OBJECTIVE To verify a behavioral device for the detection of learning, memory, and affective disorders in post-weaning socially isolated rats. METHODS We tested the behavioral changes in post-weaning socially isolated rats using a multi-function closed maze, a self-developed behavioral device, against the classical mood disorder detection method, the IntelliCage system and Morris water maze. RESULTS In the multifunctional closed maze experiment, the spatial learning and memory ability of post-weaning socially isolated rats decreased, which was consistent with the results of the water maze and IntelliCage system. Furthermore, the behavioral changes in the post-weaning socially isolated rats in the multi-function closed maze test were the same as those of the forced swimming and open field tests, indicating that the rats had depression- and anxiety-like behaviors. CONCLUSION A multi-function closed maze can detect emotional changes, spatial learning ability, and memory ability.
