nervous system
decreased excitatory postsynaptic current amplitude ( J:193625 )
• very small or no NMDAR excitatory postsynaptic currents at P10 and P13 to P14 in some ventral posteromedial nucleus neurons
• however, EPSCs from principal trigeminal nucleus are normal
abnormal NMDA-mediated synaptic currents ( J:193625 )
• at P13 to P14, deletion of NMDARs disrupts elimination of redundant inputs, synaptic strengthening and pruning of somatic innervation compared to in wild-type mice
• however, EPSCs from principal trigeminal nucleus are normal
reduced NMDA-mediated synaptic currents ( J:193625 )
• very small or no NMDAR excitatory postsynaptic currents at P10 and P13 to P14 in some ventral posteromedial nucleus neurons
abnormal miniature excitatory postsynaptic currents ( J:193625 )
• reduced frequency, amplitude and decay constant in the absence of NMDAR at P13
