One-tone suppression in the cochlear nerve of the gerbil.
One-tone rate suppression has been reported several times for auditory nerve fibers of mammalian and non-mammalian vertebrates. Because its properties are very similar to those of two-tone rate suppression, the possibility exists that one-tone rate suppression is the result of an interaction within the inner ear of the suppressing tonal stimulus and some ongoing extraneous acoustic stimulus. Fo...
متن کاملMeasurement of cochlear power gain in the sensitive gerbil ear.
The extraordinary sensitivity of the mammalian ear is commonly attributed to the cochlear amplifier, a cellular process thought to locally boost responses of the cochlear partition to soft sounds. However, cochlear power gain has not been measured directly. Here we use a scanning laser interferometer to determine the volume displacement and volume velocity of the cochlear partition by measuring...
متن کاملReverse cochlear propagation in the intact cochlea of the gerbil: evidence for slow traveling waves.
The inner ear can produce sounds, but how these otoacoustic emissions back-propagate through the cochlea is currently debated. Two opposing views exist: fast pressure waves in the cochlear fluids and slow traveling waves involving the basilar membrane. Resolving this issue requires measuring the travel times of emissions from their cochlear origin to the ear canal. This is problematic because t...
متن کاملIn vivo imaging of mammalian cochlear blood flow using fluorescence microendoscopy.
AIMS We sought to develop techniques for visualizing cochlear blood flow in live mammalian subjects using fluorescence microendoscopy. BACKGROUND Inner ear microcirculation appears to be intimately involved in cochlear function. Blood velocity measurements suggest that intense sounds can alter cochlear blood flow. Disruption of cochlear blood flow may be a significant cause of hearing impairm...
متن کاملFactors controlling the input-output relationship of spherical bushy cells in the gerbil cochlear nucleus.
Despite the presence of large endbulb inputs, the spherical bushy cells (SBCs) of the rostral anteroventral cochlear nucleus do not function as simple auditory relays. We used the good signal-to-noise ratio of juxtacellular recordings to dissect the intrinsic and network mechanisms controlling the input-output relationship of SBCs in anesthetized gerbils. The SBCs generally operated close to ac...
