Phineas’ Life Goes On
1851-Phineas
comes home and works around town at a stable.
Early 1852-
Phineas meet a man who said he wants to have a stagecoach line in Chile, so
spontaneously Phineas just says goodbye to New England and began a life in
Chile as a stagecoach driver.
1859-
Phineas goes to see family in San Francisco. He gets a plowing job for a
farmer. Soon after he comes to San Fran, he experiences many seizures, (known
as epileptic seizures.) Doctors tried to “bleed” Phineas or reduce his blood
pressure by taking blood, to help the pressure on his brain, but this does not
help the seizures. It is unknown exactly why he experiences them, maybe it’s
from his accident before, maybe he hit his head again, or maybe he had an
infection, it is unclear why, but them constantly occurring wears Phineas down
and he passes away on May 21, 1860.
1862-Paul
Broca a French surgeon from Paris discovers something new about the brain. He
examines brains of people who experienced strokes and lost speaking ability. He
then became aware of an injury in a certain spot on the brain located by the
left front lobe. This is known as the “Broca area” found just above your left
ear hole, two inches in front. Trauma to this area may cause you to not be able
to speak ever again. Not long after, a man named Carl Wernickle who was German discovers
another area of the brain that is in charge of interpreting speech. This area
is found by the left temporal lobe and if damage it could hurt someone’s
competency of apprehending speech. As you can see brain science slowly begins
to develop and become clearer.
Following Phineas Gage
Phineas
Gages story ended up at the “P.T. Barnum’s American Museum”, located in New
York City on Broadway. This was no ordinary museum. This was a museum of the
unthinkable; people would come from all over just to see. The museum included
things such as “mermaids”, “bearded ladies”,” living giants”, bizarre animals
and creature’s people just wanted to see for themselves. Among these things
were pictures and models of Phineas’ head and explanations of what happened. At
times Phineas himself would be presented at the museum with his tamping iron.

What we thought about how we thought- The Brain
In January
1858 and Dr. Bigelow goes to Boston to speak with and let doctors examined
Phineas. They make a mold of Phineas’ face and discuss what happened and why it
happened. Dr. Bigelow speaks with doctors and sort of makes a presentation about
Phineas’ accident. Two main accumulations of doctors are intrigued by what Dr.
Bigelow present. They come to their own conclusion of what happened and how it
happened.
In the 1800s
Franz Joseph Gall an Austrian Dr. makes the statement that intelligence and emotions
are centered in the brain.
Long, long
ago people said they “knew” emotions center in the heart, and the spleen
controlled anger, and to me this is silly how nearly 300 years ago people said
they “knew” for sure this is what happened in our body. Our thoughts about the
body have changed just a bit.
In 1850
doctors however didn't know a lot about our body, they knew we had certain
organs, they knew the skeletal makeup, but they were unclear about the brain
exact functions.
The brain is
covered by your cerebral cortex. Your daily functions are kept going by your
brainstem, which connects into the spinal cord. The cortex is where all your
emotions develop. You also remember, dream, speak and think in your cortex. You
also experience your five senses in the cortex. All these things occur in your
cortex, in the brain.
In 1850 doctors did not know much about cells, nerves, and
neurons that were contained in the brain and spinal cord of the body. Messages
and signals are transmitted through a person’s neuron. This was all unknown to them
at time.
The two
types of doctors examining Phineas each had very different thought processes.
The one group referred to as the “Whole Brainers” thought the brain was a whole
or one, and it was all connected somehow. The second group referred to as the “localizers”
thought the brain was split into different sections and each section had a job.
They thought specific “Organs” located in the brain were in charge of certain
functions that occurred. They said that the “Organs of respect” and “kindness” were
found right above the left eyebrow, which was where Phineas was struck, (They
thought maybe this is why he has been acting different lately.) This group of
doctors or “Localizers” found that the brain has 37 “Organs.” They concluded
that if you have a strong organ, your skull will come out a little. If you had
a week organ the skull will be indented in that spot. For example if your “Organ
of Amativeness” has a strong bump after it then you have strong physical love.
This thought process is known as phrenology. However the “Localizers” were
incorrect about the “Organs” found in the brain, but they were correct about “Localization.”
And as far as the “whole Brainers” thought process, they were incorrect about
the brain as a whole, but correct about how it is all connected.
The brain does
have many different functions found throughout the cortex which has many parts.
The cortex allows you to pick out certain things, walk, and allow you to
perform many other different tasks; it is all possible because of this part of
the body which is found in your brain.
What we thought about how we though- Doctors of the 1850’s
Doctors
during this time period were said to have dressed like proper gentleman. Lots
of pictures were painted of them to make them look extra good. They had cleaned
cut shaves, gold jewelry, expensive looking clothing, or jackets, and
especially looked smart. Although lots of pictures were made of doctors, there
were not many pictures of him doing anything like performing any operations or
examining any patient's. This was because back then it was hard to take a
picture of a moving object, no one really had the right equipment to focus in on
and take a picture fast enough of any object in motion. A man named Josiah
Hawes from Boston was probably the first to take a picture of doctors
performing tasks that make them doctors. Back then only males were doctors and
many times when they performed an operation or examined a patient, rarely any
of them wore gloves, masks, or scrubs. No protective gear was included in these
pictures.

