结局指标
主要结局
Performance in a verbal associative learning paradigm under anodal tDCS compared to sham
时间窗: assessed immediately after training period (several learning blocks) compared to sham
Investigation whether anodal tDCS leads to improved performance accuracy in the Wernicko task compared to sham stimulation.
次要结局
- Functional connectivity predictors(assessed during baseline testing)
- Structural predictors(assessed during baseline testing)
- Other cognitive outcome: Attention(assessed directly before and immediately after tDCS + training compared to)
- Genotyping of learning related polymorphisms(: assessed during baseline screening)
- Other cognitive outcome: Working memory(assessed directly before and immediately after tDCS + training compared to)
