研究概览
简要总结
The aim of this study is to investigate whether a combination of intensive training of visual-spatial abilities (LOCATO task) with anodal transcranial direct current stimulation (tDCS) leads to an improvement of learning and memory in healthy young adults and to examine the underlying neuronal mechanism.
