a The reversal-related significantly enhanced neural signals in MD, dmPFC and CN (Switch > Steady State, one-sided paired t-test, p < 0.05, whole-brain family-wise error (FWE)-corrected). T-maps are displayed at p < 0.001, uncorrected, for display purposes only. b Modulation of connections by rule reversals. Bayesian model selection revealed that rule reversals significantly modulated the recurrent connectivity between MD and dmPFC and between MD and CN. c The significant correlation between the modulatory effect on the connectivity from the dmPFC to the MD (Spearman correlation: r = −0.484, p = 0.018) suggests that a slower transition is linked to a stronger modulatory influence on dmPFC-to-MD connectivity. The gray shaded area indicates a 95% confidence level. MD-mediodorsal thalamus, dmPFC-dorsomedial prefrontal cortex, and CN-caudate nucleus.
