OTOH I was visiting my tame biochemist friend today and he is interested
in it as he has always suspected that there was a lot more to myelin
sheaths on nerves than they are usually given credit for. A QM mediated
higher transmission efficiency of signals *might* just be plausible.

 
My theory is that the electrical pulses we see in long nerves are just
chemical refreshes, not the data carriers themselves.

 
That isn't any kind of scientific theory - it is too feeble even to be
called a conjecture. Wild imagining is still far too polite. Crazy idea
perhaps?

 
Consider the timing accuracy required to encode all the information
from your foot, given just the obvious electrical nerve pulses.
 
Now consider what happens to the relative pulse timings when you flex
your limbs and body, when sound and shock waves slam your nerves, when
your heart beats.
 
Too much jitter for simple pulse-time encoding.

 
Who would imagine that it was simple? Design is all about getting the
result you want from the hardware you've got, and while our nervous
system isn't designed, only those random mutations which lead to a
tolerably functional system survived natural selection.

We all know you are a creationist. I was deliberately sending you up
there, and you fell for it.

 
John's idea of 'random' in 'only those random mutations which lead to a
tolerably functional system'
shows he misses out on something essential.
Look at the Periodic System, how neutrons, protons, electrons, combine
in always the SAME configuration
forming our elements...
Nothing 'random' about it.
We know very little what electrons and the other elementary particles
are made of and how those work, are formed, interact.
But starting from the Periodic System that is not random at all and then
all the way to life as we know it
is a pre-determined process that does not need a 'God' / Creator or whatever.
Of course some tinkerer alien could have created the elementary
particles in its lab, but that is circular reasoning.
 
There is  lot of circular things, one can wonder if sort of processes
(like us) exist on the surface of neutrons for example
Not such a wild idea if you see the scale of things, us (as humming
beans) on this planet in this solar system in this galaxy in this part
of the universe we can observe..
Scales are fantastic.
As to 'random' creating a random code is hard, people are trying very hard in cryptology..

 
Johnson and zener noise are random. Scramble several to be really
sure.
 

Maybe logic says we cannot create a random code as we are not random? Wild idea...
But randomness is an interesting thing.
 

 
How about programming a computer to generate random character
substitutions in, say, a Python program, and test various resulting
versions to see if they improve, or better yet, perform some wonderful
new unexpected function.
 
That would be neo-darwinian programming, random mutation and
selection.
 
Actually, that scheme has been tried for circuit design. It didn't
work well.
 
Random mutation and selection does work to design LC filters, up to
3rd order or so. At higher orders, it diverges to nonsense.

If you parameterize using the LC values, I believe that. It’s very
difficult to tune a high-order filter unless you start out pretty close.

Parameterizing f_0 and Q for each section works much much better.
