Rare conditions like superior canal dehiscence syndrome result in small movements of the 
eyes in response to auditory stimulation. What does this demonstrate in terms of the receptors 
and fluid in the vestibular and auditory systems? In general, what must occur in the fluid to 
activate the receptors in each system? Is conversion of the respective mechanical changes 
(pressure waves in the air or movement of the head) to electrical signals actually unique to 
each system? Briefly explain why or why not.
 

I have an idea of what the question is asking, but my thoughts aren't properly organized or I'm not even sure if they are correct.

Does this mean there is an integration of information between the two systems mentioned above and the visual system. So like sound would move through the fluid in the semicircular canal to activate the receptors.

Aren't they unique in that what causes the conversion is different but the pathway is nearly the same. Like for the auditory, air waves pressure stimulate hair cells while for the vestibular the movement of the head in either direction stimulate hair cells or starts the conversion pathway
