On September 13 , 1848 , an accidental burst repel a meter - long iron rod through the skull of Vermont railway worker Phineas Gage . fabulously , Gage make it , but the mill about side - effects allow science its first clue about how the brainpower dissemble our personality .
The pole was drive straight up through the skull , passing just under the leftover centre and into his encephalon . The rod kept right on go , landing about a hundred feet from the injured Gage . outstandingly , Gage was bring back to health by local physician John Harlow , and he even lived for another twelve long time . But Gage was never quite the same , becoming unreliable , profane , and leave to out or keeping remark , as though he had lose all his inhibitions .
Cardiff University neuroscientist John Aggleton explain :
“ It ’s reported that he became what now would be classically describe as ‘ disinhibited ’ – this is a classical term for what happen to some people after damage to their head-on lobe . So , he misplace his inhibitions , both in a social and emotional context . He would be rather high . Difficult companionship , to put it gently . ”
To be average , if I had a cadence - foresighted iron rod driven through my skull , I feel like I might just stop deal about punctuality or societal niceties , even if my brain was completely undamaged . Of course , that was just a little fraction of Gage ’s personality change , asDr . Harlow reported :
Gage was spasmodic , irreverent , indulging at times in the grossest profanity ( which was not previously his usance ) , manifesting but small compliancy for his comrade , impatient of restraint or advice when it conflicts with his desires , at times pertinaciously obstinate , yet impulsive and vacillating , devising many plans of future mathematical process , which are no sooner arranged than they are abandon in turn for others seem more feasible . A child in his intellectual electrical capacity and manifestations , he has the brute passions of a strong piece . former to his accidental injury , although untrained in the schools , he possessed a well - balanced mind , and was search upon by those who cognise him as a shrewd , fresh businessman , very energetic and persistent in accomplish all his plans of operation . In this respect his mind was radically changed , so decidedly that his friend and acquaintances enunciate he was ‘ no longer Gage . ’
It was n’t just his personality that was pretend . He only remembered about half the protagonist he had had before the accident , and he lose any concept of money . Dr. Harlow once offered Gage $ 1,000 for a few pebble he had on him , but Gage resist , as though he had no way of guess the economic value of the money proportional to his pebbles .
Gage ’s combat injury reveal something fundamental about the head , as Melbourne University psychologist and Gage expert Malcolm Macmillan explain :
“ When Phineas ’ accident occurred , there was no accepted doctrine of the psyche having functions . The only point of survey that was react to that was that of the phrenologist , the people who thought that bumps on the outside of the skull indicate the organs within the brain – therefore the parts of the brain that had special functions . ”
Experts had various different takes on Gage ’s wound . Some argued his personality modification discover certain parts of the psyche were responsible for for specific functions , and their destruction had rob Gage of a part of his personality . Others argued the fact that Gage still officiate at all was substantiation that the genius could rearrange its structure and allot unlike parts of the brain to take over the tasks of the destroyed areas . The truth lies somewhere in the middle .
sess lived for another twelve years after his accident , but his story does n’t have a happy ending . In 1859 , he moved to San Francisco to inhabit with his sept , as his increasingly poor health and epileptic fits made him unable to bear out himself . He die in 1860 , and MacMillan suspects the branding iron retinal rod ultimately complete off the line it began back in 1848 :
“ Some of the belated - term effect of that sorting of traumatic brainiac accidental injury is the formation of scar tissue . Scar tissue often becomes the decimal point from which epilepsy develop . ”
He is said to have been bury with the iron pole , but his rest did n’t last long . In 1867 , Dr. Harlow secured permission to disinter the body , and Gage ’s skull now sit on display next to the perch at the Harvard Medical School .
