a, Overlay plot of EMG signals recorded on the GN muscle when the frequency of optical pulses is 1 Hz (ON: 10 ms, OFF: 990 ms) and the irradiance is 35.4 mW mm−2. b, Plots of EMG signals recorded on the GN muscle (left) and TA muscle (right) when the frequency of optical pulses is 1 Hz and the irradiance is 35.4 mW mm−2. c, Plots of EMG signals recorded on the GN muscle when the frequency of optical pulses is 1 Hz and the irradiance is 35.4 mW mm−2 (left) or 145.0 mW mm−2 (right). d, Plots of EMG signals recorded on the GN muscle when the frequency of optical pulses is 1 Hz (left) or 40 Hz (right), and the irradiance is 35.4 mW mm−2. Blue bars indicate optical pulses from a 473-nm light source.
