From synapse to sheath: how OPCs couple neural activity to adaptive myelination and behavioral plasticity
Oligodendrocyte precursor cells (OPCs) are abundant progenitor cells in the central nervous system. Unlike mature oligodendrocytes, OPCs form functional synapses with neurons and respond to both glutamatergic and GABAergic signals. Glutamate activates calcium-permeable AMPA receptors on OPCs, generating local Ca 2+...
