The animals were divided into 2 groups. One group was treated with FLX pellets (Innovative Research of America, Sarasota, FL) for 4 weeks at a dose of 3 mg/kg/day, whereas the other group was treated with control pellets (Innovative Research of America) for the same period. This dosage was chosen based on results of a previous study showing behavioral alterations in marmosets receiving the same dose [14 (link)]. Animals were anesthetized with an intramuscular injection of ketamine hydrochloride (50–60 mg/kg) and medetomidine hydrochloride (0.1–0.15 mg/kg), followed by atipamezole hydrochloride injection of 0.5–0.75 mg/kg. FLX or control pellets were implanted subcutaneously on their backs [15 (link)].
