Saltatory conduction — the process by which action potentials propagate along myelinated nerves — depends on the fact that voltage-gated Na + channels form clusters at the nodes of Ranvier, between ...

Using newly developed markers, the scientists were able to visualize axons, myelin, and nodes of Ranvier in vivo. A version of this image is used in the current article in Current Biology, DOI: ...

Researchers have achieved patch-clamp studies of an elusive part of mammalian myelinated nerves called the Nodes of Ranvier. At the nodes, they found unexpected potassium channels that give the ...
