  • stimulation
  • The initial head tilt to right will cause stimulation of the right utricle resulting in excitory signals to pass to the SR and SO (right eye), and IO and IR (left eye). (wikipedia.org)
  • In case of any lesion from the utricle to the brainstem, diminished input from the affected vestibular pathway, for example the left vestibular is the same as stimulation of right vestibular pathway, resulting in the erroneous interpretation by the brain that the head is tilted to the right and consequently that the SVV is tilted to the left. (wikipedia.org)
  • This involves the simultaneous stimulation of two semicircular canals and is associated with a sudden tilting (forward or backwards) of the pilot's head while the aircraft is turning. (wikipedia.org)
  • head
  • The saccule translates head movements into neural impulses which the brain can interpret. (wikipedia.org)
  • When the head moves vertically, the sensory cells of the saccule are disturbed and the neurons connected to them begin transmitting impulses to the brain. (wikipedia.org)
  • The saccule, like the utricle, provides information to the brain about head position when it is not moving. (wikipedia.org)
  • rotation
  • Illusions involving the semicircular and somatogyral canals of the vestibular system of the ear occur primarily under conditions of unreliable or unavailable external visual references and result in false sensations of rotation. (wikipedia.org)
  • auditory
  • Research has shown, like songbirds, females in some species of fish show seasonal variation in auditory processing and the sensitivity of the saccule of females peaks during the breeding season. (wikipedia.org)
  • whereas
  • Utricle responds to linear accelerations and head-tilts in the horizontal plane (head to shoulder), whereas saccule responds to linear accelerations and head-tilts in the vertical plane (up and down). (wikipedia.org)
  • opens
  • From the lower part of the saccule a short tube, the canalis reuniens of Hensen, passes downward and opens into the ductus cochlearis near its vestibular extremity. (wikipedia.org)
  • motion
  • However, prolonged rotation (beyond 15-20 s) results in a cessation of semicircular output, and cessation of rotation thereafter can even result in the perception of motion in the opposite direction. (wikipedia.org)
