Tonically active NMDA receptors – a signalling mechanism critical for interneuronal excitability in the CA 1 stratum radiatum

In contrast to tonic extrasynaptic γ‐aminobutyric acid ( GABA ) A receptor‐mediated signalling, the physiological significance of tonic extrasynaptic N ‐methyl‐ d ‐aspartate ( NMDA ) receptor ( NMDAR )‐mediated signalling remains uncertain. In this study, reversible open‐channel blockers of NMDAR…
