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 ...

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 ...

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: ...

3D reconstruction of electron microscopy images showing a perinodal astrocyte (blue), node of Ranvier (gray), compact myelin (purple), and layers of myelin detaching from the axon (tan). Disclaimer: ...
