| Research Abstract |
The more efficient stimulation parameter of the repetitive TMS method was determined. The effect of stimuli is facilitatory when the stimulus interval of quadripulse stimulation(QPS) is 5 ms(QPS-5ms), and that is inhibitory when a stimulus interval is 50 ms(QPS-50ms). Moreover, we developed the probe holder of the near infrared spectroscopy(NIRS) suited to a brand-new ultralight magnetic stimulation coil, and enabled measurement of multi-channel NIRS directly under a site of the stimulus for the first time in the world. Using these systems, the online effect under magnetic stimulation was measured at the left primary motor cortex using the 2-minute QPS-5ms or QPS-50ms, and we indicated that these online-effects of QPSs were different from the long-after-effect of those.
