Experimental design and task procedure. (a) Design of the experiment. The “part” states each experimental phase. The horizontal dark blue arrow shows the time-course and application order of the parts with durations of them in minutes. The vertical grey arrows show the application order of the numbered measurements stated in the part. (b) The representations of the applied visual* (on the left) and auditory (on the right) memory tasks during the EEG recordings. * Given schematic images in Fig. 4b are not actual exemplars from the Boston naming test set; drawn by TA as an example. tACS, transcranial alternating current stimulation; ITF, individual theta frequency; min, minute; sec., second.
