(a) The differences sucrose intake of rats exposed to establishing CUS model efficacy. *p < .05 were expressed statistically significant, “CUS + Ketamine (N = 10),” “CUS + Vehicle (N = 10),” and “Control (N = 8).” (b) The rapid and long‐term effects of ketamine in this CUS model. (c) The sucrose intake of rats in the study. *p < .05 were expressed between CUS + Ketamine and CUS + Vehicle group statistically significant. ^# p < .05 were expressed between Control and CUS + Vehicle group statistically significant. And the results were group means + standard deviations
