Perfusion results. A CBF increase after tACS. Paired t test (post>pre, p<0.05, FDR-corrected) revealed an increase of CBF selectively involving the right temporal lobe, representing the common site of stimulation across participants (n = 15). B Whole cortical brain CBF analyses of participants who received the highest dose of tACS (20h of bilateral temporal lobe stimulation over 4 weeks, n = 5, Group 3) revealed a selective increase in CBF in the bilateral temporal lobes, accordingly to the stimulation template (p<0.05, FDR-corrected). C Examples of CBF variations in two representative participants belonging to Group 2 (pt #8) and 3 (pt #14)
