Do Humans Use 100% of Their Brains?
Where did the persistent statement that humans use 10% of their brains originate and is it valid? It was first coined by William James, a philosopher and psychologist. Some professionals have even stated even lower percentages, like Margaret Mead saying that we use 6% of our brains (3). If this statement is true, it implies that humans could behave very differently and perhaps with greater thought and purpose. If the statement is a fallacy, it supports the brain equals behavior theory, such that the brain is not harboring unused capacities and behaviors.
The 1012 neurons in the brain have not all been researched for activity or not, but researchers have found no evidence for unused abilities or large, unused regions of the brain. Researchers know that humans do not use every region of their brain for every behavior, unless we are doing something so complex that it requires all of the brains capacities. At any given point in time, about 5% of the neurons are active, but over time and change of ones behavior, PET scans and fRMIs show that the vast majority of the brain is active (2). Perhaps this is an evolutionary adaptation: to conserve energy and prevent an electrical and chemical overload from all the neurons firing and inhibiting. The brain is about 3 pounds, using an inproportionate 20% of the bodys oxygen- rich blood, but is only 2% of the bodys total weight (3). The significance of the brain receiving so much of the bodys energy supply, reveals its ability to perform important functions. The heart and the lungs main function is to provide the brain with oxygenated blood, presumably because the brains will be performing essential neuronal activity relevant to the days behavior.
The highly specialized regions of the brain give some insight into the many functions that the brain is capable of doing. So the development of the brain into specific sections that have been researched to facilitate specific functions, provides evidence that these regions are active in a normal humans lifetime. The fact that the brain has a highly ordered procedure for developing, leads researchers to believe that each region of the brain is essential. In fact, researchers have found several regions to account for one function, to imply that the collaboration of several brain regions is sometimes necessary for normal functioning.
Other evidence against the statement that humans only use 10% of their brains.
This paper will focus on the future of the U.S. Automobile industry as the United States recovers from the worst recession we have experienced in the past 75 years. I will provide information on the following topics pertaining to the U.S. automobile industry:
Ravitch, Diane. "The Success of Charter Schools is a Myth." 2012. Opposing Viewpoints. Document. 20 November 2013. .
To understand the actual differences of charter and public school quality of education, it is important to emphasize a fact often lost in the debate; namely, charter schools are public schools, which simply operate under different guidelines. This reality is more critical because of how perception clouds it. Charter schools are perceived as private institutions, supporters of them tend to be conservatives who feel the schools represent the value of competition in education, while opponents typically express the need for public school reform as more crucial in promoting educational equality (Rofes, 159). This political and ideological compone...

brain is a very complex part of the body that has everything to do with daily life and the ability to learn. As many people do not understand there are two parts of the brain and each works completely different in how one will learn and retain information. Why is the brain such a complex system and has the ability to adapt to every situation. We are going to be looking at the Left and Right side of the Brain and how each hemisphere works from the time you are a child and starting to receive information and the brain as a whole. We will also be looking into the Right side of the brain and how it learns faster as the Left side retains information. There has been a lot of research and case studies on the brain and how different people from different back grounds learn based on ethnic groups such as the American Indians and how they learn different with their brain.
The automobile sector has been a robust sector that has experienced tremendous growth in the past seven to eight years. Apart from two years in particular -2008-09 & 2012-13, there is general trend of ten percent plus growth in various segments like passenger car, commercial vehicles, two and three wheelers. The following chart shows the growth rate of various years in each sectors.
Charter schools, which exist all over the United States, are “rooted in the premise of public, free education nestled in the ideas of parental choice” (Pardo 6). Since “Minnesota launched its first charter school in 1991”, charter schools have experienced “an enormous increase in number to over 5,300 by 2011” (Chen). Like traditional public schools, charter schools are “funded with public money” (Chen). However, parents have to “submit a separate application to enroll their children in charter schools, and spaces are often limited” (Pascual). Each charter school has an independent governing board that oversees finance (Pardo 6). Enrollment is based on choice, with parents selecting schools due to their specific focus, curriculum or other features (Pardo 7). When enrollment is exc...
The brain has many different parts to it which help one function through daily life; parts such as the cerebrum which controls voluntary movement and regulates functions such as thinking, speaking and the ability to recall information. The cerebellum controls the balance and coordination and finally the brain stem, which consists of the medulla oblongata and the spinal cord which controls all involuntary functions such as breathing, heart rate and blood pressure. The brain stem is also able to carry out these actions even when someone is asleep. To fully understand how crucial the brain is to survival one must understand the functions of the brain stem.
The brain has four major lobes. The frontal lobe, the parietal lobe, the occipital lobe, and temporal lobe are responsible for all of the activities of the body, from seeing, hearing, tasting, to touching, moving, and even memory. After many years of debating, scientist presents what they called the localization issue, Garret explains how Fritsch and Hitzig studied dog with conforming observations, but the cases of Phineas Gage’s accident in 1848 and Paul Broca’s autopsy of a man brain in 1861 really grabbed the attention of an enthusiastic scientific community (Garret 2015 p.6)
The brain is the most important organ in the body with our heart. It controls every action, thoughts and regulates our bodily function. It is divided into section, each of them are responsible for various process. Before we can understand dopamine, we must talk about the different parts of the brain. The frontal lobe is the main difference between us and animals. ...
As the rate of charter school failures continues to increase throughout the years, it has become that much more difficult for the charter school system to be taken seriously by the public. Rather than being perceived as a new found educational establishment, some are going as far as referring to the charter school sys...
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.
Many people will always say that, they are more of the left-brain-thinker or right brain thinker. Over the past years, different researchers on the functions of the brains have done extensive research. Most studies suggest that our brain works in two different ways (Brynie, 2009), however, some of the studies reveal that, the left side and right side of the brain works hand in hand with each other, and there is no way one side can function without the other. Human beings are labeled as right brain thinkers, and left-brain thinkers.
The Internet has created a generation of the most efficient multi-taskers ever born. Many people will have at least four tabs open as a time (Google, Facebook, Youtube, Pandora, Wikipedia, Gmail, etc.). People are constantly jumping from one web page to the next, clicking on links and opening new tabs and browsers. The method through which knowledge is gained has transitioned from deep reading to fast skimming. Every time a web page is opened the viewer is bombarded with information, almost every page has advertisements or links to additional information lining its sides. The Internet has made mountains of information available to almost anyone. It is fast and easy to find information and facts. Essentially the Internet has become the fast food of knowledge. It is convenient but it skips the element of effort.
The development of the American Auto Industry took place over many, many years, starting with Mr. Henry Ford building the first car in 1896. The industry has evolved, to what it is today and represents approximately 10% of the country’s Gross Domestic Product (GDP). According to the Bureau of Labour and Statistics, ‘the automotive industry includes industries associated with the production, wholesaling, retailing & maintenance of motor vehicles’. These industries are industries that have a tremendous impact on the U.S economy and can be directly impacted by changes in U.S. production and sales of motor vehicles.
