Abstract
Transcranial direct current stimulation (tDCS) modulates cortical excitability thereby influencing behavior and learning. While previous studies focused on tDCS after-effects, limited information about “online” tDCS effects is available. This in turn is an important prerequisite to better characterize and/or optimize tDCS effects. Here, we aimed to explore the feasibility of recording low-artifact somatosensory evoked potentials (SEPs) during tDCS using a novel ring electrode setup. We recorded SEP before, during and after 10 min of anodal or sham tDCS using a full-band direct current (DC) EEG system in a total number of 3 subjects. SEPs were recorded in the bore of the tDCS ring electrode. Using this approach, no tDCS-induced artifacts could be observed after the application of a standard EEG filter. This new setup might help to better characterize how tDCS alters evoked brain responses thus providing novel insight into underlying physiological effects during stimulation. Verf.-Referat
