Inhibition of Spontaneous Lateral-line Activity by Efferent Nerve Stimulation
In common with other acoustico-lateralis receptors, the hair cells of the lateral-line organs of fishes and amphibia receive efferent innervation. Ultrastructural studies have shown that efferent synapses similar to those found at the base of the hair cells in the cochlea (Engstrom & Wersall, 1958) and vestibular system (Wersall, 1956) exist also at the base of hair cells in lateral-line organs...
متن کاملEfferent feedback slows cochlear aging.
The inner ear receives two types of efferent feedback from the brainstem: one pathway provides gain control on outer hair cells' contribution to cochlear amplification, and the other modulates the excitability of the cochlear nerve. Although efferent feedback can protect hair cells from acoustic injury and thereby minimize noise-induced permanent threshold shifts, most prior studies focused on ...
متن کاملEffect of human auditory efferent feedback on cochlear gain and compression.
The mammalian auditory system includes a brainstem-mediated efferent pathway from the superior olivary complex by way of the medial olivocochlear system, which reduces the cochlear response to sound (Warr and Guinan, 1979; Liberman et al., 1996). The human medial olivocochlear response has an onset delay of between 25 and 40 ms and rise and decay constants in the region of 280 and 160 ms, respe...
متن کاملEfferent auditory system: its effect on auditory processing.
UNLABELLED Auditory processing depends on afferent and efferent auditory pathways integrity. The efferent auditory system may be assessed in humans by two non-invasive and objective methods: acoustic reflex and otoacoustic emissions suppression. AIM Analyze the efferent auditory system activity by otoacoustic emission suppression and acoustic reflex sensitization in human subjects with audito...
متن کاملAuditory Efferent System Modulates Mosquito Hearing
The performance of vertebrate ears is controlled by auditory efferents that originate in the brain and innervate the ear, synapsing onto hair cell somata and auditory afferent fibers [1-3]. Efferent activity can provide protection from noise and facilitate the detection and discrimination of sound by modulating mechanical amplification by hair cells and transmitter release as well as auditory a...
