Influence of tDCS of the right DLPFC on verbal working memory and non-noxious and noxious thermal stimulation

Objective: Experimentally induced pain can be decreased by 1-Hz repetitive transcranial magnetic stimulation (rTMS) of the right Dorsolateral Prefrontal Cortex (DLPFC), presumably by effects on the emotional-cognitive component of pain. Anodal transcranial Direct Current Stimulation (tDCS) ameliorated chronic pain when applied over the motor cortex and increased working memory (WM) function in a letter-based 3-back task when applied over the left DLPFC. Thus, we investigated whether (tDCS) of the right DLPFC modulates thermal sensation or thermal pain addition to WM function. Methods: Warm and cold sensation thr…
