Fig. 1From: Searching for the optimal tDCS target for motor rehabilitationMotor cortex stimulation in a scenario where the left hemisphere was lesioned. Figure a Anodal stimulation of left primary motor cortex: anode over the left M1 and cathode over the right supraorbital region. Figure b Cathodal stimulation of right primary motor cortex: cathode over the right M1 and anode over the left supraorbital region. Figure c Bilateral stimulation: anode over the affected hemisphere (left) and cathode over the non-affected hemisphere (right)Back to article page
