CHANGES IN SPONTANEOUS ACTIVITY AS A MEASURE OF SENSITIVITY TO ROTATION IN THE WHITE RAT,
Abstract
Fifty-six unrestrained rats were individually exposed to a rotation speed between 0-18 RPM. Their activity was measured using a fourpoint scale: (0) no activity, (1) grooming and sniffing, (2) moderate running, and (3) rapid running. Amount of activity decreased as a function of rotation speed from 6 to 14 RPM, where it reached a lower limit plateau. Rate of decline within this speed range was also directly related to velocity. Postrotation activity was suppressed up to five minutes. The rats showed considerable sensitivity to Coriolis stimuli generated during constant speed of rotation. A relationship was found between duration and magnitude of stimulation. These findings are encouraging for the use of behavioral methods in studying sensitivity to motion. (Author)
