Figure 7

The eye movements in guinea pigs (A,B) and humans (C) in response to bone-conducted vibration (BCV). Each panel shows time series of torsional, vertical, and horizontal components of eye position in response to repeated tone bursts of 500 Hz BCV; below the traces are the mean and 95% confidence intervals (orange bars) calculated over responses to multiple stimuli. (A,B) The first line in red is the command voltage for the 500 Hz BCV stimulus. The eye movements in guinea pigs are eliminated (B) by intratympanic gentamicin which selectively attacks type I receptors. In humans (C), a small vibration applied to the mastoid (start and end time shown by the top black trace) elicits stimulus-locked torsional, vertical, and horizontal eye movements.
