The behavioral changes in open-field and sucrose consumption test. Rats in both the depression and post-MI (myocardial infarction) depression groups showed significantly lower scores of both horizontal and vertical movement compared with the sham and MI groups (^a P < 0.01) (A). The total consumptions of sucrose was significantly lower in the depression and post-MI depression groups compared to the sham and MI groups after the experiment (^a P < 0.01, ^b P < 0.05) (B).
