History of migraines 5. implanted defibrillator or implanted neurostimulator 6. pregnant or thought to be pregnant. This must be an exclusion criterion as there are few medical papers available regarding the effects of tDCS on the unborn child/fetus or expectant mother. Thus, if you are pregnant or thought to be pregnant you cannot participate in the study. If you find out you are pregnant in the week timeframe between experiment 1 and experiment 2, you should withdraw from the study as we cannot perform the second experiment in that case. 7. Not done a similar fatigue study in the laboratory in the last 7 days.
