Aberrant three-dimensional estimates of head motion and orientation are generated by the brain when the vestibular periphery is damaged

Vertigo, defined as an abnormal perception of motion, is debilitating for millions of people, but the underlying mechanisms are not fully understood. It often arises from changes in the peripheral vestibular organs, which sense three-dimensional angular rotation, translational acceleration, and gravity....

No actionable change for immediate clinical practice — this is a mechanistic neuroscience study; however, it deepens understanding of why vestibular-damaged patients experience complex multidirectional disorientation, which may inform vestibular rehabilitation targeting in future.

Understanding exactly how the brain miscalculates head motion in three dimensions after vestibular injury could guide the development of more precise vestibular rehabilitation strategies and compensation training protocols.

1. 01Vestibular periphery damage causes the brain to generate incorrect 3-D estimates of head motion and spatial orientation.
2. 02Study characterises aberrant neural signalling patterns in multiple planes, not just a single axis of disturbance.
3. 03Findings provide mechanistic insight into why vestibular disorders produce complex, multidimensional vertigo.

5. 05Results may have downstream relevance for designing targeted vestibular rehabilitation exercises.
