WebJan 1, 2024 · In the synaptopathic ear (bottom schematic) many of the synaptic contacts between type-I neurons and inner hair cells have degenerated, thus many of the surviving spiral ganglion cells are silenced. The type-II spiral ganglion neurons innervating outer hair cells are unaffected, but the signals they carry likely have more to do with pain sensation … WebDec 1, 2024 · Therefore, it is of great interest to understand the mechanisms for synaptic and neuron degeneration and regeneration for the development of better ototherapeutics. We recently demonstrated that synaptopathic noise trauma is sufficient to recruit macrophages (innate-immune cells) towards the damaged inner hair cell-synaptic region.

WebCochlear synaptopathy 1 describes the loss of synapses, important neural junctions, that connect cochlear inner hair cells to the auditory nerve. Like many sensorineural hearing pathologies synaptopathy is caused by noise exposure, aging, and toxic drugs. When cochlear synapses are destroyed, the auditory nerve fibers to which they connect ... Websynaptopathic mice, there is not yet a robust diagnostic in humans. The middle-ear muscle reflex (MEMR) might be a sensitive metric (Valero et al., 2016), because low-SR fibers may be important drivers of the MEMR (Liberman and Kiang, 1984; Kobler et al., 1992).
