Fig. 2. Enhanced acquisition of contextual, but not cued, fear memory in GluA1C811S mutant mice.

A Freezing ratios in fear conditioning (left) and contextual test (middle) or cued test with altered context (right) 1 day after conditioning. B Shock distances after each shock. C Contextual fear memory at 1, 35, 49, or 125 days after conditioning. D Cured fear memory at 1, 35, 48, or 140 days after conditioning. Bold lines and arrows represent tone and footshock, respectively. All data are expressed as mean ± SEM. The p values indicate genotype effects.
