Important Note: Phineas Gage is an interesting way to learn about the relationship between the frontal lobe and our behaviour. However, there are many other studies that we use in this course to demonstrate important concepts like localization of brain function. Therefore, Gage should not be used in exam answers.
Phineas Gage was a railroad worker who was putting dynamite into rocks while working with a team to lay tracks. As he used a six-foot bar to pound the dynamite powder into the rocks it ignited, essentially making the long steel pole a bullet that fired up through his left eye, through his skull and landed about 50ft away, covered with bits of brain and blood. Gage survived and was even conscious while he rode on the ox cart to the nearest town to get help.
As a result of the incident, Gage’s behaviour seemed to change as he went from being a rather mild-mannered man to “no longer Gage” as his friends said. Reports have even said that he was no longer allowed to be around women because he would often say rude things to them. This was in 1848 and Harlow, the Doctor who treated Gage, made a few observations about the change in Gage’s behaviour that has made him one of the first and most famous cases that links brain damage to personality change.
