Timeline of the experiment. Before the experiment, the animals were allowed a 7-days adaptation period. The rats in the surgery groups underwent lateral ventricular catheterization and were allowed to recover for one week. Except for the control group, the rats in the other groups were subjected to CUMS for 6 weeks and treated with different drugs from the fourth week to the sixth week. The body weights and food intake levels were monitored weekly. A SPT was performed on day 0 (baseline SP test), day 21 and day 41. The OFT and FST were performed in week 6. Then, the rats were sacrificed for further detection.
