Investigating changes in motor activation after tDCS

[摘要] Transcranial direct current stimulation (tDCS) is a stimulation modality commonly used in motor rehabilitation research, however there is still debate surrounding the neural effects, even in healthy participants. This study thus looked to assess whether tDCS over the primary motor cortex (M1) had any significant effects on the brain motor areas in healthy right-handed participants. Within a functional magnetic resonance imaging (fMRI) scanner, a motor task, comprised move and rest blocks, was performed baseline and post stimulation. Anodal, cathodal or sham tDCS (1mA - 20 minutes) were performed on the left M1 in a within subject design (3 separate sessions per participant). Region of Interest (ROI) group baseline analysis for the contrast move>rest found the task activated all motor ROIs [p value <0.05, Family wise error (FWE) corrected]. The contrast baseline
