I suppose that means we need to toss out a lot of data about sodium and potassium channels. Like it or not, you physicists, there is an electromagnetic wave travelling down the nerve, triggering the sequential opening of channels. This is not an energy-free proposition, since a lot of energy is directed to allowing the channels to do their work, and setting up the ion gradients waiting to be triggered by the electromagnetic wave.

That's why nerve impulses travel so much more slowly. And it's not like all these chemical reactions don't create waste heat. Any living organism is giving off waste heat like crazy.

I'll wait for the experiments, but this sounds quacky. I would think, then, that you would be able to ‘hear’ the giant squid axon of lore with a micro-vibration detector.

From article: "a medium with the right physical properties could create a special kind of sound pulse or "soliton" that can propagate without spreading or losing strength." What does the axon do to prevent sound from traveling backwards? How does the body start this sound impulse? And should a human body be immersed into a loud environment, could the environment affect nerve impulses? Death by John Tesh music really is possible! I found another article that goes into slightly more detail. <a href="http://www.huliq.com/13735/action-of-nerves-based-on-sound-pulses" rel="nofollow">http://www.huliq.com/13735/action-of-nerves-based-on-sound-pulses</a> I just need to know which version of nerve impulses will be on the MCAT…
