Oculomotor reflexes after semicircular canal plugging in cats

J Baker, J Goldberg, B Peterson

    Brain Research
    |December 2, 1982

    Summary

    Cats with plugged semicircular canals showed absent vestibulo-ocular reflex (VOR). A compensatory cervico-ocular reflex (COR) emerged, demonstrating the brain

    Area of Science:

    • Neuroscience
    • Vestibular System
    • Ocular Motor Control

    Background:

    • The vestibulo-ocular reflex (VOR) stabilizes gaze during head movements.
    • Semicircular canals are key sensory organs for detecting angular acceleration.
    • The role of different semicircular canals in VOR and compensatory eye movements requires further elucidation.

    Purpose of the Study:

    • To investigate the impact of semicircular canal plugging on horizontal VOR in cats.
    • To examine the emergence and development of compensatory cervico-ocular reflex (COR).
    • To determine the contribution of vertical canals to horizontal eye movements when horizontal canals are dysfunctional.

    Main Methods:

    • Surgical plugging of all 6 or only horizontal semicircular canals in cats.
    • Assessment of VOR and COR before and after surgical intervention.
    • Recording of eye movements during various head rotation and pitch conditions.

    Main Results:

    • Complete plugging of semicircular canals abolished VOR, with no recovery observed.
    • A compensatory cervico-ocular reflex (COR) appeared and gradually increased in gain post-plugging.
    • Cats with plugged horizontal canals utilized vertical canals for horizontal eye movements, particularly at specific pitch angles.

    Conclusions:

    • The semicircular canals are essential for maintaining the VOR.
    • The cervico-ocular reflex (COR) can compensate for vestibular deficits.
    • Vertical semicircular canals contribute to horizontal eye movements, especially under altered vestibular conditions.
