Preserved oligodendrocytes (IMAGE) Picower Institute at MIT Caption To assess the number of immature and mature oligodendrocytes in the corpus callosum in mice fed cuprizone and given 40 Hz stimulation (right), compared to mice fed cuprizone and given constant stimulation as a control, researchers measured the marker PDGFRa (green) and APCCC1 (red). The 40Hz group exhibited a signficantly higher number of each type of oligodendrocytes.
