Most fish are inherently unstable and must swim to stabilize posture. How diurnal fish reduce activity at night while maintaining postural control remains unclear. We defined distinct locomotor strategies that larval zebrafish (Danio rerio) use to control posture and navigate the water column in response to light and circadian cues....

Discussion
Signed responses from readers of the wire.
No actionable change for clinical audiology; this is a basic animal study in larval zebrafish with only indirect relevance to human vestibular function.
Understanding how circadian rhythms and light cues modulate vestibular and locomotor control in animal models may eventually inform research into dizziness disorders that vary with time of day or sleep disruption.
- 01Animal study using larval zebrafish — results may not translate directly to humans.
- 02Lighting conditions and circadian (body-clock) cues significantly influenced balance and movement strategies.
- 03Findings have implications for understanding vestibular (inner-ear balance system) postural control mechanisms.
- 04Zebrafish are a common model for vestibular and sensory research due to genetic similarities.
- 05No clinical interventions or human participants involved.
Lighting and circadian cues significantly shape locomotor strategies for balance and navigation in larval zebrafish.
