Two independent groups in this issue report synaptic communication between callosal axons and the NG2-positive glial precursors in the brain. Activity-dependent vesicular glutamate release from axon collaterals triggers AMPA-type currents in the precursors. This phenomenon might be involved in regulation of oligodendrocyte differentiation or remyelination.
