Endocannabinoids reduce marble burying behavior. Mice were injected (i.p.) with the FAAH inhibitor PF-3845, the MAGL inhibitor JZL184, or vehicle and tested in the marble burying assay. Locomotor activity was simultaneously recorded and was quantified as seconds per minute immobile. (A) FAAH dose-dependently reduced marble burying, but (B) had no effect on immobility. (C) JZL184 dose-dependently reduced marble burying, although (D) caused a statistically significant increase in immobility at 40 mg/kg. Data are presented as the mean ± SEM (n = 8). * p < 0.05, ** p < 0.01 vs. vehicle.
