    Notes: Summary 30 rabbits were turned during 30 s, and then abruptly stopped. The duration of the postrotatory nystagmus was used as parameter for the pharmacological effect. Intravenous injection of 2 mg/kg dimenhydrinate shortend the duration of postrotatory nystagmus. Contrarily 1 mg/kg thiethylperazine and 1 mg/kg dehydrobenzperidol prolonged the postrotatory nystagmus. Our experiments have shown that drugs of the same clinical effect act differently in animals. For measuring the antivertiginous effect by use of the postrotatory nystagmus criticism is indicated.

    Notes: Summary It is known that visual afferences take part in the regulation of body equilibrium. Experiments have been done to answer the question, if also optical illusions have an influence on posture. Diplopia has been produced by prisms, illusory movements by stroboscopic light effects or by a spiral disc. The influence of various optical conditions has been examined in healthy subjects and patients with a well known vestibular pathology.

    Response of central vestibular neurons to horizontal linear acceleration in the rat (1980)

    Notes: Abstract Responses of central vestibular neurons to horizontal sinusoidal translation (F:0.25 Hz) were recorded in albino rat. 57.5% of vestibular neurons were responding to this stimulation by a modulation of their firing rate, the mean phase angle of the response, averaged from the whole population being 22±79 deg. lag, relative to the peak of contralateral acceleration. Dynamic characteristics of phase and gain were studied and appeared to be different from previous reports on primary afferents: the gain decreased or was flat with increasing acceleration at one frequency, and the phase lag which was flat in the same conditions increased with increasing frequency. A phase lead of some units has been observed at low frequency (0.1 Hz). Regarding the convergence between otolith and canal inputs on nuclear vestibular neurons, it was shown that the major pattern of convergence is between canal and otolith inputs of same polarity.

    Notes: Summary In “encephale isolé-cats” evoked potentials of the vestibular projection field after stimulation of the vestibular nerve were recorded. 15 cats were injected (i.V.) with 1 or 2 mg/kg thiethylperazine. The potential amplitude was diminished by both doses from the 5th to the 60th min. In a second series (10 cats) 2 mg/kg dimenhydrinate were injected intravenously. A reduction of amplitude was seen also, which was somewhat stronger than by 1 mg/kg thiethylperazine. Our experiments have shown that both drugs have depressing effects on the vestibular system. The methode seems to be favorable for pharmacological research of antivertiginous substances.

    Notes: Summary Vestibular compensation is defined as loss of symptoms, which appear after lesion of one vestibular apparatus. It is common to understand the essential of vestibular compensation as a recovery of the „equilibrium of central vestibular tonus“. By aid of extracellular single unit recordings it could be shown, that in albino rats dynamic parameters of central vestibular neurons as gain and phase are very different in the early period after labyrinthectomy. These values are reequilibrated 14 days later.

    Notes: Summary Because of progress in early diagnosis of acoustic neuroma it is now allowed to attack the problem of preservation of hearing in operation of these tumors since the conservation of the facial nerve shows good results. This is justified by the findings, that neuromas are growing in the vestibular nerve. In retrosigmoidal approach, a modification of the suboccipital approach, the patients pontocerebellar angle is reached by a small craniotomy behind the sinus sigmoideus. The cerebellum is protected by lyophilised duramater and retracted by perfusion of mannitol. The interna 2/3 of the inner ear canal is opened by a drill. In total 40 neuromas between 12 and 45 mm were removed by this technique. In tumors until 22 mm (28 cases) it was possible to conserve cochlear function in 14 cases. Function of facial nerve is conserved in all cases but one. This technique is compared with middle fossa and translabyrinthine approach.
