Gravity is a fundamental force acting on all objects on Earth. It is therefore unsurprising that the brain has internalized regularities associated with terrestrial gravity. An internal model of gravity is thought to arise from the integration of vestibular, visual, proprioceptive and visceral sensory cues....

Discussion
Signed responses from readers of the wire.
No actionable change for audiologists or vestibular clinicians; this is basic neuroscience research on gravity perception with no direct clinical application at this stage.
Understanding how the brain's internal gravity model shapes perception could eventually inform rehabilitation strategies for patients with vestibular or balance disorders.
- 01Visually simulated altered gravity changed participants' perception of object weight.
- 02Findings support the existence of an internalized brain model of terrestrial gravity.
- 03Study published in Biology Letters, a peer-reviewed Royal Society journal.
- 04Results are foundational/basic science with no immediate clinical translation.
- 05Could inform future vestibular rehabilitation or sensory reweighting research.
Visually simulated altered gravity modulates perceived object weight.
