Sucrose consumption test.

<p>The rats were presented with a sucrose solution (1.5%) for one hour after 14 hours of food and water deprivation in order to evaluate their hedonic state during the CMS procedure (8 weeks). The studied animals showed a significant decrease of sucrose consumption in the anhedonic-like group, whereas the resilient animals showed no change compared with the control animals. The analysis was performed with two-way ANOVA for repeated measures. The data are presented as mean±SD. *p<.001. The figure was adapted from Delgado y Palacios <i>et al.</i> <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0095077#pone.0095077-DelgadoyPalacios1" target="_blank">[18]</a>.
