Abstract
Using the rotary apparatus of the positional table system, the author gave centrifugal force to labyrinths and observed with ENG how the nystagmus response caused by caloric stimulus goes on.
In a supine position there rises a difference in intensity of caloric nystagmus between the two opposite directions of the rotation, while in a lateral position caloric nystagmus is not affected even when under centrifugal force.
Consequently the author proposes the possibility of the influence of centrifugal force on the otolithorgans. These observations indicate that the intensity of caloric nystagmus directed to the side where pressure is given to saccular macula decreases.
