How Brain Works

1. Hemisphere regarding the brain is the 2 sides in which the brain is divided in left and right. Usually the right side of the brain controls the left side of the body and the left side of the brain controls the right part of the human body.
2. The right and left side of the brain are both responsible of controlling certain functions on the human body. The major differences are that the right side controls more the understanding of things and remembering them and also your body position and the position of things. The left side by the other hand controls the understanding and use of language like listening, reading, speaking and writing. 
3.   .  The corpus callosum is a huge bundle of nerve fibers found in mammalian brains. It is the connection between the hemispheres the right and the left sides of the brain.
4.     .      Broca’s area was discovered by Pierre Paul Broca and was named after him in 1861. Broca discovered the area after studying the brain of a patient with speech impairment after his death. The study included a patient Broca had called Tan who died and was speechless. Broca perfomed a detailed post-moterm examination on his brain.
5.             Split-brain evidence came to be during the 1960s by Roger Sperry and his colleagues. In the 19^th century researches made on certain peoples brain injuries made it possible to suspect that the “language center” in the brain was located on the left hemisphere. People with lesions in two specific areas on the left side lost their ability to talk.
6.       .     Karl Wernicke a German neuroanatomist, pathologist, and psychiatrist made fundamental discoveries about the brain and its functions. The Wernicke’s area involved understanding of language, in the posterior portion of the left temporal lobe. Wernicke’s area is associated with the processing of words that we hear being spoken, or language inputs.
7.          The Occipital Lobe
8.     .    The Temporal Lobe
    9. Parietal Lobe 
    10. .Frontal Lobe
