Figure 4. Administration of CyPPA normalizes fear memory.

Figure 4

A) Freezing during acquisition of fear conditioning on the first day was not significantly different in those rats that were to be tested for the effectiveness of CyPPA (5 mg/kg) on fear memory during the second day. B) During habituation on the testing day, there is no significant effect of repeated restraint stress on freezing when CyPPA is administered. C) During testing of memory of conditioned fear there is no significant effect of repeated restraint stress on freezing to the conditioned tone if CyPPA is administered (5 mg/kg), in contrast to vehicle conditions (Fig 2).
