OTOH I was visiting my tame biochemist friend today and he is interested

That isn't any kind of scientific theory - it is too feeble even to be

Consider the timing accuracy required to encode all the information

Now consider what happens to the relative pulse timings when you flex

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.

There are objective tests for electronic design.

These are objective tests for the quality of the circuit that has been produced. They don't say anything about the process that lead to the selection of that particular circuit.
If you can't say why you did something in a particular way - and you never do - you can't claim to have designed it.
Inspired designers may sometimes get things right first time. Most designers rip up any number of first tries at a design before coming up with an approach that can be made to work reasonably well. You don't tell us about your false starts.
Sometimes those those false starts can become practical when the technology moves on - I thought up one scheme in 1976 which didn't become practical until 1993 (when I got my hands on a big-enough cheap programmable logic device) and it shows up in my 1996 milli-degree thermostat paper (section 2.6).
