A vestibular diagnostic response.
The SP/AP ratio is a commonplace measure used in cochleography for detection of Meniere's disease (a pathology of the vestibular system). The measure is usually an averaged response to an acoustic stimulus. Franz described a process whereby the vestibular response rather than the cochlear response was used to elicit the SP/AP ratio. This paper examines that direct process. The direct process appears to detect a driven vestibular response, probably from the semicircular canals, at about 15Hz.
