Left-Right Brains

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

helped

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
