Neurology: codes between neurons, a complete mystery !!




by dedeleco » 07/07/11, 15:33

since Christophe asks:
Dedeleco, your message should be the subject of a subject all by itself! It's way too important!

I've always been taught that there's nothing else going on between neurons ... only nerve impulses, so electricity, so electrons ...

https://www.econologie.com/forums/post207648.html#207648
I reproduce my information among the unexplained but unobserved phenomena:

Not explained, and decoded, the meaning of signals between two neurons !!

There are mysteries that are very real and much more studyable long before we think or dream of the hereafter, which is based only on testimonies, which can be completely false, like the words or orders that schizophrenics claim to hear. !!
http://fr.wikipedia.org/wiki/Schizophr%C3%A9nie
http://en.wikipedia.org/wiki/Schizophrenia
For example, voices and other religious appearances are very likely schizophrenic manifestations that do not derail enough to be so recognized, especially formerly.

Also among the mysteries of observed and unexplained phenomena, it is crucial long before, to understand the detailed functioning of the brain, which is not understood despite what science has already discovered!

Thus the communication code between two neurons remains totally unknown and we do not say it !!
We measure signals, electrical, chemical, but we don't understand anything, absolutely nothing !!
Even between 2 isolated neurons, we do not know what they are saying, if it is rudimentary as for a flip flop of two transistors of a computer (idea taught very insufficient and therefore false) or if it is much more complex with a very complex code between each neuron, electrical and chemical ,, communicating a whole complex picture as experiments show by activation of a single neuron when viewing a precise complex image !!

We don't understand anything about these signals between 2 neurons !!
It has been found that the moment of relative triggering of the pulses between neurons is very important and that it is not just ordinary binary signals all or nothing, as on a computer, but we understand nothing, strictly nothing, to these signals, which also carry chemical signals, with nearly 300 neurotransmitters!

So before looking at our bizarre impressions, it is essential to understand the bases of communication between 2 isolated neurons, which currently are an observed phenomenon but unexplained and indecipherable for more than 80 years that we roughly measure them !!

Our neurons have a communication code, much more unreadable than the code of our bank cards !!

we never talk about the meaning and real code of these signals !!
http://fr.wikipedia.org/wiki/Synapse
http://fr.wikipedia.org/wiki/Neurotransmetteur
http://en.wikipedia.org/wiki/Neurotransmitter


If you type on google: neuron code
you will not find anything about the actual code of communication between neurons but that fake models on neuron network computer, too simple compared to real neurons !!

In my opinion each neuron has a very complex thought, detecting a single complex image, or concept alone !!

An example of speculation without experimental proof on the different types of coding imagined, which has the merit of admitting our total incomprehension:
http://books.google.fr/books?id=GxAlCMO ... de&f=false

More with the mystery even thicker the importance of the gaps between pulses. :
http://books.google.fr/books?id=dzyy3Xl ... de&f=false

A slightly more realistic model in this total mystery:
http://audition.ens.fr/brette/papers/these.pdf

So before studying globally, it is essential to understand this mystery of the communication code between neurons, same as flies or worms!

More generally, the communication between living cells is very complex but essential and also a memory of more than 2 billion years of monocellular evolution communicating enormously with the eyelashes and chemically, essential for the development of our organs
Cancers are also a broken communication between cells.

The genetic code of life seems understood but it is a false impression, because in fact much more complex, with code in the code, microRNA and epigenetics and many mysteries yet to be discovered.

The literature on this subject of life is immense, without solving these mysteries. !!!

Thank you, it will be more visible as well!

So we all have a quantum computer in our heads? : Cheesy:

Well there I admit, in neurology, mine is a little ... a lot ... : Cheesy:

According to the title of the .pdf of the ens "impulse model" and what I understood from the "summary": the neurons would therefore make a hope of ... evolved walrus?

A current example of the total mystery how neurons communicate:
Neurobiologists Find that Weak Electrical Fields in the Brain Help Neurons Fire Together
http://media.caltech.edu/press_releases/13401

And therefore cell phones disrupt our neurons well below legal limits !!

An "unexpected and surprising finding was how already very weak extracellular fields can alter neural activity," he says. "For example, we observed that fields as weak as one volt per meter robustly alter the spiking activity [firing] of individual neurons, and increase the so-called 'spike-field coherence' "- the synchronicity with which neurons fire. "Inside the mammalian brain, we know that extracellular fields may easily exceed two to three volts per meter. Our findings suggest that under such conditions, this effect becomes significant."

What does that mean for brain computation? At this point we can only speculate, Koch says, "but such field effects increase the synchrony with which neurons become active together. This, by itself, enhances the ability of these neurons to influence their target and is probably an important communication and computation strategy used by the brain. "


Another attention effect that makes neurons more synchronized:

primate somatosensory cortex

http://papers.klab.caltech.edu/197/1/388.pdf

but still we don't understand anything about this collective dance of neurons !!

Hold these V / m remind me of this famous experience known to everyone: the electrical stimulation of the brain (on the surface) of a conscious patient (open skull therefore and brain in the air).

According to several testimonies, the stimulation of certain zones made them relive certain memories in a very precise way, much more precise than the "classic" memories. That is to say with "any" smell, detailed sounds ... (at the "matrix" what ...)

It is an index of the extraordinary capacities (under exploited because very little known) of the human brain ...

Imagine, 80 years ago, being able to relive selected moments from your childhood or youth with a small device that you would put on your head at brainstorm? https://www.econologie.com/forums/post205222.html#205222
