tACS stimulation phase changes detection but not overall performance versus sham.

Evidence

Figure 2b shows performance averaged across phase conditions to facilitate comparison of the hypothesized positive half-cycle (30, 150°) with the opposite half-cycle (210, 270, 330°) and baseline. Paired t-tests revealed an effect of half-cycle polarity on performance (positive vs. negative half-cycle: t(13) = 2.48, corrected p = 0.042); thus tACS phase modulated click detection. Comparison with baseline revealed no effect. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4804
