ENP doctoral student Paloma Maldonado recently advanced our understanding of oligodendrocyte precursor cells in grey matter. She revealed that these cells detect slight changes in extracellular potassium levels resulting from neuronal activation. This finding suggests that oligodendrocyte precursor cells in the adult have an alternative function to serving as progenitors. Check out the article for more details:
