Effects of cervical dorsal root and sympathetic stimulations on the vestibular motoneurons responses recorded from the radial nerve of the cat were analysed to calrify etiological factors involved in vertigo caused by whiplash injury.<BR>The late activities of the vestibular response were attenuated during repetitive stimulation of the cervical sympathetic nerve. These activities were also inhibited by cervical dorsal root stimulation. No effect was seen in the initial spike of the vestibular response during such modulating stimulation.<BR>However, the inhibitory effect of sympathetic stimulation on the initial spikes was detected when the recovery curve of the initial spike during sympathetic stimulation was compared with that during a no stimulation period. This comparison of the two recovery curves also revealed inhibitory effects on the late activities.<BR>Based on these results, some etiological factors in vertigo as a sequelae of whiplash injury were discussed.
