Huh? Relevance? This has nothing to do with the biophysics of action potentials.

  "neuroscientists" and the like go deep in the weeds with what/how different chemicals interact with cells, neurons, etc; but in general i don't read a lot of papers that try to answer "why". Scientists studied automobiles and discovered that applying pressure to a lever in the car causes the motion of the car to slow and possibly stop. End of paper, we proved cars stopped when we put pressure on a lever. No mention of friction anywhere. I've been balking about this since at least 2006-2007 online and in person, and it took about a decade for studies that showed "why", not just "how/what". Then again, most people don't know that our bodies have dedicated receptors for nicotinoids, cannibinoids, opioids. Most people also don't know that tomato ketchup has nicotine in it, or that nearly all grasses contain the precursors to opioids in them. Once your intestines get a substance, nearly all bets are off as to what comes out, at what rate, and what volume. So, essentially, that neuroscientists disagree isn't novel. They're laser focused on the post hoc, rather than the cause(s).
