Figure 1From: Inducible nitric oxide synthase is involved in the modulation of depressive behaviors induced by unpredictable chronic mild stress Unpredictable chronic mild stress (UCMS) induced the decrease of sucrose preference in a time-dependent manner. UCMS-exposed mice were subjected to UCMS for 4 weeks. Sucrose preference was evaluated via sucrose uptake rate, namely, ratio of volume of sucrose consumption to volume of sucrose plus tap water consumption. Data are mean ± SEM (n = 7 for control; n = 6 for stress).Back to article page
