I agree, and you still get it wrong.
Apparently you can't comprehend what you read because they clearly state the flow of current in the opening paragraph and explain how it works in the rest of the video.
You here one word, current, and then your ears and eyes close. Please, try and learn something.
Apparently you seem to think that electrical energy in plasma typically travels in straight lines or something. I don't see any evidence that you learned anything from that video, and I see direct evidence that you closed your eyes (pure denial) to the information it contained. It clearly spoke in terms of the flow of current, and you completely ignored it, apparently because you think electrical energy in plasma must necessarily travel in a straight line? Even in a Birkeland current, current doesn't travel in straight lines.
If the nerve impulse was a current it would be along the body of the axon in the direction of the nerve impulse.
So what? That's utterly irrelevant! Current in space *rarely* travels in a straight line. It forms Birkeland currents that create those "
magnetic slinky" patterns (aka
Birkeland currents) in space!
It isn't. Instead, the ion flux is at a right angle to the nerve impulse. Therefore, the nerve impulse can not be a current.
Utterly false. You *assume* that current travels in a straight line. It doesn't do that in plasma and it doesn't do that in brain cells either!
You can't even understand the basics of neurophysiology. Don't blame McGraw-Hill for that.
I don't blame McGraw-Hill for anything. They explained those *currents* quite clearly! Too bad you can't comprehend what you watch.
That's laughable. It is entirely relevant. The charged particles do not move down the neuron as a current as you claim.
Who claimed current ran in straight lines in spacetime? It sure a heck wasn't me! Why would I even *expect*, let alone *require* the brain to carry current in "straight lines"?
Your entire argument is based upon your own strawman argument, specifically that "current" must necessarily run along a straight path. Nobody claims that but you and only you.
Every single reference agrees with me. You need to do more than a word search for current.
The problem is that when I do a word search, "current", "voltage" and charged particles all appear in them. You're just in denial that the term "current" appears in every single one of them!
