Schematic timeline of this research. Pregnant rats received 2-h exposure of 3.5% sevoflurane or air in the day 0 of gestation (G0). Thirty min prior to sevoflurane or air exposure, rats were subjected to intraperitoneal injection with Rimonabant (RIM, 1 mg/kg) or vehicle (Veh). Brain tissues were harvested from fetal rats at 6, 12, or 24 h subsequent to sevoflurane exposure. The offspring rats in each group were employed for neurobehavioral tests and Morris water maze (MWM) tests during P3–33. Next, the hippocampus was harvested 1 h after MWM test.
