A rapid change in the membrane potential of excitable cells such as neurons and muscles; this usually involves a steep rise (depolarization) followed by a steep fall in membrane potential (repolarization). The cell subsequently enters a short refractory period (hyperpolarized state) during which it cannot generate another action potential.

Why does increasing the space constant increase conduction velocity in myelinated neurons if...
I think the simplest answer to your question is that you're correct in thinking passive flow would be what changes, but the reason behind it is important to understand.
I'd recommend looking at UT Hea …

What makes synaptic vesicle release probabilistic?
From the source you provided, the answers seem to be outlined well from the authors' sentence that states:
The Pr [release probability] of SVs [synaptic vesicles] at the AZ [active zone] is set by …

Inward rectifying potassium channels during undershoot of action potential
I hope I can maybe shed some light on this concept for you. Rather than complicate anything more than necessary, let's start small and build. To directly answer your question, these channels can func …
