..g., verbal fluency measures and left prefrontal cortex, PÂ =Â 0.035). The results indicate that single-session tDCS produces significant and reliable effects on language measures in healthy adults. ..

..Notably, accuracy or errors were not influenced by SMG stimulation compared to vertex. In line with our predictions, the findings provide compelling evidence for right STG's involvement in healthy stimulus-centered spatial processing. ..
