Oculogyral Illusions

• When the somatogyral illusion is strong, or visual cues are lacking,
• The brain "adjusts" visual perception to see the movement that the semicircular canals say is happening.
  • The instrument panel may appear to move;
  • The sky or lights on the ground may seem to tilt or turn.
  • This delays recognition of the illusion.
• This is like the "oculogravic" illusion, which operates in response to otolith sensations
