Irrespective of the hyperbole concerning his changes in behaviour , the important legacy of this unhappy case (Gage died 12 years after the accident following a severe convulsion) is arguably the birth of neuropsychology. This is the idea that specific parts of the brain perform specific tasks (modularity): if, following damage to a part of the brain an individual can no longer perform a specific task, we deduce that this damaged part of the brain is responsible for that task.
Happily, students of Psychology now have the opportunity to celebrate Gage’s contribution to the discipline through a range of Phineas Gage-related merchandise. Perhaps you would like to relax around your house in a Gage-shirt, be the talk of the lecture theatre in your Gage-jumper, drink gin from your Gage-mug, and most appropriately dress your canine in a Phineas Gage dog suit. For the more creative, you could always produce your own Phineas Gage costume – suitable for parties, weddings, and other family events.
