Overview of experimental design. a: Experimental procedures. Subject underwent COP measurements at the baseline and during sham stimulation or nGVS. Rest time was set to 1 min between measurements, but 3 min between the baseline and stimulation groups. b: The stimulation conditions for each group. Fade-in and fade-out times were both set to 10 s for nGVS. We performed COP measurement after the fade-in time. nGVS, noisy galvanic vestibular stimulation; COP, center of pressure
