Study design. (a) General experimental design with four main time points and requirements that subjects had to meet to complete the whole study. SCR refers to screening. L-DLPFC vs VERTEX DROP ≥ 1 SD* refers to a reduction of at least 1 standard deviation (12.5%) in the Recognition performance during L-DLPFC stimulation condition compared to that during vertex stimulation condition. (b) Memory task performed on each experimental day (day 1, day 2 and day 3). MTH refers to motor threshold estimation. Drug test consisted of taking a urine sample and a breath test.
