Fig. 2. Massive Extinction before Reconditioning Prevents Rapid Reacquisition of Contextual Fear Conditioning.

Fig. 2.

(A) Overview of the design of Experiment 1b. The times listed represent the total time of exposure to the context for a given session. A plus sign indicates a single .35 mA shock and a minus sign indicates exposure to the context without shock. (B) Freezing during each extinction session (E) by mice that received fear conditioning (RECOND) or context exposure (CTX) on Day 1 (Day 2-15). (C) Mean freezing from Test (1 day after reconditioning) for each group. Significance between groups is represented by *** p < .001; ** p < .01; * p < .05. RECOND, n= 8; CTX, n=8; COND, n=8. Error bars represent standard error of the mean.
