“…Experimental works on VOR habituation in animals also showed a decrease in gain and a increased phase advance (Baloh et al 1982;Blair and Gavin 1979;Clement et al 2002;Jäger and Henn 1981). Similar results were observed in umans performing ballet (Osterhammel et al 1968;Tschiassny 1957) and gymnastics (Quarck and Denise 2005). The VOR modiWcations observed in the skaters are thus in agreement with experimental works on habituation of the vestibular system in humans and animals.…”

“…A number of studies have been devoted, with sometimes conXicting results, to highlighting vestibular habituation in populations engaged in activities that produce powerful stimulation of the vestibular apparatus. In ballet dancers, the vestibular response appears shorter (Tschiassny 1957) and the nystagmus slow phase velocity is lower (Osterhammel et al 1968). The VOR of gymnasts is characterized by a 15% shortening of TC and by a 25% decrease gain with an asymmetry producing a more marked decrease in counterclockwise rotation (Quarck and Denise 2005).…”

Vestibulo-ocular reflex and motion sickness in figure skaters

et al. 2008

In order to determine the effect of figure skating on the functional plasticity of the vestibular system, we quantified vestibulo-ocular reflex (VOR) and motion sickness (MS) intensity in 11 female figure skaters and 11 matched control subjects. Vestibular stimulation consisted of three cycles of sinusoidal rotation (0.025 Hz, +/-60 degrees /s) and two velocity steps of 60 degrees /s (acceleration 60 degrees /s(2)). Nauseogenic stimulation consisted of a constant velocity (60 degrees /s) off vertical axis rotation (OVAR) using a 15 degrees tilt angle. Subjective sickness symptoms were rated immediately after OVAR with the Pensacola diagnostic index. During sinusoidal stimulations, the skaters' VOR, as compared with that of the controls, demonstrates a gain that is 27% lower (0.44 +/- 0.12 vs. 0.58 +/- 0.10; P < 0.01) and a phase advance (10 +/- 12 degrees vs. -0.3 +/- 6.4 degrees ; P < 0.05). During velocity steps, the VOR gain is 32% lower among the skaters (0.52 +/- 0.14 vs. 0.71 +/- 0.12; P < 0.01), but there is no difference in time constant (10.8 +/- 1.8 s vs. 10.5 +/- 2.7 s; P = 0.78). Nauseogenic stimulation evokes significantly less MS in figure skaters than in control subjects (2.8 +/- 2.8 vs. 16.2 +/- 13.7; P < 0.01). Quantitative alterations in VOR parameters observed in figure skaters probably result from vestibular habituation induced by repeated unusual stimulations when practicing figure skating.

“…Why ultrashort time constants should develop in B4 and B6 is unclear, but one explanation is that this phenomenon is a form of activity-dependent habituation of the vestibular signal (Jager and Henn 1981;Loomis et al 2001;Osterhammel et al 1968;Thinus-Blanc and Gaunet 1997;Ungar et al 1995Ungar et al , 1997b. Alternatively, inherently shorter vestibular time constants in some subjects could have promoted their predilection to physical activity, but the available evidence indicates that activity shortens vestibular time constants (Grunfeld et al 2000;Jager and Henn 1981;Osterhammel et al 1968) not the other way round. Whatever the relationship between physical activity and the perceptual vestibular time constant, it is likely that cerebellar mechanisms, with their prominent roles in vestibular processing, motor control, and neural plasticity (Ungerleider et al 2002), must have played a part.…”

Vestibular input is required for accurate locomotion in the dark, yet blind subjects' vestibular function is unexplored. Such investigation may also identify visually dependent aspects of vestibular function. We assessed vestibular function perceptually in six congenitally blind (and 12 sighted) subjects. Cupula deflection by a transient angular, horizontal acceleration generates a related vestibular nerve signal that declines exponentially with time constant approximately 4-7 s, which is prolonged to 15 s in the evoked vestibular-ocular reflex by the brain stem "velocity storage." We measured perceptual velocity storage in blind subjects following velocity steps (overall perceptual vestibular time constant, experiment 1) and found it to be significantly shorter (5.34 s; range: 2.39-8.58 s) than in control, sighted subjects (15.8 s; P < 0.001). Vestibular navigation was assessed by subjects steering a motorized Bárány-chair in response to imposed angular displacements in a path-reversal task, "go-back-to-start" (GBS: experiment 2); and a path-completion task, "complete-the-circle" (CTC: experiment 3). GBS performances (comparing response vs. stimulus displacement regression slopes and r(2)) were equal between groups (P > 0.05), but the blind showed worse CTC performance (P < 0.05). Two blind individuals showed ultrashort perceptual time constants, high lifetime physical activity scores and superior CTC performances; we speculate that these factors may be inter-related. In summary, the vestibular velocity storage as measured perceptually is visually dependent. Early blindness does not affect path reversal performance but is associated with worse path completion, a task requiring an absolute spatial strategy. Although congenitally blind subjects are overall less able to utilize spatial mechanisms during vestibular navigation, prior extensive physical spatial activity may enhance vestibular navigation.

“…The VOR has been thoroughly investigated to better understand the vestibular input to oculomotor mechanisms (e.g., Kingma et al 2001). Interestingly, changes in VOR characteristics such as a lower gain (ratio between compensatory slow phase eye velocity and head angular velocity) have been found in ice skaters (Alpini et al 2009; Tanguy et al 2008), ballet dancers (Osterhammel et al 1968; Tschiassny 1957), and gymnasts (Quarck and Denise 2005). What these experts have in common is that self-motion perception plays an important role for their skills.…”

Self-motion perception training: thresholds improve in the light but not in the dark

et al. 2013

We investigated perceptual learning in self-motion perception. Blindfolded participants were displaced leftward or rightward by means of a motion platform, and asked to indicate the direction of motion. A total of eleven participants underwent 3360 practice trials, distributed over twelve (Experiment 1) or six days (Experiment 2). We found no improvement in motion discrimination in both experiments. These results are surprising since perceptual learning has been demonstrated for visual, auditory, and somatosensory discrimination. Improvements in the same task were found when visual input was provided (Experiment 3). The multisensory nature of vestibular information is discussed as a possible explanation of the absence of perceptual learning in darkness.
