All of the stereocilia are mechanoreceptors, and when bent by vibrations they respond by opening a gated ion channel. As a result, the hair cell membrane is depolarized, and a signal is transmitted to the cochlear nerve. Intensity (volume) of sound is determined by how many hair cells at a particular location are stimulated.

This in turn causes neurotransmitter release at the basal end of the hair cell, eliciting an action potential in the dendrites of the VIIIth cranial nerve. Press the "play" button to see the mechanical-to-electrical transduction. Hair cells normally have a small influx of K + at rest, so there is some baseline activity in the afferent neurons. Bending the cilia toward the tallest one opens the potassium channels and increases afferent activity.

when sound bends inner hair cell's stereocilia towards shortest, ion channels close and less excitatory neurotransmitter is released to its auditory neurons -- lower auditory neuron firing rate ____ hair cells mainly send signals about sound to the brain, while ___ hair cells mainly recieve signals from the brain:

The influx of Ca2+ causes neurotransmitter release from the basal end of the hair cell to the auditory nerve endings which sends signals to the brain. Movement of the hair cells in the opposite direction causes hyperpolarization which prevents influx of K+ and closes the Ca2+ channels at the base resulting in smaller release, or no release of ...

Bending of the stereocilia toward the kinocilium (the largest of the stereocilia) opens the ion channels, leading to an inflow of ions, especially potassium, and depolarization of the hair cell. Bending of the cilia away from the kinocilium closes the ion channels and hyperpolarizes the hair cell.

The neuronal encoding of sound is the representation of auditory sensation and perception in the nervous system.. This article explores the basic physiological principles of sound perception, and traces hearing mechanisms from sound as pressure waves in air to the transduction of these waves into electrical impulses (action potentials) along auditory nerve fibers, and further processing in the ...

Bending of higher stereocilia under the influence of a sound wave causes mechanical opening of the mechanoelectrical transducer (MET) channels on the membranes of lower stereocilia by tensioning the tip of each lower stereocilium with the side wall of its associated higher one.

because sound is not transmitted from the tympanic membrane to the oval window As sound waves travel into the ear, they pass from the auditory canal to the: tympanic membrane, auditory ossicles, oval window, perilymph, scala vestibuli of the cochlea.
