Figure 2
Mean concentrations (ng/g) of A) Serotonin (5-HT), B) 5-HIAA and C) the 5-HIAA/5-HT ratio in brain stem of omission of expected reward (OER) and control groups under unstressed and stressed conditions.
ANOVA statistics, A: F(3) = 1.07, p = 0.37, B: F(3) = 27.45, p<0.001, C: F(3) = 17.89, P<0.001. Tukey HSD post-hoc significance levels are indicated by differing letters when p<0.05.
