We examined the dynamics of human ocular torsion (OT) responses to sinusoidal galvanic vestibular stimulation (GVS) (0.005-1.67 Hz). The tonic OT showed a lowpass characteristic with a time constant of 1.74 s and a gain of 0.93 deg/mA. In two subjects, nystagmus dominated the observable OT pattern at frequencies <0.1 Hz. The nystagmus slow phases showed an exponential trajectory with a time constant of 1.49 s. The dynamics of both tonic OT and torsional nystagmus in our study were similar to… CONTINUE READING
