... was observed. Without positional change, no postcaloric nystagmus was observed. These findings indicate that caloric nystagmus is modified by an adaptive process and that postcaloric nystagmus as it relates to positional change might be attributed mainly to the vestibular adaptation. 18 09 1992 5 02...

... at 43 s was always followed by a decline in response. This decay was less pronounced for the longer stimulus duration suggesting a nonreturn to the zero baseline. From a comparison with the theoretical model it can be deduced that the gain of the adaptation mechanism is less than unity. 3 07 1987...

... of the response against the logarithm of the impulse amplitude for various impulse amplitudes, i.e. the cupulometric method. Using mathematical models, with and without adaptation, we studied the effect of the two methods of calculation on the value of the response T 1 . The adaptation term was demonstrated...

...L.J.J.M. Boumans; M. Rodenburg; A.J.J. Maas The response of the human vestibulo-ocular reflex system to a constant angular acceleration is calculated using a second order model with an adaptation term. After first reaching a maximum the peracceleratory response declines. When the stimulus duration...

... with the results of the theoretical study. This form of stimulation yields a rather high value for the adaptation time constant T a , which perhaps indicates that there is an adaptation gain of less than unity. This supposition is supported by finding of non-linearity within the VOR system at high stimulus...

... transfer function which represents the VOR system. This is based on a second order differential equation for cupular behaviour, modified by an adaptation term. According to the experimental phase characteristic the cupular restoration time constant T 1 was 16.6 s, and the adaptation time constant was 114 s...

...L.J.J.M. Boumans; M. Rodenburg; A.J.J.

...M. Rodenburg; L.J.J.M. Boumans; A.J.J. Maas The influence of adaptation on the phase characteristic of both the vestibular-ocular reflex and the sensation of rotation is investigated. The experimental data can be described by a second-order model with an adaptation term. The adaptation time...
