The three pairs of semicircular canals within the labyrinth are not perfectly aligned with the pulling directions of the six extraocular muscles. Therefore, for a given head movement, the vestibulo-ocular reflex (VOR) depends upon central neural mechanisms that couple the canals to the muscles with the appropriate functional gains in order to generate a(More)
 Histograms of fast-phase intervals in human optokinetic and vestibular nystagmus were generated, and fitted to statistical distributions used in previous studies. The distributions did not depend on stimulation type (optokinetic or vestibular). An inverse Gaussian or a gamma distribution fitted the data better than did a reciprocal Gaussian distribution,(More)
Transcranial magnetic stimulation provides a mean to stimulate the brain non-invasively and painlessly. The effect of the stimulation hereby depends on the stimulation coil used and on its placement. This paper presents a mapping algorithm based on the assumption of a monotonous functional relationship between the applied electric field strength at the(More)
A reduced gain of smooth pursuit eye velocity has frequently been reported in schizophrenic patients. With respect to predictable stimuli, this could be due to a deficit in predicting the target path. To determine this contribution to smooth pursuit eye movement performance, we analyzed the ocular smooth pursuit response to a sinusoidally moving target that(More)
The term electronystagmography (ENG) refers to the recording of eye movements and nystagmus during ®xation and in response to vestibular, visual, caloric, rotational, or positional stimulation. Typically, electrooculography (EOG) is the method used to record eye movements during ENG, with the exception that the classical EOG uses DC (direct current(More)
Die Beurteilung der Sehnervenpapille mit der direkten Funduskopie gehört zu den Basistechniken für die neurologische Untersuchung. Die Wertigkeit der Untersuchung ist abhängig von der klinischen Situation gering, mäßig (Ausschluss eines erhöhten intrakraniellen Drucks vor Liquorpunktion, siehe Leitlinien der DGN) oder hoch (Diagnose und Verlaufsbeurteilung(More)
