Figure 4. Maternal experience-dependent changes in behavior.

Figure 4.

A second independent group of TRAP2;Ai14 virgin female mice (N=9) were used to investigate experience-induced alterations in maternal circuit activation. Experienced-induced changes in multiple aspects of behavior were quantified on each test day following foster pup presentation. Nearly all TRAP2;Ai14 mice retrieved pups on each test day (A). Repeated maternal experience reduced the latency to initiate and complete pup retrieval in TRAP2;Ai14 virgin mice (B-C). Repeated experience also increased time spent in nursing postures and sniffing/licking behavior (D-E), but had no effect on the nestbuilding (F) or total time spent in tactile contact with pups (G). *Day 1 versus Day 6, p< 0.05; **Day 1 vs Day 6, p<0.005; ***Day1 vs Day 6, p<0.0001
