Fatty myelin covers nerves' axons ensuring electrical signals pass along to their destination rapidly and effectively. This study in zebrafish, mice and human tissue reveals how the cells producing and wrapping the myelin – the oligodendrocytes – myelinate complex circuits by each proceeding at different rates making a flexible chain of myelin sheaths connected by cytoplasm (here the process is underway in a still from an electron microscopy reconstruction)

What is BPoD?
BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
