Excitation Comparison between Multi-site Stimulation using Network-based tDCS and Focal Stimulation using High-definition tDCS
Refereed conference paper presented and published in conference proceedings



摘要Transcranial direct current stimulation (tDCS) has developed rapidly recent years and derived various forms which serve as therapeutic tools for neurological disorders. However, differences among these stimulation strategies have not been fully explored. In this pilot study, we compared High-definition tDCS (HD-tDCS) and Network-based tDCS (NB-tDCS) by applying them to a healthy subject. HD-tDCS mainly stimulated primary motor cortex with 2mA current and NB-tDCS was designed to stimulate main motor-related area including primary motor cortex, premotor cortex and supplementary motor area with the same amount of current in total. Cortico-muscular coherence (CMC) of EEG/EMG collected from isometric wrist extension tasks was utilized to compare these two stimulation approaches. The results demonstrated more motor-related regions excited and longer high-level lasting effect after NB-tDCS compared with HD-tDCS, which indicates the potential power of multi-sites stimulation. This study might provide some thoughts and hints for transcranial stimulation strategies in the future.
