R posterior IFG (pars opercularis)	50 8 20	Area 44	4.5
R/L cerebellum (vermis)	2 −56 −22	Lobule V	5.7
R temporoparietal junction (STG)	60 −40 10	-	1.9

Note. Coordinates x, y, z of the cluster’s peak voxel refer to Montreal Neurological Institute (MNI) space; histological assignments refer to (parts of) the cluster (and not necessarily the peak voxel).

VA = vigilant attention; L = left; R = right; BA = Brodmann area; pre−SMA = pre−supplementary motor area; MFG/IFG = superior/middle/inferior frontal gyrus; vPMC = ventral premotor cortex; IPS: intraparietal sulcus; STG = superior temporal gyrus.
