Phineas Gage



Source 2



     Phineas Gage was a man who lived in the mid 1800's. He was a railroad worker, and his job was seal the hole with sand with a tamping iron, where the dynamite was placed. One day, while he was working on this job, somehow the dynamite caught fire and exploded while he was tamping the sand. The tamping rod went directly from his left cheekbone, threw his eye socket and out on the frontal lobe. After his injurie it was obvious that his frontal lobe was severely damaged and that his left eye did not work. It is also said that after this event, his manner changed ahd he become more rude with people. Scientists and doctors determined that every part of the brain controls a specific thing of the body, and that you can live without pieces of your brain but you would loose a funciton of your body.

      Acording to Source 1, the idea of brain localization is "This means that different parts of the brain carry out different fucntions (e.g., vision, control of voluntary movement, understanding speech, etc.) and, conversely, that not all parts of the brain do the same thing.  This may seem obvious, but other organs, such as the liver, do not exhibit localization of function; one part of the liver does the same thing as another part six inches away."
