Self-motion perception relies on the integration of visual optic flow and vestibular signals, yet these cues are often noisy, unreliable, or mutually inconsistent. A central challenge is therefore not only how to integrate them, but also whether they should be integrated at all....

Discussion
Signed responses from readers of the wire.
No actionable change for audiology practice today; findings are basic science relevant to vestibular research but do not yet translate to clinical assessment or rehabilitation protocols.
Understanding how the brain weighs visual and vestibular cues under uncertainty advances the science underlying vestibular rehabilitation and dizziness diagnostics.
- 01The study examines causal inference as a framework for how the brain combines vision and vestibular signals.
- 02Noisy or conflicting sensory cues were used to probe the brain's integration strategy.
- 03Findings have implications for understanding multisensory dizziness and spatial disorientation.
- 04Published in Frontiers in Human Neuroscience; basic/cognitive neuroscience focus.
- 05Relevant to vestibular audiology researchers studying sensory weighting and rehabilitation.
The brain uses causal inference to decide how to integrate visual optic flow and vestibular signals for self-motion perception under noisy conditions.
