| Outline of Final Research Achievements |
For transcranial direct current stimulation (tDCS) stimulation, electrodes are applied and secured to the scalp over the desired areas, and currents are delivered to the underlying cortical tissue. We demonstrated that Dual-tDCS (with the anodal electrode over the M1 and the cathodal electrode over the contralateral M1) enhanced cortical excitability that induced the increased amplitude of motor evoked potentials. On the other hand, Uni-tDCS (with the cathodal electrode over the contralateral orbit) was suited to improve the accuracy of visual tracking upper limb movement, compared with Dual-tDCS.
In addition, we showed that 10 min of transcranial static magnetic field stimulation (tSMS) using a powerful cylindrical neodymium, iron and boron (NdFeB) magnet can reduce the amplitude of somatosensory evoked potentials for a few minutes after magnet removal. tSMS has the potential for becoming a new non-invasive brain stimulation tool to modulate cerebral excitability.
