Brain regions showing significant intergroup differences in blood oxygen level–dependent (BOLD) signal response to reward (Gain: +$5, No-Gain: $0, Loss: −$5, No-Loss: $0) in individuals with RNT. Shown are the left cerebellar hemisphere (A), midbrain (B), cingulate cortex (C), cerebellar vermis (D), and dorsolateral prefrontal cortex (E). BOLD signals (arbitrary unit) were standardized (mean = 1 and SD = 1). HC, healthy comparison; H-RNT, high repetitive negative thinking; VH-RNT, very high RNT.
