nervous system

nervous system phenotype ( J:191219 )

N • mice exhibit no gross abnormalities in brain structure and anatomy, neuronal organization and basal synaptic transmission

abnormal synaptic plasticity ( J:191219 )

abnormal excitatory postsynaptic potential ( J:191219 )

• following 10 Hz or 1 Hz low-frequency stimulation, sections fail to exhibit an initial decrease in field excitatory postsynaptic potential (sEPSP) slope compared with sections from wild-type mice

• following 1 Hz paired pulse low-frequency stimulation, slices exhibit less of a decrease in sEPSP slope compared with slices from wild-type mice

• fEPSPs fail to return to pre-long term potentiation baseline after low frequency stimulation as in slices from wild-type mice

abnormal AMPA-mediated synaptic currents ( J:191219 )

• basal synaptic activity of Gria2-lacking AMPA receptors is increased compared to in wild-type mice

enhanced long-term potentiation ( J:191219 )

• following 1 x 100 Hz, 1 s high frequency stimulation NMDAR-dependent long term potentiation is enhanced compared to in slices from wild-type mice

• however, no difference is observed with 50 Hz, 2 s stimulation

absent long-term depression ( J:191219 )

• following 1 Hz low-frequency stimulation

• however, there is no significant LTP or LTD relative to baseline following 10 Hz stimulation

reduced long-term depression ( J:191219 )

• following 1 Hz paired pulse with a 50 ms interpulse interval
