[HTML][HTML] The effect of ocular torsional position on perception of the roll-tilt of visual stimuli

SW Wade, IS Curthoys - Vision research, 1997 - Elsevier
Perceived postural orientation during whole-body roll-tilt is commonly inferred from settings
of a visual line to the perceived gravitational horizontal or vertical. This inference assumes …

Decreased otolith-mediated vestibular response in 25 astronauts induced by long-duration spaceflight

E Hallgren, L Kornilova, E Fransen… - Journal of …, 2016 - journals.physiology.org
