Phineas Gage was an american railroad construction foreman who is known for surviving an accident in which a big iron rod was driven completely through his head destroying his frontal lobe. This happenned on September 14, 1848, Gage was preparing the roadbed for the Rutland and Burtlington Railroad in Vermont. He had to add blasting powder, a fuse, and sand and them compact the charge into the hole using a large iron rod. The sand was added at 4:30 p.m and the powder exploded carrying an instrument he was using through his head, this tool was an inch and a fourth (diameter) and three feet of length it entered on the side of his face and later passing back on the left side and out of the top of his head. This caused him to change his personality and become a mean person, he literally lost all of his friends and lived alone for the rest of his life. This accident helped investigations and because of this people know that the personality has to do with your front part of the brain which is the part that got damaged. That is a very interesting fact that I learned. Brain localization means that different parts of the brain have different roles and functions in our brain. That may seen obvious but for example 2 parts of our liver do the same function so not every part f our body had different roles. The brain also exhibits lateralization which means that the cerebrum has 2 different parts the left and the right which are different in some ways and alike in others. Some people are more left brain and others more right brain; both like different things. The left side controls the right side of the body and the right side controls the left side of the body. It is amazing how Gage could survive that accident but unfortunately he lost his entire life because of it.
