The goal was to test whether band-limited sensory noises with adequate amplitudes, by the principle of stochastic resonance, could enhance μ and β wave suppressions. Scalp EEG was recorded while the subject performed thumb movements in the presence of vibratory noises applied to thenar belly or thumb tip. Seven subjects without clear μ or β wave suppression in the absence of the mechanical stimuli were recruited. The results showed that when the stimuli were applied to the thenar belly, both μ and β wave suppressions were enhanced in a bell-shaped trend (the characteristics of stochastic resonance) in four subjects.
