N normal phenotype
nervous system
N
• mice exhibit normal gross morphology and neuronal density in the hippocampus
• increased excitatory and inhibitory synapse density
• however, thickness and perforation are normal and re-expression of the endogenous gene rescues excitatory synapse numbers
• increased in the density and length of postsynaptic density apposed to presynaptic vesicle
• increased mEPSC frequency but not amplitude
• however, frequency is rescued by re-expression of the endogenous gene
• increased mIPSC frequency but not amplitude
• however, re-expression of the endogenous gene does not rescue mIPSC frequency
