What Really Happened to Phineas Gage?
Summary
TLDRPhineas Gage's remarkable survival after a tamping iron pierced his brain in 1848 intrigued psychologists and contributed to brain specialization theories. Contrary to myths, Gage's personality changed post-accident, but he was not entirely unemployable or a social outcast. He worked as a carriage driver in Chile, suggesting his cognitive abilities were somewhat intact. Modern research using a 3D model of his skull indicates damage to his left frontal lobe, affecting decision-making and emotional processing, and a significant loss of white matter. This case underscores the brain's resilience and the importance of accurate storytelling in neuroscience.

🧠 The Phineas Gage Story: Debunking Myths
Phineas Gage is a pivotal figure in the history of psychology, known for surviving a severe brain injury caused by an iron rod passing through his skull in 1848. Contrary to popular myths, Gage did not become a monster or a circus attraction. While his injury did alter his personality, leading to social impairments, he was not rendered unemployable or incapable of functioning in society. Gage eventually worked as a carriage driver in Chile, indicating a significant recovery. The myths surrounding his story likely arose from a mix of honest mistakes and the use of his case in debates over brain specialization. The actual records, primarily from Dr. John Harlow who treated Gage, suggest a more nuanced recovery process and a life that continued with purpose and employment.
🧬 Understanding Gage's Brain Injury and Its Impact
Modern research, including a 2012 study that created a 3D model of Gage's skull, has shed light on the specifics of his brain injury. The damage was主要集中在他的左前额叶,这是与决策制定和情绪处理相关的大脑区域。The study suggested that Gage lost a significant portion of his white matter, which connects different parts of the brain, but only a small percentage of his gray matter. This distinction is crucial because white matter can regenerate, which could explain Gage's ability to recover and continue working. His case is now seen as analogous to modern degenerative diseases like frontotemporal dementia, which affect similar brain regions and can cause personality changes. The accurate recounting of Gage's story is important not only for historical accuracy but also to avoid dehumanizing those who experience brain injuries today, emphasizing the resilience of the human brain.

most of the time when a large object
passes through your skull you will
receive what is called a lethal injury
but for one person named phineas gage
that famously did not happen and you
don't survive an iron rod through your
brain without psychologists paying
attention so his name can be found in
basically every intro to psych class but
if your story travels far and wide
chances are it doesn't get told right
every time so it's no surprise that the
tale of phineas gage has become quite
colorful and
inaccurate in most cases but what's true
is that he survived a seemingly
unsurvivable injury and his stunning
recovery helped settle some debates
about how the brain works the first part
of the story is usually told correctly
in 1848 gage was 25 and a foreman
helping lay railroad tracks in vermont
he was using an iron rod three and a
half feet long and over an inch wide to
pack sand onto an explosive when it went
off firing the rod at his head the rod
entered his skull below his left eye and
then came out through the top of his
head landing about 30 yards behind him
he miraculously survived but the doctor
who first treated him reported that his
friends said he was quote no longer gage
the injury had changed his personality
and that's about where the story starts
to spiral out of control in some stories
gage is described as becoming a monster
of a man a mean psychopath that could
never function again in society some
textbooks say that he never worked again
that he became a vagrant or a circus
attraction or in one example that he
survived for 20 years with the rod still
in his skull but pretty much none of
that's true we only have a few primary
sources for gage's life and most are
from the doctor who first treated him an
american physician named john harlow but
those records suggest that in some ways
gage recovered pretty quickly within
four weeks of the accident harlow
recorded that gage's memory was as
perfect as ever for example a visiting
doctor wrote that a stranger would
notice nothing peculiar about him and
six months later harlow wrote that gage
was fully recovered though that might
have been a little optimistic he later
described gage as being intellectually
impaired nothing extreme just a little
slower at things like gage had
previously been thought of as one of the
best at his job and a shrewd smart
businessman but some of his post-injury
records suggest he became
kind of average and it is true that he
didn't get his old job back though that
probably wasn't due to a cognitive
impairment but rather because he became
harder to work with reports suggest that
after the accident he lacked respect and
kindness was more profane and gotten
more conflicts in other words he
suffered a social impairment at least at
first but he didn't become like a wholly
horrible person like some accounts
suggest and he did in fact hold down a
steady job later on gage moved to chile
and worked as a carriage driver for
years though not considered as high
status as his old job as a foreman it
still required him to exercise social
skills as well as cognitive and motor
skills and a doctor who knew him there
described him as having quote no
impairment whatever so clearly he wasn't
permanently unemployable or unable to
function in society it's likely that
such larger than life stories of gage
arose in part through honest mistakes
like the idea that he was a circus
attraction may have arose because he
likely made some paid appearances at
barnum's museum in new york which though
named for that same pt barnum of barnum
bailey was not part of any circus and it
seems like some psychologists writing
about him later on got his case mixed up
with later cases of brain damage also
before pdfs and the internet it was
likely pretty hard for textbook writers
to get their hands on the actual case
notes to fact check what they'd heard
but another big reason that myths grew
about gage is the same reason he's a
pretty important figure in the history
of psychology almost immediately he
became like a pawn in fights over how
the brain works today we take for
granted the idea that parts of the brain
are specialized for certain purposes but
at the time no one was certain of that
and others had a more holistic view
basically that all of it was equally
important for pretty much everything in
fact at the time the biggest proponents
of specialization were phrenologists
adherents of the racist pseudoscience
which proposed that personality and
intelligence were related to bumps in
the skull so some psychologists may have
emphasized gage's recovery specifically
to attack phrenology and being able to
recover did seem to argue against
specialization after all if the brain
was specialized you couldn't lose a lot
of brain tissue and still be mostly fine
meanwhile according to the phrenologists
who again were wrong the rod hit him in
the parts of the brain responsible for
benevolence and veneration so they
likely overemphasized the changes in his
social abilities leading to the bizarre
stories that then snowballed today
gage's true story fits with our
understanding of brain specialization
just not the way that phrenologists
thought what exactly happened to his
brain wouldn't be studied in depth until
over a century and a half after his
accident gage died 11 years after the
incident and was buried but his skull
was later exhumed and in a study
published in 2012 and plos one
researchers were able to create a 3d
model of that skull to fully examine
what happened to it based on the
placement of the fractures and what's
known from modern imaging of brain
anatomy the researchers suggested that
the damage was largely to his left
frontal lobe a part of the brain which
is associated with decision-making and
emotional processing that might explain
some of the more subtle deficits he
suffered they also found that it was
likely most of the damage occurred to
white brain matter instead of gray
matter brain tissue that appears white
is made of the myelinated axons that
connect neurons while gray matter is
made mostly of neuron cell bodies the
research proposed that gage lost around
11 of his white matter specifically
white matter connecting the orbital
frontal cortex of the frontal lobe to
the limbic system while perhaps only
losing four percent of his gray matter
and that could help explain his recovery
because while gray matter doesn't grow
back well after injury it is possible
for white matter to regenerate this also
makes gage's case look a lot like modern
degenerative diseases like
frontotemporal dementia similar brain
regions are affected by the disease and
some of the symptoms associated with
personality change can also occur and
that modern comparison is a good
reminder of why it's important to debunk
the myths about phineas gage the wild
stories about him becoming an
unemployable vagrant can end up
dehumanizing him and we don't want to do
that to people who experience accidents
or brain damage today so keeping in mind
the full life he lived after his
accident can help remind us that
everyone deserves to have their story
told right and the human brain is
incredibly resilient thanks for watching
this episode of scishow psych if you
like learning about the human brain you
are in the right place check out some of
our other episodes to learn more about
how our minds work i really like the one
that we did on how surprisingly smart
