Summary: Using learning paradigms with the same total training time, this study demonstrated that the spacing effect is more robust in the adaptation of OKR than VOR, and the learning effect is also maintained longer in OKR than VOR.

Summary: This study explores whether the vestibulo-ocular reflex (VOR) gain changes in response to a clinical headshake maneuver in patients with vestibular migraine (VM). The study found that there was no significant change in VOR gain after headshaking in any group. Patients who reported nausea when reading in the passenger seat of a car were more likely to have VM.

Summary: This study aimed to evaluate the effectiveness and acceptance of Vestibulo-Ocular Reflex (VOR) adaptation training in children with recurrent vertigo. The results showed that VOR adaptation training can effectively improve vertigo symptoms and is more accepted by children compared to classic Cawthorne-Cooksey training.

Summary: The study found that high-intensity physical exertion affects clinical measures of cervical spine, vestibular/ocular motor screen, and vestibulo-ocular reflex function in athletes. Following the 30-15 Intermittent Fitness Test, athletes showed reduced left-anterolateral strength, increased dizziness, and decreased dynamic visual acuity, while other metrics did not significantly change.

Summary: The vestibulo-ocular reflex (VOR) and compensatory-saccades undergo changes after surgical unilateral vestibular deafferentation (UVD). Compensatory-saccades adapt within one week post-surgery and remain stable over one year.

Summary: The study investigated the impact of unilateral vestibular schwannoma on VOR function, finding both ipsilesional and contralesional VOR impairment in patients, with bilateral VOR impairment correlating with tumor size. Brainstem compression was associated with reduced ipsilesional VOR gain, but not contralesional VOR gain.

Summary: Incremental VOR training shows significant improvement in VOR gain, balance during gait with head rotation, and symptoms in patients with chronic peripheral vestibular hypofunction. This training method may be more effective than conventional x1 gaze-stabilizing exercises.

Summary: The study investigated the effects of noisy galvanic vestibular stimulation (nGVS) on the vestibulo-ocular reflex (VOR) and body sway. Results showed that nGVS at 0.2 mA inhibited the VOR, while nGVS at 0.6 mA increased body sway during upright standing. However, there may not be a significant relationship between these effects in healthy individuals.

Summary: This study aimed to determine the normative values of the functional head impulse test (fHIT) in healthy young adults. The results showed differences in fHIT values between different semicircular canals and genders, providing important data for future studies.

Summary: The severity of symptoms associated with vestibular schwannomas (VS) is poorly correlated with standard vestibulo-ocular reflex (VOR) metrics that are based on response amplitude. Imbalance in patients with VS scales with VOR precision and time constant, but not with VOR accuracy. Dizziness is related to the presence of a static central tone imbalance but not to any VOR metrics.

Summary: This study investigated the effect of ascorbate on the recovery of vestibulo-ocular reflex (VOR) after labyrinthectomy. The results showed that treatment with ascorbate reduced acute loss and aided in the recovery during the acute to chronic compensation stages. One possible mechanism is that ascorbate enhances the vestibulo-ocular reflex pathway, increasing the number and sensitivity of vestibular afferents.

Summary: This study examines the relationship between adaptation and compensation mechanisms in the vestibulo-ocular reflex. The results suggest that compensation affects adaptation and that these two processes are separate but overlapping. Furthermore, vestibulo-ocular reflex adaptation training is a viable treatment strategy and augments the compensatory process.

Summary: This study aims to measure the effect of carbamazepine monotherapy on the vestibular system using Video Head Impulse Test and compare the data between epilepsy patients and a healthy control group. The results show that the lateral semicircular canals' vestibulo-ocular reflex gains were reduced in patients using carbamazepine and in those using the drug for more than 10 years.

Summary: In Celsr1 KO mice, both canal- and otolith-dependent vestibulo-ocular reflexes were significantly impaired. Disorganization in the major ampullae led to a notable reduction in angular coding capacities, while mildly disorganized otolithic hair cells were associated with a loss of otolith-dependent function.

Summary: This study evaluated the diagnostic capability of visually enhanced vestibulo-ocular reflex (VVOR) gain in predicting vestibular migraine (VM) and compared the phenotypes of vestibular patients with elevated versus normal/low VVOR gain. The results showed that VVOR gain alone has limited ability to discriminate VM from other vestibular conditions. However, it was found that elevated VVOR gain may be associated with food triggers, sound sensitivity, and motion sensitivity.
