Systemic injection of Ro25-6981 abolished the impairment of long-term memory retrieval caused by acute stress. (A) Summary of the time spent in the test (Q_test) and opposite quadrants (Q_opp) for rats in the control (n = 20), stress (n = 21), and stress + Ro25-6981 groups (n = 16). *, Significant within-group difference between time spent in the Q_test and Q_opp (P < 0.05); #, significant between-group difference in time spent in the Q_test (P < 0.05) when the stress group is compared with either of the other groups. (B) Representative swim paths of rats in the control and stress groups during the probe test.
