I stand on what I've posted. So do you. So does Neuroscience.

If such 'rasnkels', then the best thing to do is get me an
opportunity to go, in-person, before the 'inquisition'.

"Still it moves."

know

between it

|
| The normal level of stimulation. The level at which is would normal
fire
| an AP at. The threshold of activation. Call it whatever you want,
if you
| want to argue that there is no such thing, you're going against
what
| everybody bar you thinks.

|
| I don't think the poster was interesting in comprehending the
nervous
| system as a whole. He wanted to know how far a AP travel during the
| absolute refractory period, so I told him.
