The tragic accident of Phineas Gage in Vermont 1848 is probably the most well known case study in Psychology. An explosion propelled a metal rod into his left cheek area through the top of his skull, destroying much of his left frontal lobe. The accident was not immediately fatal and he was able to resume life for 11 years, however his personality was permanently altered. Although not immediately, this case provided great insight into the functioning of the brain and its role in personality.
