IT WAS previously admitted on the basis of observations done in animals that the functioning of the semicircular canals could be explained, even calculated, by means of some ingenious models or formulas representing their activity. Unfortunately, the knowledge in the field of the sensory mechanisms of stimulation still remains very poor today as far as vestibular as well as other receptors are concerned, like the organ of Corti. Therefore, the numerous theories issued from that conception may lead practically to important mistakes in the clinical investigations of the vestibular system. For this reason, only the stimulus and its response, that is the nystagmus taken as a signal, have to be considered.1

Since electronystagmography (ENG) was developed about 15 years ago, a new approach is functional and clinical investigations of the semicircular canals has been taken allowing to quantify the vestibular nystagmic response. To that procedure we have given the
