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: ...
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: ...
