Effect of reproductive experience on the percentage of oxytocin neurons in the PVN and SON and dopamine or kisspeptin neurons in the ARC that colocalized with pSTAT5 immunoreactivity in response to graded doses of prolactin (2.5, 100, or 4000 ng/rat icv) or vehicle (n = 6–8 per group). Each dose was delivered in separate vehicle-controlled experiments; results from all vehicle-treated rats are pooled into groups of 12–14 for presentation. **, P < 0.001 vs. corresponding vehicle controls.
