Experimental setup to examine lPB-CeC and BLA-CeC EPSCs following fear learning. A, Experimental schedules for the five different mice groups. FC, fear conditioning; CS, conditioned stimulus; US, unconditioned stimulus. B, Freezing time ratio during retrieval. The first points represent the freezing ratio during the 2-min baseline period in the chamber, while the 2nd to 5th points corresponds to 1–30 s, 31–60 s, 61–90 s and 91–120 s after the onset of the CS presentation. C, Recording configuration for lPB-CeC and BLA-CeC EPSCs. D, Oblique illumination optical images showing electrode placement (tip of a recording electrode indicated with an arrowhead) and CeC cells (bottom). Scale bars are 100 μm (top) and 10 μm (bottom).
