In this issue, Papouin et al. show that glycine is the endogenous coagonist for extrasynaptic NMDA receptors (NMDARs), unlike at synapses where the coagonist is d-serine. By enzymatically degrading endogenous glycine, they begin to address the enigmatic physiological and pathological roles for extrasynaptic NMDARs.
