Phineas Gage


  • Was a railway worker that was seen as rational and calm
  • Had a metal rod go through his brain and sever his frontal lobe from the rest of his brain
  • Although he survived his entire personality changed to become violent and irrational

This showed that personality is controlled by the frontal lobe of the brain and once that is severed from the rest of the brain then it will change who you are.
