All coordinates are presented in the Montreal Neurological Institute template space. Anatomical labels were identified using the SPM Anatomy Toolbox. Results were obtained through generalized psycho-physiological interaction (gPPI) analysis (minimum voxel extent of 20 voxels and p < 0.001 significance threshold, uncorrected).
