Maturation of Spontaneous Firing Properties after Hearing Onset in Rat Auditory Nerve Fibers: Spontaneous Rates, Refractoriness, and Interfiber Correlations.
Auditory nerve fibers (ANFs) exhibit a range of spontaneous firing rates (SRs) that are inversely correlated with threshold for sounds. To probe the underlying mechanisms and time course of SR differentiation during cochlear maturation, loose-patch extracellular recordings were made from ANF dendrites using acutely excised rat cochlear preparations of different ages after hearing onset. Diversi...
متن کاملNerve impulses in individual auditory nerve fibers of guinea pig.
To UNDERSTAND how the cochlea analyzes and responds to complex sound stimuli, it is desirable to know what kind of message individual nerve fibers carry from the ear to the central nervous system. In 1942, Galambos and and Davis (9) recorded electric responses of single ganglion cells in the cochlear nucleus, which they once believed to be from single auditory nerve fibers. Those responses, rec...
متن کاملSpontaneous activity of auditory-nerve fibers: insights into stochastic processes at ribbon synapses.
In several sensory systems, the conversion of the representation of stimuli from graded membrane potentials into stochastic spike trains is performed by ribbon synapses. In the mammalian auditory system, the spiking characteristics of the vast majority of primary afferent auditory-nerve (AN) fibers are determined primarily by a single ribbon synapse in a single inner hair cell (IHC), and thus p...
متن کاملContribution of auditory nerve fibers to compound action potential of the auditory nerve.
Sound-evoked compound action potential (CAP), which captures the synchronous activation of the auditory nerve fibers (ANFs), is commonly used to probe deafness in experimental and clinical settings. All ANFs are believed to contribute to CAP threshold and amplitude: low sound pressure levels activate the high-spontaneous rate (SR) fibers, and increasing levels gradually recruit medium- and then...
متن کاملResponse properties of single auditory nerve fibers in the mouse.
The availability of transgenic and mutant lines makes the mouse a valuable model for study of the inner ear, and a powerful window into cochlear function can be obtained by recordings from single auditory nerve (AN) fibers. This study provides the first systematic description of spontaneous and sound-evoked discharge properties of AN fibers in mouse, specifically in CBA/CaJ and C57BL/6 strains,...
