Global network properties of functional connectivity in the fear-related and sensory-motor-related regions. Significant interactions between Stimulation (Pre-stim, Post-stim) × Dosage (Low-dose, High-dose) of the global network properties were observed in (A) the fear-related regions, not in (B) the sensory-motor-related regions. In the fear-related regions, global node degree, global node strength, and global efficiency were increased in the high-dose condition but not in the low-dose condition after electrical stimulation. However, in the sensory-motor-related regions, there were no significant increases after electrical stimulation in both high- and low-dose conditions.
