Swung and spun in weightlessness : Evidence of immediate canalar underdetection of rotations in parabolic flight

The paper assesses semicircular canal function during parabolic flight by measuring VOR responses and finds reduced VOR gain in microgravity, with post-flight effects suggesting multisensory integration changes.

Turning green in microgravity: facial color changes as best physiological indicator of space sickness

This study investigates physiological indicators of motion sickness, finding that increased skin greenness correlates with motion sickness severity in different sensory conflict scenarios.

Visual and vestibular reweighting after cyber- and space-sickness

This study examines how visual and vestibular reweighting occurs after exposure to different sensory conflict paradigms and finds that sensitivity to the stimulated modality determines susceptibility to motion sickness.

Ancestral persistence of vestibulo-spinal reflexes in axial muscles in humans

This study investigates vestibulo-spinal reflexes in axial muscles, showing they persist in microgravity and during head contact, unlike limb muscles, suggesting a hard-wired reflex for posture control.
