Percentage of time spent freezing in the shock context during fear recall testing 28 d after shock or 60 s after receiving a shock. Nonshocked (control) and shocked WT and PTH2R-KO mice were from postshock and postrecall groups used for the evaluation of c-Fos expression.
↵*p < 0.05 versus shocked WT at the same time point. N/A, not available.
