Coding-in-noise deficits are not seen in responses to amplitude modulation in subjects with cochlear synaptopathy induced by a single noise exposure

Publication date: Available online 4 January 2019Source: NeuroscienceAuthor(s): Hengchao Chen, Yazhi Xing, Zhen Zhang, Shan Tao, Hui Wang, Steve Aiken, Shankai Yin, Dongzhen Yu, Jian WangAbstractSince the first report of noise-induced synaptic damage in animals without permanent threshold shifts (PTS), the concept of noise-induced hidden hearing loss (NIHHL) has been proposed to cover the functional deficits in hearing associated with noise-induced synaptopathy. Moreover, the potential functional deficit associated with the noise-induced synaptopathy has been largely attributed to the loss of auditory nerve fibers (ANFs) with a low spontaneous spike rate (SSR). As this group of ANFs is critical for coding at suprathreshold levels and in noisy background, coding-in-noise deficit (CIND) has ...
