Main effects of regional lfSSBRs. At the fundamental frequency, significant lfSSBRs were evoked in the visual, sensorimotor, ventral attention, salience, and central executive networks (A). At the first harmonic, remarkable lfSSBRs were shown only in the visual and sensorimotor networks (B). All results were corrected with FWE method (P < 0.05) and visualized with the BrainNet Viewer [Xia et al., 2013].
