Detecting trial-specific beta band for extracting sensorimotor-related oscillatory activities. a) The reconstructed sensorimotor-related oscillatory activities in figure 3. (b) The trial-specific beta band was determined by comparing the post-movement Fourier spectrum (solid line) with the one estimated from baseline period (dashed line). (c) The subtracted spectrum and the trial-specific beta band (15~20 Hz).
