(A) Source reconstruction of MEG data in the beta band (12–32 Hz, 100–373 ms after STOP/AC-GO [attentional capture go] signal onset). Surface plots show t-values of significant clusters when contrasting successful stop (sSTOP) and correct attentional capture go (cAC-GO) trials (cluster-based permutation test, two-tailed, cluster = 0.05, n = 59). Peak voxels (local extrema) of these clusters are highlighted and labeled (MNI coordinates are shown in Table 1). Dashed circles indicate that the peak voxel is not directly visible on the surface. Anatomical regions: rIFG, right inferior frontal gyrus, pre-SMA, pre-supplementary motor area, l-IFG, left inferior frontal gyrus, lAIns, left anterior insula, lMFG, left middle frontal gyrus, lPMC, left premotor cortex, rPMC, right premotor cortex. (B) fMRI activation maps for the contrast sSTOP versus cAC-GO; map thresholded pFWE < 0.05, cluster extent k = 5 voxels, n = 76. Positive activation, that is, positive -values (red color), is obtained by the contrast sSTOP > cAC-GO, while negative activation, that is, negative -values (blue color), is obtained by the contrast sSTOP < cAC-GO. Data are taken from Sebastian et al., 2017. (C) Overlap between MEG (A) and fMRI (B) activity. To compare the activity revealed by both methods, the product of normalized -values from both methods is displayed. Peak voxels of right inferior frontal gyrus (rIFG) and pre-supplementary motor area (pre-SMA) as found in the MEG analysis are highlighted and labeled.
