The rat vestibular system plays a critical role in anti-gravity responses such as the tail-lift reflex and the air-righting reflex. In a previous study in male rats, we obtained evidence that these two reflexes depend on the function of non-identical populations of vestibular sensory hair cells (HC)....

Discussion
Signed responses from readers of the wire.
No actionable change for clinical practice — this is an animal model study characterising vestibular hair cell loss and is too preliminary to inform patient management.
Identifying the specific vestibular hair cell type responsible for functional balance deficits after ototoxicity could eventually guide the development of targeted protective or regenerative therapies.
- 01Ototoxicity (drug-related inner-ear damage) in rats selectively destroyed vestibular type I hair cells.
- 02Loss of type I hair cells was linked to deficits in tail-lift and air-righting reflexes — standard balance tests in rodents.
- 03The study provides a functional correlate for type I vestibular hair cell loss.

- 05Findings are limited to an animal model and require translation to human vestibular disease.
Ototoxicity-induced loss of vestibular type I hair cells causes deficits in tail-lift and air-righting reflexes in rats.
studysupportedType I hair cell loss is the primary driver of ototoxicity-related vestibular functional decline.
