Brain Waves

I’ve tried looking this up, but I’m having a hard time. So I come to you, the geniuses of this world :smiley:

Brain wave activity is, and has been measured, but have electrical impulses been measured in ohms, amps, watts, volts, etc…?
If so, what is the average ohm, amp, watt, or volt?

Also, an optional dorky question. Back when I use to believe that telepathy was possible (before I knew that it was psudo science), I never heard the theory for how people believed this happened but made a theory of my own. I figured that it must have somehow had something to do with sending out electrical impulses from one persons brain to another.

Just out of curiosity, strong would a brain wave in order for such a thing to be possible?

Thanks.

The units of neuronal communication are action potentials. Action potentials are impulses that travel down the length of the axon and cause the release of a neurotransmitter to trigger a response in another neuron across the synapse.

A single action potential is about 40 millivolts. The electrical activity (brain waves) that instruments pick up is the sum of billions of neurons firing at variable rates of a few to many times a second (all neurons fire, even when at rest).

Here is much more detail:

40 millivolts, thans. I’ll check out the link.
