The New Scientist had a very interesting article on the Gut Brain recently. The same sort of cells that make up the brain
– the neurons - can also be found throughout the rest of the body, the spinal
cord being an obvious example. What is
less well known is that the human gut contains 500 million neurons – about as
much as a cat brain. This Gut Brain
operates largely independently of the Head Brain, and I suspect is by far the
older. 90% of signals go from the Gut
Brain to the Head Brain. When the
connection to the Head Brain is severed, the Gut Brain can continue its work
independently. It plays an important
part in repairing tissues and bones, and the signals it sends to the Head Brain
have a strong impact on moods and desires.
I am not going into details, because they are technical and
can easily be found elsewhere. The
important point is, in my opinion, that a person is a lot more complicated than
we think. We are not just a
computer-like brain lording it over a car-like body. Rather, the Head Brain is simply the biggest
conglomerate of neurons in the body. There
are subsidiary centres in the guts and in the spine, and smaller outlets can be
found throughout the body. Including all
our organs …
A further complication is that, as maintained in a previous
post, there are trillions of bacteria and other micro organisms in our bodies, mainly in the gut but also
everywhere else. Most of them are not
‘foreign bodies’ who can be dismissed as free-loaders or aliens – they are in a
symbiotic relationship with the rest of our body-cells and contribute to its
success or failure. Indeed, I think it
makes little sense to view them as separate from the rest of our body-cells. They are a part of us, just like all the
other cells that make up the cosmos that is our body.
A body is a supremely integrated mechanism, where all parts
constantly interact with each other. Any
change will affect the entire system, even if this is not always immediately
obvious. Just as a change in diet will
affect mood, sleep patterns, skin texture, concentration, etc, so will a change
in mood affect sleep pattern, desire for particular foods, etc. To focus on one aspect of the body/person to
the exclusion of all others may be a convenient approach to a particular
problem, but will ultimately fail because of its reductionist nature.
Personally I find it absolutely amazing how all the
different bits of me, cells and neurons and bacteria and other assorted micro
organisms work together so well, despite all having their own unique individual
life-goals and objectives. They are like
the citizens in a state, all working together for the common good.
In light of this it strikes me as ridiculous to decree that
when the Head Brain no longer functions everyone else, all the bacteria and
other micro organisms, not to mention the various subsidiary brains and organs,
can just be cut out and implanted in another, equally complex, human body. These are not spare parts, to use in any way
a medical team sees fit. It is all very
well for the Head Brain to sign up as an organ donor, but s/he is donating
something that is not hers/his to give.
It seems much more dignified, and kind, to let them all
adjust to the new situation after Head Brain has died. There may be a period of mourning, of letting
go, and then some micro organisms will also die and others will leave the body
and join another one, when they are ready and as they see fit.
Lastly, the argument I keep hearing is that it is selfish
not to donate one’s organs to save or improve someone else’s life. Well, and what about donating one’s
money? If it is silly to love one's body even unto death, surely it is much sillier to love one's material possessions?
PS I appended this post with the following Reader's reply to a newspaper article, which I found very moving:
'Everyone and every situation, is different... For some, it helps them through
the pain, for others it does not...
Until you have actually been in a
"survivors" shoes, no one can really understand all that is involved, both
emotionally and physically. As opposed to what the article is talking about, the
one who has died, or is dying, is NOT the real issue (in my opinion) with orgran
donations.
Twelve years ago, my late wife and I were either organ
donors, or had discussed it and knew that both of us wanted it done. It sounded
like a great and honorable thing to do. We knew nothing about the actual process
involved...
One evening, my wife suddenly, with no warning, suffered a
massive stroke / burst anurism (sp). Rescue came and we were transported to the
closest hospital within ten to fifteen minutes. They were unable to do anything
for her, other than to "keep her alive" and transported her to a major trama
center by life-flight. I was driven by a friend.
An hour later, we made
it to the hospital and were told she had a 1% chance of survival... Essentially,
none. She and I had never discussed "percentages", or who and or what makes that
decision. While waiting for our daughters to make it to the hospital (one was on
her honeymoon), I was approaced by the "organ harvest team leader". Since my
wife and I had discussed this, I said yes... What do I need to do...
I
was presented with 17 pages of documents I had to sign and "pressure" on the
time... Every minute / hour eliminated the possibility of anyone using more and
more organs. I simply "HAD" to wait for my daughters to arrive, so they could
say good-bye. The machines kept her body "alive".
The "process" that
would be involved was "scary"... The Dr. said there was only the slightest of
chances for survival... but they can never say, no chance. We would not know,
for sure, until her heart and breathing actually stopped, after turning off the
machines. BUT... if you are doing organ donation, they do NOT turn off the
machines, until all the needed organs are removed. A big "empty" question-mark
hit me, like a ton of bricks.
If we go with the organ donation, we will
never know if "we" killed her, or if she had already (actually) died. Given
everythng going on, at that moment, none of us could say "yes"... We "had" to
know if she was going to make it, or not.
"I" turned off the machines at
8:17 in the morning... Her daughters stayed for awhile, I stayed throughout. It
took 23 minutes for her breathing and heart to stop... I stayed, holding her
hand, talking to her, for the longest 23 minutes of my life.
Within 5
minutes, the "organ harvest team leader" was back with me to discuss tissue
transplants, since they can not use organs, after the patient has officially
died. Again, I discussed it with our daughters and we said yes... up to the
moment they explained that it would take up to a week to accomplish and there
would be no funeral, etc. until afterwards.
It was simply impossible for
anyone to agree to, at that time. None of us, not myself, our daughters, my
father, her sister, or cousins, etc. knew any of this, knew what was involved,
or how it would feel to those of us, left behind. To all of us, right, or wrong,
the funeral was important, the laying to rest, essential for saying good-bye.
Today... I am married again. My current wife and I have discussed all
this and I "may" react differently, this time, should a similar situation come
up. At least we have "said" we would.
So... Until you have been there,
until you are sitting there, holding your wife, or husband, who you have loved
dearly for 12 years, in your arms, as they slowly pass away, please do not get
all "preachy" towards me about what is the right, or wrong thing to do, with
their body. Until you do so, you will have no idea how you will feel, at that
moment.'
Judging by other comments this experience is neither unique, nor universal. But it shows the disrespect we have developed for death and the dieing person.
