[NewCandle] Nerve impulse through sound?

[Jones Beene]

... 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...?
