Book excerpt: A direct relationship between duration of acceleration and (a) decline of response during acceleration, (b) rate of decline of response after acceleration, and (c) magnitude of secondary reaction is regarded as an indication of a central process which limits a prolonged vestibular primary reaction. The process is manifested by its influence on relatively basic reflex reactions (nystagmus) in the cat, and is more prominently manifested in man by its influence on sensory perception. (Author).

Book excerpt: Ocular nystagmus was recorded in darkness from cat and man during 4-deg/sq sec accelerations about an Earth-vertical axis. Lateral-canal stimulation yielded greater primary and secondary nystagmus than did vertical-canal stimulation. In cat, both lateral- and vertical-canal responses to a 36-second stimuli peaked after 15-21 seconds of angular acceleration, and this was followed by a steady decline. Declines during acceleration were not apparent in nystagmus of man. There was a more consistent secondary nystagmus in cat then in man. In cat, primary after-nystagmus was greater following an 8.4-second stimulus than following a 36-second stimulus. In man, a like difference occurred in the sensation but was not present in nystagmus. In this regard, nystagmus from cat resembled the subjective reactions of man more than they did the nystagmus of man. (Author).

This book was released on 1961 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under conditions in which visual cues were virtually eliminated, the box turtle (Terrapene c. carolina) responded to angular acceleration with a deviation of the head graded according to the intensity and duration of the stimulus. The head-turning continued throughout an acceleration and a subsequent deceleration served to return the head toward its normal central position. Habituation did not occur, nor could a vestibular ocular nystagmus be recorded. A similarity was found between the turtle head turning response and the slow phase of ocular nystagmus of cat and of man. (Author).

Collins and published by . This book was released on 1967 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. (Author).

Book excerpt: Turning sensations and eye movement responses during angular accelerations may show adaptation effects of significance to understanding vestibular reactions during certain aircraft maneuvers. In this study, a direct relationship found between duration of acceleration and (a) decline of response during acceleration, (b) rate of decline of response after acceleration, and (c) magnitude of secondary reaction, is regarded as an indication of a central process which limits a prolonged vestibular primary reaction. The process is manifested by its influence on relatively basic reflex reactions (nystagmus) in the cat, and is more prominently manifested in man by its influence on sensory perception. (Author).

This book was released on 2012-12-06 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: The function of the vestibular system is not as obvious as those of vision, hearing, touch or smell. Vestibular dysfunction, however, is clearly apparent where lesions are present. It is probably for this reason that the vestibular sense was not discovered until the nineteenth century and that clinicians have continued to playa major role in basic vestibular research right up to the present. The relationship between basic and clinical research is certainly stronger in the vesti bular field than in that of tactile sensation, for instance, as testified by the work of clinicians as MENIERE, BREUER, BARANY, DEKLEIJN and FRENZEL. In this respect the situation is similar in vestibular physiology and in endocrinology, and for the same reason. This second part of the vestibular volume of the Handbook of Sensory Physio logy will be of interest to neurologists, otologists, neurosurgeons, ophthalmologists and physiotherapists on the one hand, and psychologists, physiologists, engineers and aviation specialists on the other. For a full understanding of Part 2, it is necessary to have assimilated the basic anatomy, physiology, and biochemistry of Part 1.
