Figure 2. Effects of NPS in the LA/BLA during retrieval and extinction of conditioned fear.

Figure 2

Averages of relative freezing duration upon CS+ presentation during retrieval sessions (R1–R6), extinction (E1, E1), and renewal (RN). Diagrams represent effect of bilateral injections into LA/BLA of (A) NPS and NaCl 20 minutes before training, and (B) NPS, SHA 68 and NaCl two hours before retrieval session 1. Data are mean ± S.E.M. Asterisks indicate differences in freezing in a respective session after administration of NPS or SHA 68 compared to saline (*, p < 0.05; **, p < 0.01).
