Cue phase functional MRI results displayed at an uncorrected P = 0.001 and 48-voxel cluster extent (cluster-level alpha of 0.05). Because cluster-extent based thresholding was used for multiple comparisons correction, voxels are displayed using a binary threshold. For further rationale about using binary maps in the context of cluster-based thresholding, see Woo et al, (2014). Increased responses were observed during processing of reward (vs no-reward) cue in subcortical regions and fronto-parietal regions. MPFC: medial prefrontal cortex, MFG: middle frontal gyrus, Ant. Ins: anterior insula, Thal: Thalamus, MB: midbrain, FEF: frontal eye-fields, IPS: intraparietal sulcus.
