[NewCandle] Nerve impulse through sound?

[Keith Nagel]

Getting down into the muck a bit...

http://en.wikipedia.org/wiki/Action_potential

It's interesting that, if you buy the equivalent
circuit model presented, then there should be
some losses which would measure as heating
of the nerve channel. Presumably, this is
what the authors claims isn't happening.

I sort of understand what you're saying; the
conduction process does seem a lot more "sound like"
than what we're used to with wires and electrons.
I know from prior experiments that an actual
electrical impulse would move along at speed
C in either system, and I know Horace also experimentally
measured this with a long tube of salt water.
The electrical part then is more byproduct than cause.
In a wire, it would be as if the signal was carried
at the drift speed of the electrons rather than C.

Also, it amused me that the system is also a negative
differential resistance at threshold ( see the VI chart
at the link above ).

... a semantic alternative to this argument, and it may be what you are 
getting at, Keith, is that the wave propagation in a neuron, although 
having some features of "sound" [in that phonons physically move] - is 
also "electric" in that when kinetic energy acts to force the 
near-fields of ionic conductors closer together, and then further apart, 
there is a similar propagation of emf as to that in a metal wire --but 
without electron drift --

...this method is not the same as "electricity" through valence 
electrons, where there is electron drift, but electron movement is 
itself NOT a prerequisite for electrical energy transfer (i.e. a 
battery). I would cite Bill Beaty's nice essay if I were not so lazy, 
but I know everyone here has read it anyway.

OK... how is that for wording an answer which is 
neither-either-nor-neither...?
