Figure 3. Lactating TPH2−/− dams do not show increased aggression to male intruders in the presence of their own or cross-fostered TPH2+/+ pups.

Figure 3

Aggressive behavior shown by lactating TPH2+/+ (WT) or TPH2−/− (KO) dams in the presence of the indicated litters was compared to that of non-lactating WT and KO (Ctrl WT or Ctrl KO) females upon the introduction into their cages of a socialized male intruder. Dam and litter genotypes are designated as described in the legend of Fig. 1. Aggressive behaviors were scored as (a) number of attacks on the intruder and (b) latency to attack the intruder. Data are expressed as the mean ± SEM. *P < 0.05, **P < 0.001.
