“…One important aim of such studies is to causally link specific cognitive processes and behaviors to (changes in) the functioning of specific brain regions and networks in healthy human adults. Notably, extensive review studies have failed to reveal consistent and reproducible effects of tDCS on attentional functions (Reteig, Talsma, van Schouwenburg, & Slagter, ), working memory (Russowsky‐Brunoni & Vanderhasselt, ), or executive function, language, and memory (Horvath, Forte, & Carter, ). rTMS protocols seem to suffer less severely from such issues (e.g., Hsu, Ku, Zanto, & Gazzaley, ), but unexpected or null findings are frequently reported here as well (for review, see, e.g., Guse, Falkai, & Wobrock, ).…”
