Anna Krasnow, a PhD student on the Wellcome Trust Neuroscience program, has just published her study on myelination in Nature Neuroscience. Anna, who is predominently based in David Attwell's lab at UCL, collaborated with Leo Valdivia in Steve Wilson's group on this work. The resulting paper looks at the role that calcium transients in oligodendrocytes have on the developing myelin sheath. Anna found that neuronal activity raises calcium levels in developing oligodendrocytes and that myelin sheath elongation is promoted by high frequency calcium transients.
Congratulations Anna et al on a beautiful study!
