Several studies have evaluated the effect of anodal transcranial direct current stimulation
(tDCS) over the prefrontal cortex (PFC) for the enhancement of working memory (WM)
performance in healthy older adults. However, the mixed results obtained so far suggest the
need for concurrent brain imaging, in order to more directly examine tDCS effects. The
present study adopted a continuous multimodal approach utilizing functional near-infrared
spectroscopy (fNIRS) to examine the interactive effects of tDCS combined with …
