behavior/neurological
N
• locomotor function, baseline startle response, pain sensitivity and prepulse inhibition are similar to controls
• mice show robust attenuation of freezing when presented with the conditioned stimulus (tone) when tested for expression of previously learned fear
• mice show deficits in short- and long-term learning and memory to the conditioned cue, but display normal rate of extinction of conditioned fear
• 7,8-Dihydroxyflavone treatment rescues this impairment in cued fear conditioning

mortality/aging
• transgenic cre positive animals are obtained with low frequency from crosses with Gt(ROSA)26Sortm1Sor heterozygotes, suggesting that Tg(Cck-cre)CKres carriers may have reduced survival
