Resumo

TLDRPhineas Gage, 'n spoorwegvoorman, het beroemd geword as 'n mediese raaisel nadat 'n ongeluk in 1848 'n metaalstaaf deur sy skedel gestoot het en sy frontale lobbe beskadig het. Hoewel hy fisies herstel het, het Gage se persoonlikheid drasties verander, wat daartoe gelei het dat hy sy werk verloor en vermy is deur vriende en familie. Hierdie geval het belangrike debatte oor breinfunksies in die middel van die 1800's beïnvloed, met sommige wat geglo het dat enige deel van die brein enige funksie kan verrig, terwyl andere geglo het dat spesifieke funksies aan gespesialiseerde areas gekoppel is. Moderne navorsing erken beide aspekte, maar onderstreep die komplekse interkonneksie van die brein se funksies, en bestudeer steeds die spesifieke gevolge van Gage se frontale lobbeskadiging.

    Phineas Gage was 'n normale spoorwegvoorman tot hy 'n ongeluk gehad het wat sy persoonlikheid verander het en die begrip van die menslike brein beïnvloed het. Tydens die ongeluk in 1848 het 'n metaalstaaf deur sy skedel gegaan, wat dele van sy frontale lobbe beskadig het. Ondanks die fisiese herstel, was sy persoonlikheid permanent verander en kon hy nie meer met sy vorige vriende oor die weg kom nie. Die geval het 'n belangrike bydrae gelewer tot die debat oor breinfunksie in die 1800's, aangesien dit die idee van gespesialiseerde funksies in die brein ondersteun het. Moderne navorsing het die rol van die frontale lobbe in gedrag en besluitneming verder verduidelik.

    1848 when Phineas Gage was clearing
  • 00:00:24
    rocks from a new railroad's future path
  • 00:00:26
    he was placing gunpowder into the cracks
  • 00:00:28
    and rocks and then detonating them to
  • 00:00:29
    clear the
  • 00:00:30
    one day he made a mistake with his
  • 00:00:32
    explosives Gage forgot to cover the
  • 00:00:34
    gunpowder he was patting down with sand
  • 00:00:36
    when he tried to Pat the gunpowder into
  • 00:00:37
    the rock it exploded and launched a 3ft
  • 00:00:40
    long metal pull through his skull the
  • 00:00:42
    projectile dragged parts of both his
  • 00:00:43
    frontal loes along with
  • 00:00:45
    it despite the gruesome injury Gage was
  • 00:00:48
    relatively unaffected by the accident
  • 00:00:50
    some Reports say that he convulsed for
  • 00:00:51
    the first minute after the impact but
  • 00:00:53
    many believe that he never actually lost
  • 00:00:55
    Consciousness regardless he was
  • 00:00:57
    undoubtedly conscious about 1 minute
  • 00:00:58
    after the impact Gage sat up and
  • 00:01:01
    actually spoke to his fellow railroad
  • 00:01:02
    workers when they wheeled him to a
  • 00:01:04
    doctor he insisted on being given his
  • 00:01:06
    time book to continue doing his job as a
  • 00:01:08
    foreman while Gage's determination to
  • 00:01:11
    continue working despite his terrible
  • 00:01:12
    injury may seem odd the effects of his
  • 00:01:14
    injury were even stranger the open Brain
  • 00:01:17
    wound healed after only 10 weeks and
  • 00:01:18
    Gage was able to count sing feed and
  • 00:01:20
    dress himself and make sense of
  • 00:01:22
    information that was given to him some
  • 00:01:24
    aspects of Gage never fully recovered
  • 00:01:26
    however his personality was completely
  • 00:01:28
    different his old friends could not
  • 00:01:30
    tolerate his newly inconsiderate
  • 00:01:31
    attitude inexplicable temper and
  • 00:01:33
    constant profanity soon he was fired
  • 00:01:36
    from his job for being nasty to
  • 00:01:37
    co-workers people who he had worked well
  • 00:01:39
    with just 10 weeks before Gage was so
  • 00:01:41
    out of control that men kept him away
  • 00:01:43
    from women and children because he was
  • 00:01:44
    considered too vulgar for them even
  • 00:01:46
    though he had physically healed
  • 00:01:47
    something was still wrong as his doctor
  • 00:01:49
    said Gage was no longer
  • 00:01:52
    Gage 11 and a half years after the
  • 00:01:55
    accident Gage died unfortunately for the
  • 00:01:57
    medical community no autopsy was
  • 00:01:59
    conducted on unique brain years later
  • 00:02:02
    his body was exhumed with permission
  • 00:02:03
    from his family and scientists studied
  • 00:02:05
    his skull they saw approximately where
  • 00:02:07
    the rod traveled through his head and
  • 00:02:08
    did their best to understand the damage
  • 00:02:10
    with their limited understanding of the
  • 00:02:13
    brain the case study became an essential
  • 00:02:15
    part of the debate regarding the
  • 00:02:16
    function of the brain in the mid 1800s
  • 00:02:19
    two prominent schools of thought existed
  • 00:02:21
    ironically both used gagee as support
  • 00:02:23
    for their Theory one group believed that
  • 00:02:25
    the brain was connected by a vital force
  • 00:02:27
    due to this vital force any part of the
  • 00:02:29
    brain could perform any of its functions
  • 00:02:32
    therefore someone like Gage could still
  • 00:02:34
    think and behave like everyone else
  • 00:02:35
    despite having lost a large piece of his
  • 00:02:37
    brain the other group of brain theorists
  • 00:02:39
    commonly referred to as the localizers
  • 00:02:41
    thought that the brain had different
  • 00:02:43
    parts that localize specific functions
  • 00:02:45
    they pointed out that Phineas Gage's
  • 00:02:47
    personality was never the same after the
  • 00:02:48
    accident the localizers believed that
  • 00:02:50
    the damage to the brain caused the
  • 00:02:52
    lasting change in Gage's
  • 00:02:55
    personality ultimately both competing
  • 00:02:57
    schools of thought were integrated into
  • 00:02:59
    contemporary brain brain Theory the
  • 00:03:00
    brain does have specific localized
  • 00:03:02
    functions modern research has shown that
  • 00:03:04
    motor functions are certainly localized
  • 00:03:06
    to specific areas localizers however
  • 00:03:09
    underestimated the interconnectedness of
  • 00:03:11
    the brain the brain has trillions of
