Abstract
The response of the vestibulo-ocular reflex (VOR) system was measured after a start or stop in angular velocity around the vertical axis. All determinations were carried out six times for 5 subjects. In a previous study, the mean value of the response T1 was calculated from the slope of the decay of the slow phase eye velocity (method a) and found to be 13.2 ± (SD) 1.4 s for CW stimulation, and 12.8 ± 1.7 s for CCW stimulation. Using the cupulometric method (b) with a fixed threshold for the slow phase eye velocity, these values are 12.1 ± 2.0 and 11.2 ± 1.4 s, respectively. The difference between the values calculated by method (a) and those calculated by method (b) is in line with the theoretical predictions as formulated in section I of this paper.Keywords
