HOW DOES OUR BRAIN WORK?

The cerebral hemisphere is divided into two hemispheres, the right and the left. Each side specialized in some behavior.

The difference between the left and the right are the left controls speech, language, math, logic and all the movements on the right side of your body. The right controls the abilities, visual imagery, face recognition, music and the muscles on the left.

The corpus collasum is the communication between both the right and the left hemispheres. The thinking band are in about 200-250 million nerves fibers.

Paul Broca discovered the "Broca´s Area", is a language area also called the "speech motor area."  It has to do with the left side. He made an experiment on 2 patients to help him figure out this area of the brain. This area is located in the frontal lobe, in the middle cerebral artery and in the superior sagittal sinus vein. This area can be damage with a brain tumor.

Roger Sperry discovered the "Split Brain". "Split Brain" has to do with the corpus collasum. It the brain splits is cannot communicate and it losses the communication between the cerebral hemispire. For example if you have the "Split Brain" you will not be able to name the object that you are seen. This is because the left controls the talking and the right the visualize, then the hemisphere will not be able to communicate and you will not know what the other side of your body is doing.

Karl Wernicke discovered the "Wernicke Area". This area also has to do with language. It is located in the temporal lobe on the left side of the brain. This area is mostly related to the "Broca´s Area" both have to do alot with speech. This area can be damage by language development or usage being impaired.

The lobe that is responsible for the vision is the occipital lobe. The Temporal lobe is responsible for language. The Parietal lobe is responsible for performing math and the frontal lobe is responsible for judgment, reasoning and impulse control.
