Interesting: Nerves Running On Sound
Just a theory, but it sounds pretty interesting (no pun intended, of course)
“Anesthetics, they suggest, lower the temperature at which lipids become solid, making it difficult for the waves to form, thereby preventing nerves from sending pain signals. They also suggest that as the waves travel, they change the shape of the cell membrane, producing the electrical pulse that scientists currently mistake for the primary function of nerve cells.”
