| Outline of Final Research Achievements |
In the present study, we investigated whether anodal transcranial direct current stimulation (tDCS) application to motor cortex is affected differential of current intensity or electrode position. The anodal electrode was placed on the left scalp over the primary motor area (M1). The cathodal electrode was placed above the right scalp over the orbit or right M1 (unilateral tDCS and bilateral tDCS, respectively). All subjects underwent the following four interventions: unilateral tDCS or bilateral tDCS delivered with 1 mA and 2 mA for 10 min. Motor evoked potentials (MEPs) were recorded before and 2 min and 10 min after intervention. As results, under the bilateral_2 mA condition, the MEP at 2 min and 10 min after intervention were significantly increased compared with those before the intervention. Under the other conditions, the MEP remained unchanged. These results demonstrated that anodal tDCS is highly affected differential of current intensity or electrode position.
