The concept about the split-brain cases is two hemisphere separate apart, where means the left side focus on the left side, the right side focus on the right side (Parfit 378). He thinks that the concept of the split-brain and the normal brain are both true. Parfit denies that there are no person involved, also the ego theory doesn’t exist. He believes that once the brain has split apart, it has two separate streams of consciousness (Parfit 378). So, he claims that instead of asking “what happened to the original self?,” he says there is no ‘self’ (Parfit 379). Even though there are different events happened at the same time, that is not equal to different egos. “There are not here two different possibilities, one of which be true. These are

Today there is a life sized statue of Crump in Overton Park, a hospital, and a street named after Crump. No matter what you think about Crump, his legacy is cemented in the history books as one of Memphis’s most important political figures.
Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Hypertension is another term used to describe high blood pressure. This common condition increases the risk for heart disease and stroke, two leading causes of death for Americans. High blood pressure contributed to more than 362,895 deaths in the United States during 2010. Approximately 67 million persons in the United States have high blood pressure, and only half of those have their condition under control. An estimated 46,000 deaths could be avoided annually if 70% of patients with high blood pressure were treated according to published guidelines (Patel, Datu, Roman, Barton, Ritchey, Wall, Loustalot; 2014).
The National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health can also provide information about high blood pressure and its treatment. Visit their Web site at http://www.nhlbi.nih.gov/.
In 2003 The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) was released. Since then, it has become the most widely accepted guidelines for managing hypertension and is the guideline that i...
“Right-brained” or “left-brained” is a concept that has been manipulated by the media, it’s not supported by solid science. The myth of a “right-brain” person is generally creative, intuitive, artsy, while a left-brain person is more of a problem-solver, more direct, logical. Somehow the real meaning was lost in translation, so I’ll explain. The brain is divided into two sides, called hemispheres. The left hemisphere
Hypertension is a disease that effects a third of all Americans (American Heart Association [AHA], 2013, p. 1). The American heart association expects the number of patients living with hypertension to continue to rise (AHA, 2013). Reversing this trend will be of vital importance to the health of our population. Several factors influence hypertension, including access to primary preventative care, the availability of medications, diet and exercise control, diet modifications, and self-care are required to mitigate the effects of persistent hypertension on the body.
Living in the medieval time period was not as glamorous as it is often portrayed; peasants and serfs led hard lives, however, kings, lords, and knights lived lavishly and at the expense of those under them. In this paper you will read about all of these lifestyles, as well as the castles in which these lords and kings lived in. Mainly castle designs, fortifications, and siege tactics will be revealed to you; yet there are several sections, dealing with the lifestyles of the above mentioned, leading up to that.
Nowadays, it is widely known that the right and left hemisphere have different functions. The two hemispheres are equally important in a daily life basis. Nevertheless, in the 1960’s this was not common knowledge. Even though today the importance of the brain hemispheres is common knowledge, people don’t usually know to whom attribute this findings. One of the people who contributed to form a more defined picture about the brain hemispheres and their respective functions was Roger Wolcott Sperry, with the split brain research. Roger Sperry did more contributions than the split brain research, but this is his most important and revolutionary research in the psychological field. Thanks to the split brain research, Sperry proved that the two hemispheres of the brain are important, they work together and whatever side of the brain is more capable of doing the task is the hemisphere that takes the lead.

The chosen articles will be defined according to paradigm, method, samples, and key findings. Also, it will be described in a synthesized manner according to qualitative and...
Europe has a history of war and conflict that predates living memory and the idea of a united Europe is something that appears repeatedly in that history. Hitler, Napoleon, and the many Roman Emperors all sought a united Europe. Their quests although in many ways motivated by a horrifying desire for power sparked the minds of philosophers and other political thinkers to imagine Europe united in harmony and peace despite national differences. Today we have the European Union which is quite unique. After the horrors, bloodshed, and economic disaster of the twentieth century, in a desire for peace and harmony and economic and political prosperity twenty-seven states have limited their national sovereignty.2 With national interests and ambition still in mind these countries see the European Union and supranational governance and the benefits of peace and prosperity therein as something worthwhile. However, in the history of European integration there has been much conflict and Euroskepticism. Some see unity in diversity and diversity in unity as impossible, and the existence of differentiation in the EU as highly problematic. However, differentiation in the European Union’s integration process is not the hindrance it is often defined as, rather it creates further cooperation in Europe bringing the European Union closer to its objectives of peace, and economic and political growth, resulting in a more effective and efficient bureaucracy. Differentiation in the EU’s integration process has created more successful integration as it allows the nations who wish t...
The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2. 75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body.
...particularly those at high risk, to have their blood pressure checked. It is important that the community be informed about the need for screening, and understands the impact that poorly controlled blood pressure has on their health. The second element of hypertension management involves the early diagnoses of patients with hypertension by primary health-care services and the cost-effective management of the condition. It also involves educating patients about their condition and working with them in a way that will allow them to attain the highest possible level of compliance to their management. Health services should in addition to achieving good blood pressure control be screening on a regular basis for possible target-organ damage in their patients. South Africa needs to improve on both these aspects in order to promote and sustain good hypertension management.
According to Freud, personality is built from internal psychological forces. The theory provides an elaborative framework which describes human personality. Through the theory, new treatments were derived to help people in mental distress. Freud encouraged a more positive way to approach psychological distress so that even the mental illnesses themselves could be treated; many of the therapies that the theory suggested have helped to treat people with different psychological issues. Another strength of the theory is that it acknowledges the existence of a subconscious which has an impact on our behavior and not only superficial thoughts. The theory was an eye opener to health professionals of the time, by introducing insights into the human mind, and how it functions, the psychoanalysis approach became greatly important for dealing with psychological treatment (Langs 83). Many researchers claim that, even though the psychoanalysis theory has its strengths, the weaknesses outweigh them in that, from the start, this theory had no scientific evidence, only theoretical explanations. For example, the psychodynamic model explains why or what causes abnormalities in children but it lacks research evidence to back it up. Sigmund Freud based all his arguments in his own analysis. It is evident that psychoanalysis is mainly dependent on what the therapist
...re of the brain is just half of the brain so why is it the only half being explored in school? This failure to confront the other hemisphere causes weakening in the right hemisphere since the right hemisphere isn?t being exercised.
