Cerebral vestibular-evoked potentials depend on body orientation

Otolithic vestibular receptors encode linear acceleration and head orientation relative to gravity, providing a fundamental reference signal for perception, action, and higher-order cognitive functions. However, the cerebral dynamics of otolithic information processing and their sensitivity to body orientation remain poorly characterized....

No actionable change for current clinical practice; this is basic neurophysiology research that may inform future vestibular testing protocols but has no immediate diagnostic or treatment implications.

Understanding how body orientation shapes cortical vestibular responses could refine the design and interpretation of vestibular-evoked potential tests used in balance disorder assessment.

1. 01Cerebral vestibular-evoked potentials (cVEPs) vary systematically with body orientation.
2. 02Otolithic receptors encode both linear acceleration and head-to-gravity orientation, contributing to this variability.
3. 03Findings suggest body position is a critical, often uncontrolled variable in vestibular evoked potential recordings.
4. 04Results are published in Journal of Neurophysiology (DOI: 10.1152/jn.00116.2026).
5. 05Study is foundational/basic science; clinical translation will require further research.
