چکیده انگلیسی
Female rats alternately approach and avoid the male rat during copulation, potentially reflecting appetitive and aversive aspects of mating, respectively. We developed a novel classical conditioning procedure, conditioned object preference (COP), to test whether female rats show increased approach toward a conditioned stimulus associated directly with receipt of sexual stimulation. During conditioning, one scented object was paired with an appetitive stimulus and a different object plus scent was paired with a control stimulus on a separate day. After conditioning, preference for each object was evaluated with a choice task. Experiment 1 was conducted to verify the procedure. Rats exhibited a significant COP for 1 mg/kg amphetamine, indicating that the conditioned object preference procedure is an effective tool for evaluating the rewarding nature of a treatment. In Experiment 2, paced mating to one ejaculation and experimenter-delivered artificial vaginocervical stimulation (aVCS) each induced a COP. The robust COPs for paced mating and aVCS support the notion that female rats experience a reward state during receipt of sexual stimulation. Moreover, the data suggest that any aversive aspects of receipt of sexual stimulation do not overshadow the appetitive effects.
