Amyloid-β plaque burden and conditioned fear memory in CRND8 mice. (A) The levels of amyloid-β burden (mean (%) ± SEM) significantly increased in CRND8 mice between the ages of three and 12 months. The progressing with age Aβ plaque burden was significantly associated with deterioration in (B) contextual (P < 0.05) and in (C) tone (P < 0.05) fear memory in CRND8 mice. ** P < 0.01, *** P < 0.001.
