N-methyl-d-aspartate receptor subunit composition in the rat trigeminal principal nucleus remains constant during postnatal development and following neonatal denervation

▶AMPA and NMDA receptors mediate synaptic transmission in the trigeminal brainstem. ▶The ratio of AMPA/NMDA receptor-mediated EPSCs linearly increases postnatally. ▶NMDA receptor subunit composition remains constant during postnatal development. ▶Neonatal denervation does not change these processes.
