FDI represents the first interosseous dorsal muscle; SRTT represents the sequence reaction time task; The intensity of sensory stimulation starts at 20 μ Step A increases the amplitude of the current, and when the subject has a slight pricking sensation or visual hallucinations on the scalp, increase it by 20 μ The step size of A decreases until the stimulus current disappears in the subject's sensation.
