Figure 2

The effects of lithium and VPA on sexual, grooming, rearing, and feeding behaviors. This figure shows that lithium, but not VPA, significantly attenuated the frequency of (A) sexual behavior (*P = 0.024) and (B) the duration of grooming behavior (*P = 0.027). Both lithium and VPA reduced the frequency of rearing behavior [*P < 0.0001] (C), but neither lithium nor VPA had an effect on the frequency of feeding behavior (*P = 0.065) (D) by two-way ANOVA; *P < 0.05 by post hoc test; n = 10 to 12 per group. Data is expressed as mean ± SEM.
