This book was released on 1969 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this experiment was to answer specific questions relating to the design of an adaptation schedule effective in protecting against motion sickness in a rotating environment. Ten men with normal vestibular function executed controlled head and body movements at each of ten 1-rpm step increase in the velocity of the Pensacola Slow Rotation Room. On the completion of every moment, subjects were required to indicate whether or not they had detected sensations of vestibular or somatosensory origin. At each velocity step, the movements were continued until each of 24 consecutive movements had elicited a negative response and the subject was judged to be symptom free. When this arbitrary adaptation criterion was reached, the angular velocity was increased by 1 rpm and the procedure repeated. On attaining the criterion at the terminal velocity (10 rpm), the rotation was stopped and the postrotatory phenomena were investigated using the same techniques. The principal finding was that the number of movements necessary to achieve the adaptation criterion was systematically related to the absolute level of angular velocity. Considerably more head and body movements were required to reach the same level of adaptation at faster speeds than at slower speeds, even though the size of the step increment remained constant. There was some evidence to indicate that the amount of stimulation to criterion depended upon the initial magnitude of sensation elicited by the increment. There were also wide individual differences in both the rate of adaptation and the minimum velocity necessary to evoke sensation. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This investigation was concerned with estimates of the subjective strength of the Coriolis vestibular reaction evoked by 30 deg. lateral head motions at constant angular velocity in the Slow Rotation Room. In the first experiment, a power relation was obtained between geometric mean magnitude estimates of the Coriolis reaction and angular velocity. These estimates tended to be greater when vision was present than in its absence. In both conditions of visual reference, head motions evoking a pitch-forward sensation were more disturbing than those producing a pitch-back sensation. In the second experiment, it was found that the strongest reaction was produced by the return from the left shoulder (counterclockwise rotation), and the next strongest by the return from the right shoulder. Subjective rankings did not differentiate adequately between the strengths of the right and left tilt motions. (Author).

Reason and published by . This book was released on 1969 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem was to obtain a quantitative estimate of the degree of adaptation acquired as the result of different amounts of Coriolis stimulation. Subjects executed a predetermined number of controlled 90 deg. head motions at 5 rpm in the slow rotation room. Three measures of adaptation were used: (1) the number of perrotatory head movements evoking sensations due to the Coriolis acceleration, (2) the direction and duration of the Coriolis oculogyral illusion both during and immediately after the period of rotation, and (3) the number of postrotatory sensations producing some detectable after-sensation. The first measure was included to provide an indication of individual differences in adaptability; the remaining two were designed to reveal treatment effects. Six conditions of exposure, ranging from 30 to 180 sequences of eight motions each, produced no measurable differences in the degree of adaptation acquired. A positive and significant correlation was obtained between the number of perrotatory motions evoking a Coriolis reaction (irrespective of the total number of sequences executed) and the number of postrotatory motions producing an after-sensation. In a second experiment, the range of exposures was limited to 5, 10, 15, 20, and 25 sequences. Only the shortest exposure produced a measure of adaptation that was significantly less than that in the other conditions. (Author).

Download or read book Vestibular System Part 2: Psychophysics, Applied Aspects and General Interpretations written by H.H. Kornhuber and published by Springer Science & Business Media. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This compendium, written by active researchers in the field, encompasses topics ranging from anatomical and physiological subjects, through analyses of stimulus characteristics, prediction of sickness, and consideration of human factors, to pharmacological and behavioral therapeutic measures for terrestrial as well as microgravity travelers. Material often found scattered in diverse journals, paper-bound proceedings of symposia, difficult-to-find laboratory reports, or included with other topics in collections having a diffuse focus, are presented here in one volume dedicated to a single theme. The critical up-to-date- reviews are a first source for researchers and research program managers as well as an essential information source for engineers and practitioners.
