Retrieval of trace fear acquired under ReRh inactivation reprised under ReRh inactivation. A, Experimental design. Animals underwent a 2-d behavioral experiment, in which the animals received drug infusion immediately before both conditioning and retrieval test. B, Injector tip placements of all the animals included in data analyses at levels −1.92, −2.16, −2.52, and −3.00 mm posterior relative to bregma. The gray areas marked in the atlas are the Re and ventral Re. C, The freezing behavior of SAL-SAL (n = 10), MUS-SAL (n = 9), and MUS-MUS groups (n = 9) when the injections were performed before both conditioning and retrieval test.
