Microvibration-related responses to optokinetic stimulation.

The body surface of all warm-blooded animals vibrates constantly. This phenomenon was termed microvibration (MV) by ROHRACHER. Since 1961 KAWATA and students have been studying MV otolaryngologically and they detected slight changes with auditory and vestibular stimuli in the waves of MV. The authors observed changes in the MV responses in the upper extremities, in the presence of optokinetic stimulation. They found a close relationship between the direction of optokinetic stimulation and changes in the MV response. Therefore, these observations suggest that for MV recording, optic stimulation can be used to test the oculospinal reflex.
