Abstract:

The sweat response from the palm an arousal sweat area is compared with that from the dorsal hand and arm a thermal sweat area during the elicitation of motion sickness by vestibular stimulation. Both palmar and dorsal sweating were detected by using galvanic skin response techniques. In addition, the dorsal sweat response was monitored by an electrochemical sweat sensor. The palmar sweat response is maximal during the first few head movements while a subject is rotating at constant velocity and quickly declines with continuation of the stimulus. This is typical of the arousal sweat response seen on the palm of the hand in response to any unusual sensory input. On the other hand, dorsal sweating has a definite latency, followed by a gradual increase in magnitude of the response. This is characteristic of most motion sickness symptomatology. With two of the eight subjects on increase in environmental temperatures was required to obtain a dorsal sweat response. This suggests that the neural activity evoked by vestibular stimulation is superimposed on that already existing as a result of the thermal state. Author
