The left and right hemispheres of the brain have many different functions, but they also work together to accomplish certain tasks. The brain is a soft, shiny, grayish white, mushroom shaped structure. It is a bundle of nerve tissue that has a mass of about 3 pounds on average. During the 1900s a neurophysiologist known by the name of Roger Sperry had determined that the 2 hemispheres operated separately but could still communicate with each other. In the 1950s the corpus colossus was discovered.
It sits and is connected to both hemispheres and helps them communicate. On the other hand, over the past 2 decades the brains and nervous systems of various animals have had a tremendous impact on our findings on the 2 hemispheres. It has mainly

1. This test would indicate which side of the brain was working after a piece of the brain was taken out.
C. A simple way to study the left and right hemispheres of the brain is to discontinue brain function to one side of the brain.
1. This can be done by covering one eye or ear and asking then to do specific activities. D. There has been tests performed on animals such as cats.
1. A part of the cats’ brain tissue was removed.
2. They then attempted to teach the cat a series of tricks.
3. The goal from this test was to see what aspects were missing from the cats process to learn the tricks.
IV. Although there can always be issues there are many solutions to those issues as well.
A. A surgery was performed that had to do with seizures.
1. This seizure surgery was successful with removing part of the brain.
2. It did not affect their intelligence, personality, or mental capacity.
B. Some key issues with the brain are learning disabilities and psychiatric illness.
1. The doctors decided that these issues occur when connection between the 2 hemispheres was lost.
2. It also causes seizures which usually occur in one side of the

It controls the way we see shapes, colors, and also how we hear music.
1. It also controls our sense of direction and getting to our final destinations.
C. It is known to hold the center of all of our emotions and feelings.
D. It is also responsible for artistic abilities and our imagination.
VIII. The bilateral nature of human beings means many of out body parts have 2 symmetrical identical parts such as lungs, kidneys, legs, hands, and the brain are both identical on both sides of the body. Science based out look on brain symmetry left and right is a good beginning to research on brain behavior relationships. This topic has been recently updated in the profession of neuroscience. There are parts of the brain such as the cerebral cortex, frontal lobe, optic nerve, and the parental lobe are just a few examples and they all are on both the left and right side of the brain. Earlier in the 1860s a French physician by the name of Paul Boca showed that some patient with speech problems noticed that the left side oh the brain was damaged. Typically, when one side of the brain isn’t doing its job that would be a problem because the brain controls everything we do and everything has to run correctly for anything
For example, when researchers were working with the mental mirror box, a box that tricks the brain of a patient with a nonexistent limb that the limb is actually there by reflecting the healthy limb, they found that the individual feels as if the limb is present and healthy. Researchers also found that if an individual scratches a particular spot on his or her face, that fulfills the itching sensation that was previously felt on the nonexistent arm. This is because when one area of the brain is not being used, such as the arm map when the arm is amputated, another part of the brain map takes over, such as the face. This is an extremely interesting finding which explains why blind or deaf individuals experience such profound functioning in their other
It sends information for sleep, hearing, taste, and even eye movement. Corpus Callosum: The corpus callosum connects both hemispheres of the brain and allows them to relay messages between one another. People who have a severed corpus callosum can essentially function as 2 different people at the same time, with the left half of their body performing one task, and the right half another. Frontal Lobe: As the largest lobe in our brain, this lobe play a significant role in personality and impulse control.
The video Severed Corpus Callosum by the Scientific American Frontiers describes the case of a split-brain patient Joe. The recording starts on the campus of Dartmouth College in New Hampshire where Dr. Mike Gazzaniga, one of the leading scientists of this place has been working with Joe, a man with two brains for over a decade. Doctors have to perform brain surgery to correct his epileptic problem and to stop the daily seizures that were affecting his life. The procedure severed the connection between the two halves of his brain cutting the corpus callosum to prevent the spread of the electric storms that causes seizures. Yet, it also stopped the communication between the left and right halves of his brain.
Corpus Callosum- I am able to understand the words of the metaphor that my grandpa says in my left hemisphere. Through my right hemisphere, I am able to interpret the metaphor. Frontal Lobes-
Firstly, the human brain is a complex organ that commands a variety of different functions within the human body. One specific function of the human
The right side of the brain shows emotion and living in the present. As a man who follows a murderer to his house
In the sixth grade, I took a test to see if I was left- or right-brained. To my elementary eyes, the result of that quiz would be the truth from on high—a resolute word that would define the man to come as either analytic or artistic. Unfortunately, the oracle I sought gave me a perplexing answer. Much to my disbelief, my tallied score yielded a perfect split down the middle. Was I mentally ambidextrous or mentally challenged?
In this process a patient will have a seizure, an uncontrolled electrical disturbance to the brain. It can cause changes in your behavior, mood, movement, or even unconsciousness. But it is different for each person who is diagnosed with a different form of epilepsy. Some may be drastic while others are minor, but both affect an individual 's mental health grealty. Making them question life, with all the medicals fees, medications, and fear of overall losing their life.
One characteristic that many people believe it distinguishes Homo sapiens from other apes like chimpanzees or bonobos is our capacity for intelligence. Another distinguishing trait is the human capacity for a full time bipedalism. So It is no accident that many anthropologists have recognized a correlation between human bipedalism and intelligence. Carl Ernst von bear once remarked “Upright posture is only the consequence of higher development of the brain”. It is hypothesized that bipedalism allowed hominins to use their hands for stone tools and more efficient forging, considering that the brain is the most metabolically taxing organ in the body, in humans at least, it takes about twenty percent of our energy consumption.
It turns out that even when axons get shuffled, the brain managed to normalize the signals and shift its map to un-shuffle the signals. This breakthrough was so important because it concluded that the brain was indeed plastic. Merzenich scoured through past experiments for any type of evidence that could also corroborate that the brain was plastic. He came across an experiment conducted by Karl Lashley. In the experiment Lashley stimulated a particular spot in a monkey’s motor cortex and observed what body part was caused to move.
1. Introduction Absence Seizures have been a medical concern for a long time, and were first described in medical literature back in 1705 by Poupart (Temkin, 1971). According to The World Health Organization (WHO) at least 40 forms of epilepsy have been identified, and they are characterized by an abrupt and transitory synchronization of neuron activities, whose causes are not always well known. 2.
Parts of the brain and their functions: the frontal brain with controls the higher mental processes. The midbrain, which controls emotions, motivations and the limbic system. The hindbrain which controls movement, and lower mental functions. 3. Split brain: when the corpus callosum is split it destroys the connection between the left and right side of the brain.
Side inattention is not to be confused with visual field deficits. Hemi-inattention or neglect has lost the attentional Central Nervous System (CNS) mechanisms that drive the search for visual information. The inattentive client makes no attempt to search for information on the side of the body affected, as if that side no longer existed (Early, 2013). Client assessed in this case study is a 40 year old, female. She is married, husband works full-time.
There two region of brain’s left hemisphere helps to communicate such as, Broca’s area and Wernicke’s area (there are several others). Broca’s area is activated in hearing and signing. Wernicke’s area (there are several others).
They can be a response to physiologic event, such as fever, toxins, or hypoxia, or a reaction to some type of psychic stressor (psychogenic seizures) (Dimaro et al., 2014 and Hockenberry & Wilson, 2015). An epileptic seizure is a sudden and transient occurrence of signs and/or symptoms that are the result of an abnormal activity of the brain. Epileptic seizures are the common and defining component of the disorder that is referred to as epilepsy. In other words, epilepsy is the tendency to have repeated (two or more) spontaneous epileptic seizures (Roswall, 2010; Mustapha et al., 2013 and Fisher et al.,
