Electrooculographically, head turn with eyes closed may induce transient saccadic eye deviation (TSD) in the direction of the head movement as a result of activation of the lateral gaze center driven by neck torsion. TSD during active head turn has shown an incidence of 100%, a mean angle of 32.8°and a mean velocity of 163°/sec.<BR>Latencies of TSD from head turns monitored by electro-myographic bursting on the splenii capitis muscle were measured and compared with the latency (mean value of 175 msec.) of voluntary saccadic pursuit for a 10°visual angle in 12 normal subjects (aged 26 to 57 years). The mean latencies and standard deviations in active and passive head turns were 36.5±10.4 msec. and 50.9±15.6 msec., respectively, showing a significant difference (P less than 0.02). The latter should be prolonged by antecedent small vestibuloocular reflex to TSD according to a lowered alertness of the parapontine reticular formation.<BR>In conclusion, the latency of TSD may be an indicator of alertness or functional disorders of the brainstem.
