Fifty women with migrainous headaches were studied. The state of the vestibular system was assessed by ENG, including recording of spontaneous nystagmus, positional, thermal and kinetic nystagmus, recording of following of pendulum movements with eyes, and optokinetic nystagmus. ENG investigations were done in all cases between migrainous attacks, and in 20 cases also during migraine attack. During the attack in 18 women changes in the time of visual stimuli predominated, between the attacks ENG changes were observed in 24 cases.

The purpose of the study was a trial of using the calorie pendulum test and the test of reversal of the direction of caloric nystagmus with an optokinetic stimulus for assessment of the oculovestibular response in children after brain commotion. The investigations were carried out in 30 children aged from 6 to 10 years. In both tests the movements of the eyeballs were recorded with an electronystagmograph. It was found that in this type of craniocerebral trauma a transient disturbance occurs in the functions integrating the visual and vestibular stimuli in the central nervous system. It is suggested that these tests might be useful for determination of the otoneurological status of children after brain commotion.

Comprehensive treatment, including pharmacotherapy, rehabilitation, psychotherapy and ultrasound stimulation of the lymphatic system by the method of Seltzer is given to multiple sclerosis patients at the hospital department for these patients. In the first year of treatment three courses of ultrasound sessions are given with 24 sessions in each course, in the second year two such courses are given, and in the following years one course is given yearly. The present material comprised 45 patients after 7 or 8 courses of treatment in the hospital. The neurological status of each patient was evaluated before the first course and after the last one using a score scale containing the most important clinical parameters. Is was found that these therapeutic methods had only a negligible effect on paresis of the extremities, but it seems that they influenced favourably eye signs, particularly nystagmus, and cerebellar tremor. The greatest improvement was obtained in sphincter disturbances, especially in pollakiuria and urinary incontinence. The effect of ultrasound alone on the obtained results could not have been assessed. Investigations would be necessary for this purpose which are not done in this hospital.

There have been done tests of vestibulo-spinal et vestibulo- ocular reflexes at record-seeking sportsmen. At 141 sportsmen the vestibulo-spinal reflexes were tested by Unterberger-Fukuda stepping test in modification of Zilstorff-Pedersen and Peitersen. The angle of rotation (a), the distance of translocating to front or back (b) and the distance of sideward translocation (c) were estimated. The test was also done at 194 persons not playing sport. Comparing the average results of both groups the conclusion was drawn that sportsmen are characterized by lesser translocation of body within the range of all parameters of test, and differences of average are statistically substantial at the level of trust p = 0, 001. The vestibulo- ocular reflexes were tested at 62 sportsmen by caloric test by method of Fitzgerald-Hallpike with electronystagmographic registering of nystagmus. The control group consisted of 30 persons not playing sport. The following features of nystagmus were estimated: duration time, maximum frequency, maximum amplitude and maximum angular velocity of the slow phase. The sportsmen were characterized by average lesser calorie excitability of labyrinth, although the differences between the tested groups were statistically substantial only within the range of some features of nystagmus.

The subject of investigation was the possibility of the transfer of habituation. In 20 pigeons frequency of optokinetic and postrotatoric head nystagmus was established. Then in 10 birds optokinetic habituation training and in 10 remaining pigeons rotatoric habituation training were performed. After acquisition of habituation in the first group, frequency of postrotatoric head nystagmus and in the second group frequency of optokinetic head nystagmus were defined. The transfer of optokinetic habituation to the rotatoric test was confirmed. The inverted process was not observed.

The study presents a comparison of the research into results of vestibular organ stimulated with caloric tests which had been simultaneously registered with the help of a computer system of electronystagmographic examination, as well as the traditional electronystagmographic technic. In the case of 32 healthy persons there had been counted by hand average angular velocity of the slow phase caloric nystagmus average level of reduced excitability of labyrinth and direction predominance. It had been defined that those values are comparable to the ones given by the computer. That points to the right chose of the space of time in the climax of nystagmus reaction and a good identification of the phase both slow and fast by the computer system.

The estimation of the topodiagnostic value of cervical nystagmus and its changes in vertebrobasilar insufficiency was the aim of this work. The analysis was performed on 79 patients with the positive cervical nystagmus test. There was not any correlation between the side of neurologic signs, the level of CNS damage and the direction of cervical nystagmus. The changes of nystagmus direction are usefulness topodiagnostically too.

It is a description of automatic registration and analysing of the eyes movement. In this method had beed applied a test of the eye movement in the limited momentary speed, test of the time taken by the deflection and the test of unanimity in analysing both deflection and direction of the quick phase. The analysis procedure has two stages. In the first stage the signal undergoes an introductory analysis which is aimed at smoothing it out and approximating it a saw-toothed shape. At this stage the computer identifies the phases, direction of nystagmus and deflection which are not real eye deflections. In the second stage the computer makes measurements of nystagmus parameters.

The subject of investigation was the influence of ocular fixation on acquisition of habituation in experimental rotatory test in pigeons. The habituation training was performed in the three difference conditions: with full ocular fixation, fixation partly reduced and fixation excluded. Author confirmed that habituation with fixation excluded gave the best results of habituation of postural reflexes and head nystagmus in pigeons in rotatory training.

The aim of our work was the presence of the second phase nystagmus after rotatory, caloric and optokinetic irritation; estimation of this nystagmus magnitude and the clinical application of the second phase nystagmus. The investigation was performed in 30 healthy subjects and 65 cases of the peripheral and central vestibular pathology. Our results show that the second phase nystagmus appears more often after strong vestibular or visual irritation; the largeness of this reaction is bigger than the first reaction nystagmus. Only the asymmetry of the second phase nystagmus has the clinical apply. Labyrinthine disorders has the influence on the formation of the post-optokinetic reaction.
