Parametric fMRI analysis. (a) State-action value signals were encoded in intraparietal sulcus (IPS: (−21 −36 60), k = 394, FWE corr. p < 0.05), right ventral striatum (rVS: (9 12 −9), k = 61, SVC p < 0.05)13, and ventro-medial prefrontal cortex (vmPFC: (0 33 −9), k = 38, SVC p < 0.05)1. (b) Reward prediction error signals were encoded in left and right putamen (rPutamen: (27 −15 9), k = 58, SVC p < 0.05; lPutamen: (−21 9 9), k = 74, SVC p < 0.05)11. (c) Cognitive entropy signals were encoded in frontopolar cortex (FPC: (12 60 3), k = 20, SVC p < 0.05)15. FWE: whole-brain familywise error correction. SVC: small volume correction, equal threshold with p < 0.05 and k > 10 voxels of correction within 10 mm sphere centred by known peak-coordinate was applied.
