Long-term impairment of contextual fear memory in CLP-exposed mice. Male C57BL/6 mice are subjected to the associative fear conditioning paradigm at different post-surgical time points, and the results are grouped into three intervals. The CLP group shows impairment in the contextual test when compared with the sham group at each time point (*P < 0.05; ** P < 0.01 by t test).
