The Action Potential in the Note of Ranvier

It's really hard to isolate single mammalian nerve fibers. The invention of the patch clamp recording is a very good method for studying channel and electrical properties of cells, but not for the note of Ranvier. These are these little segments of a neuron that allows... They're the little gaps in the gaps in the myelin and myelinated. And they allow for a fast conductance of things like that long distance.
