Journal: How our brain works?

1. When talking of the brain the word hemisphere refers to one of the two sides of this organ which is divided by the corpus callosum from the otherone.
2. The major diferences between the left and right side of the brain is that the first one is in charge of exact things as math, language, logic, and also the right side of the body, while the second one deals with the left side of the body and things as emotions, art, music, and intuition.
3.The corpus callosum is  is a group of nerve fibers that connects the left and right hemispheres of the brain, and is responsible for most of the communication between the two.
4.  Pierre Paul Broca was a French surgeon that studied the brain of a patient with a speech impairment after his death. He concluded that there is an specific part of the brain in charge of speech production, whic was called Broca's Area.
5. Roger Sperry was a northamerican neuropsychologist, and neurobiologist who won the Noble prize for his studies. He developed the idea of "split brain" which was about cutting the corpus callosum for curing epilepsy patients.This practicing brought problems because each side of the brain complement, and the result was two different brains with no communication.  After this activity the idea that the left and right side of the brain are responsible for different tasks was confirmed.
6.Carl Wernicke was a polish psychiatrist and neuropathologist who studied a patient thet had suffered a stroke and although the man was able to speak and his hearing was ok, he could not understand what was said to him. This study led to the discoverment of the Wernicke's Area which is located in the left hemisphere and works with the broca´s area. It is in charge of language comprenhension.
7. The occipital lobe is most responsible for vision.
8. The temporal lobe is most responsible for hearing and language.
9. The fronl lobe is most responsible for performing math calculations.
10. The frontal lobe is most responsible for judgment, reasoning and impulse control.
