Primary Outcome Measures

Name	Time	Method
On the behavioural level, reaction time, its variability, omission and commission errors will be analysed, detected during a working memory task (n-back-task);<br>Error related negativity and positivity;<br>Power of theta and alpha; <br>On the source level, the harmonic frequency will be analysed using Dynamic Imaging of Coherent Sources. <br>These parameters are recorded for each stimulation condition.<br><br>

Secondary Outcome Measures

Name	Time	Method
Adverse events questionnaire (1).<br>When: After each experimental session.<br><br>(1) C. Poreisz, K. Boros, A. Antal, W. Paulus, Safety aspects of transcranial direct current stimulation concerning healthy subjects and patients, Brain Res Bull, 72 (2007) 208-214<br>
