Figure 6. PAR1−/− male mice show significant deficits in fear-conditioned freezing.

Figure 6.

(A) Wild-type and PAR1−/− mice (n=6 per genotype) showed similar baseline startle and prepulse inhibition responses (n=6 per genotype; p>0.05 for each prepulse stimulus, unpaired t-test). (B), Wild-type and PAR1−/− mice also acquired similar freezing responses by the end of training. (C) When tested 1 day after training, PAR1−/− mice displayed significantly reduced freezing compared to wild-type mice (p=0.02; unpaired t-test; WT n=11, PAR1−/− n=12). Data are presented as mean ± SEM.
