Meet the man who was shot in the head with an iron rod – and SURVIVED: Scientists reconstruct the face of Phineas Gage as it was moments after freak accident 175 years ago
A horrific accident that revolutionized our understanding of the brain has been brought to life by science using the skull of the man who survived.
Phineas Gage was paving the way for a new railroad in Vermont on September 13, 1848, when an accidental explosion turned his life upside down.
An iron rod was shot into his head, through his skull and out the other side, before he landed some 25 meters away 'smeared with blood and brains'.
Much of Gage's left frontal lobe was destroyed, but he lived another twelve years and his case became part of medical folklore.
Now we can see his face at the moment of impact, after his skull was used to complete a forensic reconstruction of his facial features.

Forensic facial reconstructions usually show what a person looked like when they died, but in this case it captures a single moment from a person's life.
Cicero Moraes, author of the new study, said: 'In Gage's case, the facial expression is not the most important part of the trial, as we have at least two photos of him.
'The interesting thing about this project was the use of 3D technology and the knowledge gained from surgical planning to reconstruct the dynamics of the rod passing through the head.
“I want to understand what happened at that moment.”
Scientists can recreate a person's face from the skull by determining the likely depth of skin on different parts of the head, using data donated by living people.
Mr. Moraes also uses anatomical deformation, which virtually deforms a donor's face until it is compatible with the skull in question.
He has previously recreated historical faces with traumatic injuries, recreating the likeness of a man taking an ax to his mouth during the Battle of Visby in 1361.
But Mr. Gage's case required some extra work.
Cicero said: 'I virtually segmented the skull where it fractured at the time of the accident
'I simulated the passage of the beam where the injuries indicated, adjusted the pieces of the skull and thus obtained the basic dynamics of the accident.
“A high-resolution CT scan of a brain was imported into the scene and that brain was adjusted to best fit Gage's skull space.

While he was pounding gunpowder, a metarod was shot through his head with such force that he was thrown back several meters
'I also imported a set of cerebral veins, well adapted to space.'
He continued: 'With all this together it was possible to animate the scene, seeing where the beam passed and which part of the brain it hit.
'It was also possible to create visual teaching material so that interested parties could better understand the severity of the accident.'
At the time of the accident, the obstacles were removed by drilling a hole in them, filling it with blasting powder and then tamping it down with an iron bar.
Gage was ordered to tamp it down, but his rod sparked against the rock, igniting the powder and causing a premature explosion.
His changed personality after the accident fueled the medical debate.
Some said it confirmed the idea that different parts of the brain performed different functions, while others said it showed how one part of the brain could take over for another if it were lost.
John Aggleton, professor of neuroscience at Cardiff University, told the BBC in 2011 that both were right to some extent.
“It alerted people to the fact that a part of the brain – the frontal lobes – that we associate with some kind of planning and intellectual strategies also played an important role in emotions,” he said.
After his accident, Phineas Gage made several public appearances before taking a job as a long-distance stagecoach driver in Chile

For Mr. Moraes, a Brazilian graphics expert, working on Gage's case was personal.
As a child, he watched his father commit suicide with a gun, and in 2011, Cicero's head was grazed by a bullet during an armed robbery, during which he also suffered a broken rib.
He said: 'When I was working on Gage I saw the history of someone who had been in a very serious accident but he didn't let it affect him.
“He is an example of how life can be cruel to us, but how we can fight and win even with very low probability. This case made me think about how much I have overcome in my past.
“In other words, this Phineas Gage project is a milestone for me because it represents overcoming.”
After his accident, Phineas Gage made several public appearances before taking a job as a long-distance stagecoach driver in Chile.
As his health deteriorated, he later moved to California, where he would die in San Francisco in 1860 at the age of 36.
Malcolm Macmillan, professor of psychology at the University of Melbourne, told the BBC that the epilepsy that killed Gage was likely a result of his injury.
Mr Moraes published his research in the journal OrtogOnLine.
