Abstract:

Influences of the duration of angular acceleration on turning sensations and on nystagmic eye movements which can blur vision are relevant to understanding vestibular reactions during certain aircraft accelerations. Ocular recordings were obtained from human subjects and cats to 4 deg/sec/sec angular accelerations of 8.4 sec and of 36 sec duration. Lateral and vertical canals were stimulated on separate trials with output of both primary and secondary nystagmus greater for the lateral canals.

In cats, both lateral- and vertical-canal responses to 36-sec stimuli peaked and then steadily declined after 15-21 sec of angular acceleration. Declines were not apparent in nystagmus of human subjects. In an additional test, humans were given special tasks and cats received d-amphetamine with essentially the same results as described above. Other group differences were noted. Cats consistently demonstrated secondary nystagmus whereas humans did not.

After termination of acceleration, primary nystagmus from cats lasted longer and exhibited a greater number of eye movements following 8.4 sec stimuli than following 36 sec stimuli; this consistency was not evident in humans. However, for humans sensations of motion following termination of acceleration were longer for the 8.4 sec stimuli than for 36 sec stimuli. In this regard, nystagmus from cats resembled the subjective reactions of man more than they did the nystagmus of man.
