Describes the human brain as a recursive set of cybernetic control systems.
@0.10 in 1947 Weiner defines Cybernetics as "Control and Communicatoins in the Animal and the Machine".
@0.15 "Theoretical Machines", like the von Neumann computer presented at the first Macy Foundation meeting, became emboddied in this modern IBM and every PC. http://www.eingang.org/Lecture/neumann.html
@0.25 From the animal world, networks of brain cells were tested for their computation campabilities by Warren McCulloch and Walter Pitts, two of the Macy meetings' organizers.
@0.40 Belonging to both worlds and the epicenter of everything important to "us", the human brain.
Is the brain a machine? Dr. Norman Doidge says "the brain is not a machine; machines do not grown and change themselves."
However, from the Cybernetics perspective, machines are not things but ways of behaving.
Alan Turing would say that brains are at least "Universal Machines"
Chris Firth says "the brain is a labor saving device" [I ask for whom is it a labor saving device, its owner or the psychopath that deceives the brain's owner?], it consumes 20% of the body's energy, so it must have paid for itself by saving muscle energy.
"Life is change. The brain is a device for recording changes," says Joseph LeDoux [so, human brain is just a recording instrument, not a creative tool?]
Physically, the brain has the consistency of a Jellyfish, which lacks a brain and only has a loosely connected network of nerve cells.
@1.40 Every Neuron is more complex than any computer ever built. We have approximately 100 Billion Neurons in our head, and each one has about 10,000 connections to other Nuerons.
There is nothing in the Universe remotely as complex as the human brain. It has abot 500 Trillion synapses, and by far there are more possible interconnections in our brain than sub-atomic particles in the whole universe.
@2:06 Our brains are a recursive [recursive - relating to, or constituting a procedure that can repeat itself indefinitely] set of cybernetic learning machines, connected by a gigantic feedback loop to the universe itself [so, in others words, our learning is infinite and eminates from external input originating from the "universe"].
Jeffrey Satinover says "the brain is not a single organ, but a verticle stack of them. The newers ones above the older in 'evolutionary order' with the latest out on top." [in other words, our brains are infinitely changeable, with "newer brains" constantly evolving from inputs originating from the "universe"]
@2.44 Our powerful full frontal lobe can even imagine alternative solutions to a problem [hence, this is why vectoring of issues is so critical, as this provides a 'suite' of 'alternatives' for which the recipient can choose when seeking "alternative solutions". It's key that the target not be allowed to develop homegrown "alternative solutions," for these have not been planned for in the Cybernetic feedback loop system].
How do brains supplement their regulatory capacity beyond what the genes gave them? From random sources and from the environment itself, says Ross Asby.
[Ross Asby on page 271 of Introduction to Cybernetics" says "Whence [From where] come the supplementation?" Below is the actual passage from Ross Ashby's 1957 book:
Whence comes the supplementation? From random sources as
in S.12/15 and from the environment itself! For it is the environment
that is forced to provide much of the determination about
how the organism shall act. Thus gene-pattern and environment
both contribute to the shaping of the fully developed adult, and in
this way the quantity of design supplied by the gene-pattern is
supplemented by design (as variety and information) coming
from the environment. Thus the adult eventually shows more regulatory
capacity than could have been determined by the
gene-pattern alone. The amplification of regulation is thus no new
thing, for the higher animals, those that adapt by learning, discovered
the method long ago.
May it not be possible that the amplification can be increased
even further? If so, is there not a possibility that we can use our
present powers of regulation to form a more highly developed
regulator, of much more than human capacity, that can regulate
the various ills that occur in society, which, in relation to us, is a
very large system?]
@3.06 Neurons evolve from skin cells some 500 Million years ago and have specialized to detect a dozen different sensations. Brain cell interconnectedness is controlled by regulator ["regulator " - this is a very important term that is used in Cybernetics] genes. They send if-then instruction to the genes in charge of directing the growth of axons. When axons reach their target they get the signal to stop growing.
Brain cells of a baby in the womb multiple at an alarming rate as ("alarming"... really?) neurons compete for connections, as axons reach exact locations neurons that do not meet their quotas promptly commit suicide [so, this is what's being used as a model for "regulating" human population] and glial cells do the cleanup.
"So-called programmed cell death is one of the regressive events that help shape the final pattern of connectivity"
~ Joseph LeDoux, Synaptic Self (p 81)
@3.43 Neurons are myalin insulated. A signal carrying electrical impulses through the axons release neurotransmitters captured by dendrites located on the cells main body. The use it or lose it rule starts applying at this level. Synapses need strengthening for better performance. Practice makes perfect.
@ 4:07 Cells that fire together, wire together. Neurons form circuits, and circuits form systems.
