tDCS changes in motor excitability are specific to orientation of current flow

Marom Bikson of CCNY states that "While orientation is long considered key in tDCS, these new results show striking sensitivity to angle of tDCS and TMS." The following paper tests the idea that the orientation of the electrodes should be considered in the targeting of brain regions during tDCS.
