On September 13, 1848, a groundbreaking discovery was made by Phineas Gage, a 25-year-old railroad construction foreman. While working on a railroad site in Cavendish, Vermont, an accidental explosion sent a 3-foot-7-inch (1.1 m) long, 1.25-inch (3.2 cm) diameter iron rod through Gage's left cheek, behind his left eye, and out through the top of his head. Miraculously, Gage survived the incident, but his personality and behavior were drastically altered.
Before the accident, Gage was known as a responsible, efficient, and capable foreman. However, after the incident, he became impulsive, fitful, and prone to profanity. His friends noted that he was "no longer Gage." This dramatic change in his personality provided early evidence of the brain's role in determining personality and behavior, particularly the functions of the frontal lobe.
Gage's case was studied extensively by doctors and scientists of the time, and his skull and the tamping iron were preserved and are now on display at the Warren Anatomical Museum at Harvard University's School of Medicine. His case has been cited in numerous books and scientific papers, and he has become one of the most famous patients in the history of neuroscience.
The story of Phineas Gage has fascinated scientists and the public alike for over 170 years, as it provided early insights into the localization of brain functions and the role of the frontal lobes in personality and behavior. His case has become a classic example in psychology and neuroscience textbooks, illustrating the delicate balance between the brain's structure and function and how damage to specific areas can lead to profound changes in an individual's mental processes and behavior.
