Sertraline (Pfizer Inc, CT, USA) was administered at a dose of 25 mg/kg i.p. 30 min prior to the forced-swim test. The FST was conducted as previously described [3 (link)]. Each session lasted for 300 s and was videorecorded. Unbiased analysis of total immobility time over the final 240 s was performed using the ForcedSwimScan (CleverSys Inc, VA, USA).
