ROAST simulations (Voltage maps)
ROAST (Electric field map) & 2x3 optimal Electrode placement for stimulation of right MT region
Cathodal and Anodal HD-tDCS stimulation are just inverse polarity of one another
Optimal subject specific HD-tDCS electrode placement for stimulation of anatomical specific MT
