Chronic physical inactivity and reduced sensorimotor engagement are associated with alterations in large-scale brain network organization, often reflected as changes in resting-state functional connectivity. Interventions capable of modulating multisensory input without requiring volitional movement may therefore provide a useful experimental framework for investigating inactivity-related cortical plasticity....
No actionable change — this is a basic neuroscience study on hypergravity effects on brain networks with no direct clinical audiology or vestibular rehabilitation application at this stage.
Understanding how altered gravitational loading reshapes resting-state brain networks may offer insights into sensorimotor adaptation relevant to vestibular rehabilitation research.
- 01EEG was used to measure resting-state cortical network changes under graded hypergravity conditions.
- 02Hypergravity exposure caused large-scale reorganization of brain communication patterns.
- 03Changes were linked to a 'neurological inactivity phenotype' from reduced sensorimotor engagement.
- 04Study is basic science; direct audiology or vestibular clinical applications are indirect at best.
- 05May inform space medicine and sensorimotor neuroscience relevant to balance disorders.
Graded hypergravity causes large-scale reorganization of resting-state cortical networks as measured by EEG.
