Setting for cSP measuring and typical waveform. (a) The setting for measuring the cortical silent period (cSP). The participant was seated, and electromyography (EMG) was recorded from the right first dorsal interosseous muscle (FDI). The TMS coil was set on a hotspot for inducing motor-evoked potential (MEP) on FDI-EMG of the left primary motor cortex (M1). (b) The typical waveform of EMG in healthy participants (top) and individuals with degenerative cerebellar ataxia (DCA) (bottom). The solid triangle indicates the timing of TMS, and motor-evoked potential (MEP) appeared with approximately 20-msec latency from TMS. The cSP was detected following MEP, and reactivation appeared.
