Stochastic resonance in the human vestibular system - Noise-induced facilitation of vestibulospinal reflexes.

•A new test for human vestibulospinal reflex thresholds is presented.•Evidence for stochastic resonance in the human vestibular system is provided.•Vestibular noise stimulation enables the processing of subthreshold vestibular inputs.•This effect lowers vestibulospinal reflex thresholds by in average 18%.
