Figure 3. Behavioral abnormalities in Gabrd^+/− and Gabrd^−/− mice postpartum.

a, Gabrd^−/− mice exhibit a decreased latency to immobility and an increase in the total time immobile during a 6 min Porsolt forced swim test. b, Over a 48 hour period, virgin wild type, postpartum wild type, and virgin Gabrd^−/− mice consumed more 2% sucrose solution than water in the sucrose preference test. Postpartum Gabrd^−/− mice did not prefer the 2% sucrose solution. c, Virgin and postpartum wild type and Gabrd^−/− mice had a similar latency to attack in the resident-intruder assay. Gabrd^−/− mice exhibited more anxious behaviors postpartum in response to the intruder when compared to virgin or postpartum wild type mice.
