Verticality perception is a multisensory process that relies primarily on visual and vestibular input. Previous studies show that sensory conflict induced by optic flow causes increased errors in verticality perception. However, the time course over which sensory conflict alters verticality perception and the processes through which perceptual stability is subsequently restored, remain unknown....

Signed responses from readers of the wire.
No actionable change — this is a basic-science study on multisensory integration mechanisms; it does not yet translate to clinical vestibular assessment or rehabilitation protocols.
Understanding exactly how and how fast the brain re-weights visual versus vestibular cues during conflict could eventually inform the design of vestibular rehabilitation exercises and dizziness diagnostics.
- 01Study examined how sensitivity to verticality (sense of 'up') changes over time during visual–vestibular conflict.
- 02Conflict was induced using optic flow — moving visual patterns that suggest body tilt the inner ear does not detect.
- 03Time-course analysis reveals the dynamics of multisensory re-weighting between visual and vestibular inputs.

- 05Findings are foundational/basic science with no immediate clinical protocol implications.
Optic flow can induce a visuo-vestibular conflict that measurably alters verticality sensitivity over time.
studysupportedThe time-course of verticality sensitivity changes can be quantified and reflects multisensory integration dynamics.
