Because that is useless? The physical phenomenon is so very, very different in biological systems compared to the metal-wire electricity our electrical devices are based on that they are entirely different things.

For example, charge carriers are electrons in metal wires vs. ions in biological systems. That has huge implications, because moving around ions is a lot harder, and slower.

In a metal wire the electrical field is established from beginning to the end, and that means that the electrons at the end start moving at pretty much the same time as the ones at the other end, no matter how long the wire. That means in a metal wire signals move at a significant fraction of the speed of light in a vacuum, because it is the speed of the electrical field and not that of the charge carriers that matters.

In a biological system electrical fields are tiny! The way the signal propagates in an axon is much more cumbersome, expensive, and slow. Speed of signal propagation is ca. 1/2 to at most 100 m/s (for thick myelinated axons). The signal is propagated by jumping in very tiny steps along the axon's inner surface.

This also makes The Matrix movies' main premise about humans as batteries a little strange: Sure, there's lots of electrical activity, but it is in trillions of very tiny places across nanometer distances. And it is created by moving ions around (at great energy cost).

So anyway, what actually physically happens in an electrical grid of metal wires, or in a biological system are vastly different things. It is not the same "electricity", the only thing they have in common is that electrical fields and charge carriers (but different ones) are involved. But the way it is structured, created, propagated is entirely different in both cases.

When I asked Google out of curiosity what it had to say it showed this:

> Despite their differences, both are fundamentally, at their core, the movement of charged particles driven by electrical potential differences.

This is just not correct! The "the movement of charged particles" part specifically. Again, wires have one electrical field, but in biological systems propagation is entirely different, and slow, and expensive! The methods used to propagate a signal are not even remotely comparable. That's a difference not even a Radio Yerevan joke could make use of.

The article notes that bioelectricity is just referring to electricity not occuring in the heart or brain which has a different specialized name. Simply saying electricity is captures more than the cell types reported on.

You're rght. Light? thats just EMF. Infra Red? Emf. Xrays? It's all EMF man.

At least thats ITU regulated frequency bands. I wonder if the ITU regulates biogenic DC signalling frequencies?