Ten Weeks Later
Phineas’
recovery was remarkable after ten weeks. He then decided to go to New Hampshire
to see his mother, and then returned back to Cavendish in the spring. Phineas
is still able to speak, feed and dress himself, but he has trouble seeing out
of his left eye and has a couple of scars, he is still not the same.
Dr. Harlow
writes an article about Phineas’ case, and it was very appealing to a professor
at Harvard, Henry J. Bigelow. He tells Dr. Harlow he wants more information and
eyewitnesses that say this accident is really true.
After
Phineas returns home in the spring he goes back to work. But he is different.
He comes across as a mean, angry man that you can no longer rely on. He seems
mad, he yells and acts very rude to people. So Phineas’ is fired from his job.
Dr. Barlow observes and writes comments on how he behaves, but he does not
share them with anyone, he is not allowed to unless Phineas gives him
permission.
Fourteen Days Later
Fourteen
days after Phineas’ experience with the iron rod, he began forming abscesses, a
fever and he was no longer hungry. So Dr. Harlow continues to care as best as
he could for Phineas and once again miraculously Phineas was okay and
everything was healing normal. Dr. Harlow saved Phineas’ life. Phineas however
was not staying in bed and was not listening to Dr. Harlow's orders so he gave
him two prescriptions that were very strong and would help clean out his
stomach and bowels, and basically forced Phineas to stay in bed, and that's
when he finally did.
Louis Pasteur and Joseph Lister
At the time
of 1848 Louis Pasteur, a Frenchman was in the process of examining and
researching fermentation, infection, and decay, which are all caused by “germs
“as Pasteur called them.
Joseph
Lister who was an English surgeon was motivated by Pasteur’s theory about “germs.”
Lister wanted to conduct surgery only under conditions that were sterile or
clean. He began boiling his medical instruments, and cleaning his hands and
clothes thoroughly before performing surgery, because of this man’s sterile
procedure before surgery, in 1868 deaths caused by infection were reduce
significantly.
Even though
this information is useful now, it was unfortunately, unavailable and was
unknown at the time of Phineas Gage’s accident. So Phineas’ Doctor, Dr. Harlow
did his best to keep Phineas’ cut clean and hidden.
How much did people really know in 1848?
Even though
it was then that Englishman Robert Hooke came up with the basic unit of life, cells,
and the first to examine single-celled organisms closely was Leeuwenhoek, a lot
was still unknown about bacteria at the time.
In 1848 the
word infection was never used by doctors. However they knew if someone had an
infection or not. They referred to it as a “septic” wound. However doctors
didn't really know much about gangrene, fungus, viruses, streptococci,
staphylococci, doctors were not cautious of bacteria laying everywhere, on
their medical instruments, on their hands, or even in the air.
An open cut
allows bacteria inside it if not treated correctly. Once bacteria is inside the
body the body's immune system fights it and the bacteria fights back by
releasing chemicals that are toxic to the body, this war between bacteria and
the immune system is known as an infection.
“Horrible Accident” in Vermont (Part 2)
Phineas Gage
made his way into town after the accident without a problem; he was still
surprisingly conscious, and continuing to talk to everyone about what had just
happened about 30 min. ago. Can you just imagine walking by and seeing a man
covered in blood with a hole through his head, but yet still alive and talking
to people as if nothing was wrong? To me this is crazy and seems unreal!
At this time Dr. Edward Williams arrived at the hotel Phineas was waiting at. He asked the people around and the workers that assisted Phineas what had happened (since he figured Phineas was a little out of it considering how he looked) but Phineas demanded to tell the doctor himself. After Dr. Williams examined him Dr. John Martyn Harlow (the regular physician from that town) takes over. He helps Phineas inside and then begins to clean his wound. Dr. Harlow does the best he can to wrap and clean off Phineas’ head wound, and he realizes Phineas’ arms are burnt, so he begins to wrap them as well. The doctor is surprised that Phineas is alive and survived this open brain injury. Phineas should have died instantly, but didn't. Phineas should have died from all the blood he lost, but didn't. Phineas should have died from his brain swelling, but didn't. How is this all possible?! Can anything else go wrong?!

“Horrible Accident” in Vermont (Part 1)
The question lucky
or unlucky is always asked when talking about Phineas Gage. On September 13,
1848 Phineas Gage’s life was turned upside down from that day on, and it will
never be the same. Phineas was only 26 years old and worked as a railroad
constructor in Cavendish, Vermont and at the time, this job was very strenuous
and hardworking. There weren’t any machines to help out the human hands.
Phineas had a special talent at the construction sites, he blasted! His job was
to blast rock that was in the path of work. In order to do this, Phineas needed
a tool called the “tamping iron.” This was used to position explosives. It was designed
to have one end for pressing down on the powder and the other end was very
sharp to set the fuse through the gun powder.
Gunpowder is very sensitive when it is dry, it
could go of at any moment, and it did! Phineas was getting set up as usual but the
fuse is left exposed by accident and Phineas had got distracted and the fuse
was set off! The tamping iron soars through the air and the Phineas fly’s
backwards. The rod had passed right below his left cheek bone, going behind his
left eye then in front of his brain. Surprisingly Phineas gets up and sits on a
cart to be taken to the doctors and the whole time Phineas talks to everyone
and is describing what just happened and why there was a hole in his head and
blood was gushing down his face.

I chose to read the book, Phineas Gage: A Gruesome but True Story About Brain Science by John Fleischman. This book is about a man named Phineas Gage who was a construction worker on railroads, and one day he had a terrible accident with a metal rod that had passed straight through his brain. He surprisingly lived and now this accident has helped others understand how the brain functions exactly.
