Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, non-invasive stimulation of deep brain tissue has attracted much attention in the treatment of brain dysfunctions. One of the methods is transcranial electrical stimulation (tES). tES can be classified into transcranial direct current stimulation (tDCS), which uses direct current, and transcranial alternating current stimulation (tACS), which uses alternating current. However , the problem with these methods is that they may unnecessarily induced the electric fields in areas other than the target area. To overcome this difficulty, transcranial interference stimulation (TIS) has been proposed as a new method with higher locality even in deeper regions. This method induces an interference electric field envelope in specific parts of the brain by superimposing slightly different frequencies of alternating current above 1 kHz through two sets of electrodes attached to the head. In tES and TIS, electrodes are attached to the scalp whose positions are typically based on the international 10-10 system. However the positions of the electrodes are likely deviated from the reference position in the clinical setting. In this study, we evaluate the changes of the distributions of the electric field strength and the envelope amplitude in tACS and TIS, respectively, when a slight displacement of the electrode position is considered. The results suggest that TIS is more susceptible to the influence of the electrode attachment position than tACS, and that the electrode attachment position is more critical in TIS than in tACS.
