Intersubject variability in VOR responses to 0.005-1.0 Hz sinusoidal rotations

Two alternate hypotheses concerning intersubject variability in normal human VOR responses were tested. Both experimental gain and phase data and linear systems parameter fits to that data supported the hypothesis that individual experimental data points varied in a systematic rather than a random fashion about ensemble mean values. A simple two parameter linear systems model was found to characterize normal data, but there was little or no correlation between the values of these two parameters, i.e., they were independent variables.
