Noninvasive transcranial brain stimulation has been widely used in experimental and clinical applications to perturb the brain activity, aiming at promoting synaptic plasticity or enhancing functional connectivity within targeted brain regions. However, there are different types of neurostimulations and various choices of stimulation parameters; ho...

... seen in Table I, there were three tDCS trials during nap time, one with 5-min stimulation duration, and the other two with 30-s duration. In these three trials, we found the most consistent and significantly decreased conditional GC between clusters 6 → 1 and 5 → 2, especially at low frequencies (Fig. 3). In single trial analyses, the significance threshold was empirically set by the mean±2 SD among all GC values within that trial. In contrast, we found a significant conditional GC increase in 2 → 5 and 1 → 6. Among three frequency bands, the increased or decreased GC trend was greatest in the delta band, followed by theta and alpha ...
