Textbook models say an oligodendrocyte wraps an axon steadily and symmetrically. By following individual sheaths as they formed, we found that wrapping is asynchronous — leaving partially wrapped zones that let a single cell reach past a branch point and link neighboring sheaths by thin cytoplasmic bridges. This lets one cell myelinate more of a circuit than thought possible, but leaves the resulting chains vulnerable to degeneration with age.

Cortical neurons exhibit diverse myelination patterns that scale between mouse brain regions and regenerate after demyelination

Call CL, Bergles DE

Nature Communications · 12, 4767 · 2021

The cortex doesn't myelinate every axon the same way. We mapped myelination across cortical neuron types and found a clear hierarchy of preferences — then showed that after demyelination, regeneration reshapes those patterns rather than faithfully restoring them, raising new questions about what the patterns are for.
