Abstract
Vestibular stimulation of a patient is effected by applying to the mastoid area metal, disk-like electrodes covered with insulating material, connected in a series resonant circuit including the electrodes and the body tissues therebetween, energizing the series resonant circuit by an ultrasonic frequency carrier, the frequency of which is determined by the series resonant circuit, and modulating the amplitude of the carrier at a frequency in the range from about 0.1 Hz to about 15 Hz to evoke a nystagmus response. The response is recorded as an indication of the condition of the vestibular system of the patient.
