However the question was whether there is electric current in the human brain, you claim there is not. Electric potential (volts) seem to indicate that there is current.
From my previous link;
What do the words "electrical activity" mean? I wouldn't think it means potential.
(EEG) is the measurement of the electrical activity of the brain
Does the human brain produce electricity?

Your brain generates enough electricity to power a lightbulb.
How much electricity does the human brain consume?
I do appreciate your patience.
This would be so much easier if you had a background (even a little) in Electrical Engineering, but I'll try.
I did not say there was no current flow in the Human Brain. I said there was "no significant" current flow.
At any rate, define "significant current flow".
You do understand that there is NO electrical current flow in our brains, Right??!
I understand that an electrical potential, volts, is detected yet electrical activity I took as a change in volts over time. Does this not indicate electric current?
An EEG can only detect and amplify voltage, it cannot "see" current flow.
I don't know if the brain produces electricity but some of the articles I linked claim that it does.
Actually, the brain does not generate electricity. It is called electrical activity, but, it really is more like there are changes in the ion concentrations on the outside and insides of neurons. This allows for electron exchange, but, does not constitute significant current flow.

Your body is capable of generating electricity, and this ability is actually a key part of your achieving health. Electricity allows your nervous system to send signals to your brain. These signals are actually electrical charges that are delivered from cell to cell, allowing for nearly instantaneous communication.
The messages conducted via electrical signals in your body are responsible for controlling the rhythm of your heartbeat, the movement of blood around your body, and much more.
Your biological clock even uses electrical activity in order to help keep your circadian rhythms in order. You are, quite simply, an electrical being. If electrical activity stops in your body, you cannot survive

That's strange. You didn't post this?

I enjoy reading and learning about electromagnetism and, specifically, plasma physics yet I find little time for that as I am not yet retired, working full time, and I have more hobbies than I can shake a stick at. I envy you retired guys. I hope you are collecting a wonderful pension.

Explain to me what constitutes as current flow, which doesn't require electron exchange between atoms.

If you were an actual electrical engineer, and not a guy claiming to be one:
You would never argue that two pieces of Ohm's Law can be present, without the third.
Sorry. You are wrong. You are wrong if you are, or are not an electrical engineer. I don't care about your credentials, you could be Dr. Strange and Tony Starks' genius love child, and you would still be wrong.
"Water pressure (volts) can change without requiring current flow."
No. If an atom "moves" it's nuclei and valence shells move with it.
You can't increase or decrease "pressure" of a water system nor an electrical system without atomic movement.
If an atom moves, it's electrons move.
#1 An electron moves. Current flow.
#2 An atom moves. Still, technically current flow. Electrons in transit act relatively on all others involved.
Pardon me, if your argument relies on local system abstractions and points of reference for measurement. Honestly, that's a straw grasp in the context of this discussion.
If I told you I had a beam that could stop all electron current flow 100% and I could shoot it in a helmet, that you put on your head... Would you gladly put the helmet on and take the beam for 5 minutes?
^ If your answer to that is no, then you see a risk of inherent harm, even though, in your opinion, this device should have zero affect on you.
((Edit: Based on your desire to be "right" and your obvious aversion to admitting a mistake of interpretation, I can already tell this discussion is only going downhill from here. I am pre-emptively putting you on ignore now, I will not discuss these facts against your opinion any longer. If your school's engineering program was allegedly accredited by ABET, you should demand a refund.))

Doesn't even need a decade.
2 years at a community college learning about electronics theory would be enough.
But that requires effort.

The beam of an electron gun. This beam is a measurable amount of current and does not involve the exchange of electrons along a conductor.

What your descibing is a cathode ray and not an electrical current. It isn't a current and I can tell physics means nothing to you. And yes even a cathode ray needs to hit something to exchange electrons.

I once built an electron beam device, although the beam wasn't very well focused. I could use it to charge objects several feet away to a few thousand volts, though that did take several minutes.
Cathode Ray is an old school term for electron beam.

Your also a liar you aren't going to get thousands of volts charge. In fact it's very inefficient. To get thousands you would need hundreds of thousands. Your electric bill would have been thousands though.
Electron beams will always be inefficient because most of the electrons produced dont actual exit the hole. Next magnetic fields effect it so your charging like you claim would cause the beam to distort. Then there's the fact they hold a charge and I'm sure you would have electricuted yourself with thousands of volts. Just the remain in ng charge would take hours to disappear.
