[Irritation of vestibular center and "ecriture centrale" (author's transl)]

To confirm the value of the écriture centrale during the pendular test clinical and animal experiments were performed. The écriture centrale was recorded in 12% of 710 subjects otoneurologically examined, mainly in groups with commotio or contusio cerebri, diseases of the brain and vertebrobasilar insufficiency. Also écriture centrale was a sign of functional disturbacne after lumbar occiptal puncture without organic lesion and in boxers. In six rabbits écriture centrale was observed after occipital puncture.

[Data processing in electronystagmography (author's transl)]

As a method for objective registration of nystagmic responses electronystagmography gives a lot of information about the state of the vestibulo-oculomotor system. Concerning accuracy, reproducibilityand objectivity the commonly used methods for diagnostic interpretation of this material are not quite satisfying. By means of a data acquistion system it is possible to utilize the advantages of the techniques of data processing. In common with fundamental considerations regarding to the choice of the parameters to evaluate the essential parts of the computer-program (calibrations, elimination of interferences, analysis of the fast and slow nystagmic components) are described and examples for the results are shown.
