Question 5

In 1848,a railroad foreman named Phineas Gage was injured in an explosion,when a tamping iron penetrated his skull and caused brain damage; surprisingly,he survived.The rod was 
1.25" in diameter and 3.5' long.After the accident he was able to speak,get himself up and down from a cart,and climb a flight of stairs to see the local physicians.Years later,the doctors reported that he physically recovered,but the balance between his intellectual facilities and animal propensities was destroyed.He was no longer mild-mannered,kind,and respectful; he grew obstinate,ill-tempered,and showed little self-restraint.Based on this story,what area(s)of the brain (and/or systems)do you think he injured and why?

Accepted Answer
