- The human brain, is a challenge
for physics to explain down to the level of quantum mechanics. At the same time into meta physics and deep
into philosophy. (Metaphysics = abstract
theory with no basis in reality.) We are
navigating the narrow path between solid ground and the edge of a swamp
-

-
----------------------------------- - 2151 - The
human brain
-
- Science is
supposed be the tool that describes our natural world. Things are not all black and white, not all
1’s and 0’s. The natural world lies between
the digital and the analogue. We are just
learning that even our brains have figured this out. Whether we realize it or not.
-
- Your brain
was thought to work like a digital computer with the neurons being a network of
switches snapping on or off. Science
knew that these dendrites were long branch-like structures attached to a
roundish-body called a “ soma”. Together
they formed the neurons which made up the switching network.
-
- The dendrites
were thought to be the conduits that carried a spike of electrical activity
sent to the other soma of other neurons.
What we are now just beginning to realize is that the dendrites are “
active”, not just conduits. They are generating
their own spikes of electrical activity.
-
- Dendrites
make up over 90% of all the neural tissue.
They are 10 times more active than we thought. This discovery changes the whole nature of
our understanding of how the brain computes information. It is operating as both a digital and an
analog computer.
-
- Dendrites can
put our longer lasting voltages that in their sum total actually are more
powerful than the spikes of the somas.
The brain just does not work with all or nothing signals. It also
processes analog flows that affect computing.
-
- Dendrites are
hybrid cells doing both digital and analog computing at the same time. The are generating digital pulses and large
analogue fluctuations at the same time.
They are 100 times larger in volume than the somas. Does that mean that our brains are 100 times
more powerful than we thought. ( It is
ironic to me that we are here thinking about thinking. It is a strange closed loop to be in. Like staring at our navel and thinking where
did that come from?)
-
- A study made
on lab rats found that dendrites were 5 times more active when the rats were
sleeping . And, 10 times more active
when the rats were awake and moving.
-
- This all
tells us that learning takes place with much more “ flexibility” than we
thought (thinking about thinking again).
This whole revelation is changing our understanding of how the brain’s
neurons actually work.
-
- This science
gets us closer to how the brain works philosophically. It gets into the question of how does the
brain have a conscience? What is
conscientiousness? What creates it?
-
- Materialism
is the idea that all phenomena is
reducible to the behavior of matter, to physics. The mind is simply computing using meat.
-
- Ontological
is the branch of the metaphysics that studies the nature of existence.
-
-
Epistemological is the branch of philosophy that investigates the
origin, nature, methods, and limits of human knowledge.
-
- We now are
dealing with the intersection between science and philosophy.
-
- The brain
might possibly be explained in terms of matter down go the weirdness of quantum
mechanics. Or, it might it might
explained by Newtonian physics operating in a complex information operating
system. Could the mind be simply
biological?
-
- The
relationship between the mind and matter?
It is difficult to convince us that the mind is purely a biological
phenomena. Maybe quantum phenomena
occurring in the brain are the root of our conscious experiences?
-
- Maybe only
God can fill in the gaps in our argument between science and philosophy. We still like to believe that the design
would not have required any supernatural intervention.
-
- Our job of
thinking about what science has learned about the world and what meta physical
theories are telling us will wander from solid ground into the swamp.
-
- Mans conscience
is the oracle of God. An oracle is a
person considered to provide wise and insightful counsel, and prophetic
predictions
-
- It is far
more important to preserve an unblemished conscience than to gloat in
accomplishments.
-
- There is no
dungeon so dark as one’s own heart.
Conscience is the voice of your soul.
-
- There is not
witness so terrible, no accuser so powerful, as the conscience that dwells
within us. Conscience warns us as a
friend, before it punishes us as a judge.

-
2078 - Be thankful for your brain. It took 1,500,000 years of development. No other brain cooks its food.
-
-
1999 - Brainology mindset. A trick played on students was too convince
them that the neurons in their brains formed new connections every time they
stretched their brains to failure. Over
time they would automatically grow smarter.
This is called the Pygmalion Effect.
-
-
1998 - Understanding yourself. If the brain were simple enough to understand
we would all be too dumb to figure it out.
-
-
1962 - The human brain is a challenge for physics to
explain down to the level of quantum mechanics.
-
-
1610 - Be thankful for your brain, cooking made us
human. This Thanksgiving be thankful for
the calories to power it.
-
- 1405 -
What makes your brain conscious.
How does a brain transform itself into a mind? If information processing is the key to
consciousness could the internet ever create consciousness?
-
- 1403 - How
to become an athlete? The key o
greatness as an athlete is to train your brain to keep calm and stay
focused. Free your mind and the rest
will follow. Your brain will take over
your actions.

Brainology mindset. See Review
1999.

The brain works. Everything the brain
does is to try to minimize prediction errors. One adaption effect is the neurons stop firing
after prolonged exposure to a stimulus. Like
the wife nagging you.
-
- 922 -
Understanding yourself. Serotonin
is the brain's don't worry, happy chemical. Noradrenalimn is a biochemical having the opposite
effect. The right half of the brain is in
charge of visual and spatial thinking. The
left half is in charge of speech.
-
- 868 -
Seeing with ½ your brain. You may
think thinking is hard , but, seeing is much harder. Computers can do a lot of things better than the
brain can. A lot of what we see is recognized
because the image is already in memory.
-
- 801 - The
brain. What was your memory just before
you became conscious of it? With your dreams
you can actually see things with your eyes closed. Your brain is what makes you you, be careful what
you feed it.
