Abstract: | Background Vestibular reflexes coordinate movements or sensory input with changes in body or head position. Vestibular-evoked responses
that involve the extraocular muscles include the vestibulo-ocular reflex (VOR), a compensatory eye movement to stabilize retinal
images. Although an angular VOR attributable to semicircular canal stimulation was reported to be absent in free-swimming
zebrafish larvae, recent studies reveal that vestibular-induced eye movements can be evoked in zebrafish larvae by both static
tilts and dynamic rotations that tilt the head with respect to gravity. |
