(A) Schematic of experimental design. Rat dams (PP4-6, n=10, PP19-21, n=12) were first exposed with their own pups (ex. PP4-6 pups), reconditioned, and then re-exposed to the threat in the presence of age mismatched pups (PP19-21 pups). (B) Box plots show time PP4-6 dams spent (after 1 st odor) behaving towards the threat (left) or pups (right) when in the presence of their own (matched, PP4-6 pups) and in the presence of PP19-21 pups (mismatched). (C) Same as in B for PP19-21 dams. ** denotes p<0.01.
