Which statement best describes the vestibulo-ocular reflex?

• A. It relies solely on visual input.
• B. It depends on proprioceptive cues from the neck.
• C. It is driven by auditory information to maintain gaze.
• D. It uses vestibular input to produce compensatory eye movements.

Answer: (D)

Stabilizing gaze during head movement relies on a reflex that uses inner ear signals to move the eyes in the opposite direction of head motion. When you turn or nod your head, the vestibular organs in the inner ear detect that motion and trigger eye movements that cancel it, so the image stays steady on the retina. This rapid, vestibular-driven eye movement helps you keep focus on objects even as you move.

That’s why this option is the best description: the eye movements are compensatory and driven by vestibular input, not by what you see. Visual input can influence gaze but isn’t the primary driver of the reflex, and neck proprioception supports a different reflex related to head position. Auditory information doesn’t participate in producing these compensatory eye movements.
