N normal phenotype
behavior/neurological
• mice exhibit deficits in contextual fear conditioning
• mice exhibit reduced freezing levels in 24 hour fear memory test, however, conditioning to tone is normal in an amygdala-dependent cued-fear conditioning protocol

nervous system
• impaired late phase long term potentiation (L-LTP) at the medial perforant path-dentate gyrus synapse
• mice exhibit a reduced fEPSP (excitatory postsynaptic potential) slope following a theta burst used to induce L-LTP as compared to controls
