SnapShot: Auditory Transduction
role in alerting us to nearby activities, in the appreciation of music, and especially in human communication. Airborne sounds vibrate the tympanum, which transmits the oscillations successively to the malleus, incus, and stapes of the middle ear. Moving like a piston, the last of these miniscule bones alternately increases and decreases the pressure within the cochlea, a chickpea-sized organ t...
متن کاملSensory transduction and adaptation in inner and outer hair cells of the mouse auditory system.
Auditory function in the mammalian inner ear is optimized by collaboration of two classes of sensory cells known as inner and outer hair cells. Outer hair cells amplify and tune sound stimuli that are transduced and transmitted by inner hair cells. Although they subserve distinct functions, they share a number of common properties. Here we compare the properties of mechanotransduction and adapt...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
The transduction channel filter in auditory hair cells.
In the first step in auditory transduction, sound-induced vibrations of the stereociliary bundles on the sensory hair cells are converted into electrical signals by opening of mechanotransducer channels. Faithful transduction and hence auditory performance will be limited by the kinetic properties of these channels. We have measured the time course of mechanotransducer currents in turtle and ra...
متن کاملSimulation of mechanical to neural transduction in the auditory receptor.
A probabilistic model is described for transmitter release from hair cells, auditory neuron EPSP's, and discharge patterns. The model assumes that the release fraction of the transmitter is a function of stimulus intensity. It further assumes that some of this transmitter substance is taken back into the cell while some is irretrievably lost from the cleft. These assumptions differ from other r...
