Cerebral Hemispheres By Troy Armentrout

The Cerebral Hemispheres : 

The Cerebral Hemispheres The brain is a very complex and vital organ to the human body. It is split up into two hemispheres, the left and the right. Each side has its own separate functions.

The Right Brain : 

The Right Brain Since there are two hemispheres, they control different functions. The right hemisphere of the brain is credited with the movement of the left side of the body. The right brain is the imaginative side of the brain.

The Right Brain (cont.) : 

The Right Brain (cont.) The right brain is holistic, meaning that it can take multiple parts of something and see it as a whole, something like a puzzle. So basically the right brain recognizes one thing and can visualize what it belongs to.

The Right Brain (cont.) : 

The Right Brain (cont.) The right brain is great in the comprehension of emotion. In an experiment, subjects were shown facial expressions and the subjects were able to decipher the emotions.

The Left Brain : 

The Left Brain The left brain specializes in the control of logic, thought process, and reasoning. It is more analytical by figuring out things step-by-step. As opposed to the right brain, the left brain is linear, meaning that the left brain puts things into a certain order.

Functions : 

Functions The Left Brain The Right Brain Logical Analytical Linear Verbal Symbolic Intuitive Synthetic Holistic Nonverbal Concrete

Damage to the Right Brain : 

Damage to the Right Brain There are two areas a stroke can occur, one of them being the right brain. People who suffer damage in the right brain due to a stroke often have a hard time completing simple tasks that they think they can complete such as eating or walking.

Damage to the Left Brain : 

Damage to the Left Brain The other area that can be damaged by a stroke is the left brain. If someone suffers a stroke in the left brain they have difficulty analyzing and understanding perceptions. They also lose the ability to solve any difficult problems.

Born Deficiencies : 

Born Deficiencies What about the people who are born with a deficiency or problems with either side of their brain? The left brain in patients with Down syndrome is quite different from the normal pattern seen in healthy humans. This side shows lateralization for the production of simple and complex movements, and the right side shows lateralization for receptive language.

Conclusion : 

Conclusion As one can see, the brain is a very complex organ. Although it controls simple tasks, the depth of these tasks is almost too advanced to study. Numerous experiments and studies have made it easier on people to understand the functions of the two hemispheres, but will we ever understand the brain completely?

Questions : 

Questions True or False: The right brain is the analytical side of the brain. True or False: The left brain is more logical than the right side. True or False: The brain is 100% understood by the scientists who study it.
