Intra-VTA PTX treatment stimulates maternal behavior. Adult, virgin female rats were infused bilaterally into the VTA with PTX (0.1 or 0.3 μg/hemisphere) or its inactive control. Groups of 9–11 animals were tested for maternal responding to donor pups beginning on post-treatment day 4. Panel A: Data are cumulative percentage displaying FMB. Fisher’s Exact Tests – *P<0.05 vs. Control. Panel B: Data are median latency to FMB. Percentiles (95th and 25th) are represented by the upper and lower horizontal lines, respectively. Kruskal-Wallis One-Way ANOVA on Ranks – H= (2)9.130, P = 0.010. †P<0.05 vs. Control.
