Abstract

In normal subjects, the furosemide test reveals a diminishing magnitude of the maximum velocity of the slow component of caloric nytagmus. This phenomenon is called response decline (habituation) because of repetitive caloric stimulations. There have been many reports on the response decline phenomenon, but we have found none on the tests with the same intervals of repetition of caloric stimulation as in the furosemide test. In this study we examined 27 normal subjects to determine whether or not the response decline phenomenon occures when caloric stimulation are repeated at the same intervals as in the furosemide test but without the administration of furosemide. In the case of the repetition of the caloric test without the administration of furosemide, the magnitude of the maximum velocity of the slow component of caloric nystagmus was not so diminished than that of the frosemide test in normal subject. Therefore, we conclude that there is some cause other than response decline phenomenon to explain the diminishing of the maximum velocity of the slow component of the furosemide test in normal subjects.
