Design outcomes
Primary
| Measure | Time frame |
|---|---|
| On the behavioural level, reaction time, its variability, omission and commission errors will be analysed, detected during a working memory task ("n-back"-task); Error related negativity and positivity; Power of theta and alpha; On the source level, the harmonic frequency will be analysed using Dynamic Imaging of Coherent Sources. These parameters are recorded for each stimulation condition. | — |
Secondary
| Measure | Time frame |
|---|---|
| Adverse events questionnaire (1). When: After each experimental session. (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 | — |