~ LeDoux (p 79)
[Hence, Internet connected humans form subsystems, or subgroups of like-minded people, easily targeted as groups via propaganda]
@4:12 Thanks to high redundancy and smart layering these systems produce intelligence [does he mean "new knowledge" here?].
~ Joseph LeDoux (p 87, 96)
@4:17 Learning produces a synaptic result: memory. But without memory there is no learning. Solving this paradox generates a beneficial positive cybernetic loop: the more you learn, the more you can learn. [Hence, the public's collective memory is being confused and destroyed via propaganda, inhibiting the public's ability to collectively learn]
@4.34 This is what an active Synapse looks like. Learning depends on dopamine producing neurons rewarding sucessful synapse creation. Drug addiction ruins dopamine channels.
"You are your synapses"
~ Joseph LeDoux
People are glued together by life [In other words, we are a mass-collection of synapses]
@4.52 Winning & Losing Synapses [ie People]
Contrary to popular belief, learning a new language involve losing some synaptic connections... adding, strengthening and keeping the ones needed for the specific job [this is synonomous with keeping only purpose-built humans in society]
~ Joseph LeDoux, Synaptic Self (p 74)
Older folks have trouble even isolating a sentence spoken in a foreign language. [I guess since older folks have trouble creating new synapses they should undergo "programmed cell death"?]
@5:11 Large systems of neurons are compulsive mapmakers and model makers. Our bodies, our posture, our location, our room, our house, even our possible actions, everything gets mapped. [he's talking about framing, as this is how we perceive our world. Propagands is key in creating these framed views]
We use this illusory world [Simulacrum] to make sense of incoming signals. [hence, we filter all inputs based upon our specific framed view, discarding or discounting inputs that do not make sense in accordance with our particular frame]
This works to create a negative feedback error controlled prediction loop that improves with repitition." [again, our ability to frame improves, reducing error. But what is error, error is merely inputs that do not align with ones given set of frames. So, the more embedded ones framing, the harder it is to break out of it. Voila, and there you have a perfectly prgrammed human]
~ see Chris Firth, Making Up the Mind (p85)
@5:40 The fact is that perception is controlled by our current internal maps [in other words, our unique brain's system of neurons create our perception that results in the frames by which we view our reality].
Perception is a loop. [Hence, perceptions is subject to the laws of Cybernetics, and can be modified through cybernetic techniques]
Plenty of cognitive emotional and motivational processes that we are unaware of, underly our consciousness. [ie we are not aware of all that forms our map of frames. Hence, we are not aware of the frames that we possess and view reality through.]
To a large degree, culture determines what we can and cannot perceive. [Culture creates our frames of perception]
~ see Chris Firth, Making Up the Mind (p85)
~ see Joseph LeDoux, Synaptic Self (p 259)
~ see Norman Doidge, The Brain that Changes itself (p399)
@6:00 New cognitive systems are patchwork and modifications of old. [they are creating a new cognitive system now, and they call it the Global Brain]
~ Gary Marcus, The Birth of the Mind (p132)
@7:56 Artificial Life research and Complex Adaptive System (CAS) at the Sante Fe Institute will help study how collective brains work [There's confirmation right there that they are working on a techniques for forming a Global Collective Brain]
~ see Chris Langton, Artificial Life & CAS
@8.07 Is the mind the product of the brain?
What about recent discoveries that the contents of the mind shapes experience and experience shapes the gene expression that shapes our brain?
~ see Norman Doidge, The Brain that Changes itself (p213)
~ Gene duality: see Gary Marcus, The Birth of the Mind (p59, 148)
The Cartesian (see René Descartes) body-spirit duality continues to be an appealing metaphor.
@8.24 Even genes have a dual nature. They are templates for protein creation and also a guide as to when and where that protein should be built. Computers and Software. Brains and Minds. Do-ers and Managers.
@8.40 These three outstanding Cyberneticians saw the brain as an intermediary between the real world and ourselves. Consequently, the cybernetics scientific embraces this kind of relativity.
According to Ashby's definition, systems are lists of variables we isolate, not objective facts. [Hence, we create systems, they are not objective].
We see with our brains, and with our minds, and not with our eyes. [in other words, we interpret everything and create our own realities through this interpretation].
~ see Norman Doidge, The Brain that Changes itself (p15)
@9.05 Just as every culture from the dawn of our species has perceived the World musically and linguistically, every culture has perceived the world spiritually.
~ see Mathew Alper, The God Part of the Brain (p6)
@9.25 We still ignore a lot about how the brain works. Is our brain a quantum computer that allows us to transcend our mechanicality?
The human brain is the universe's bigges achievement only possible on a planet like earth and just the right size too. Maybe the purpose of the universe is to contemplate its own existence through us. It has about 7 Billion brain from where to choose from.
~ Jeffrey Satinover, The Quantum Brain (p7)
