Figure 3. Variations in Stimulus Pup USVs and Relationship with Maternal Preference-Like behavior.

Figure 3

On PPD 1, CC stimulus pups (A) emitted fewer USVs with (B) a greater interval between USVs. On PPD 1, the amount of time CC dams spent on a pup side (not engaged in touch/sniff behavior) was positively associated with (C) total number of USVs pups emitted. * p<0.05, *** p<0.005
