Vestibular pendular test was performed in 20 guinea pigs of various sexes and weights 250-300 g. The total sum of deviations on the right and on the left was 105-164. According to the standard deviation we have accepted the minimal norm 94 and maximal 183. Taking into consideration this norm we have elaborated the nomogram for the quantitative reaction to pendular excitation. There were 6 positions from 0.7 to 1.2 deviations for sec. and total sum from 94 to 183. The results in guinea pigs were in contrast with those in men. The guinea pig vestibular organ is more susceptible for high-rate excitation (17-12 degrees/sec2) and of minor susceptibility in lower rate of acceleration (12-0 degrees/sec2).
