Phineas Gage was an American railroad foreman who survived a severe traumatic brain injury in 1848 when an iron tamping rod passed through his skull. His case became one of the most famous in neurology and psychology because it was associated with later observations about changes in behaviour and personality after frontal-lobe damage.

Biography

Gage was born in July 1823 in New Hampshire, United States, and worked as a railroad foreman. He became widely known after a severe industrial accident in Vermont in 1848. He died in California in May 1860.

1848 accident

On 13 September 1848, while preparing a blast in Cavendish, Vermont, an iron tamping rod was propelled through Gage's head. He survived the accident, making the case unusually well documented for the period.

Scientific significance

Gage's injury has been used in discussions of localisation of function in the brain, especially the role of the frontal lobes in decision-making, emotion, and social behaviour. The injury is commonly described as damaging the frontal lobe, particularly the prefrontal region, and his case became important in studies of brain function, personality, and behaviour.

Later interpretation

Accounts of Gage's later personality have varied over time. Modern historians and neuroscientists have debated how much his behaviour actually changed after the accident, with later scholarship questioning the extent of the reported personality changes.
