Editorial: New Advances in Electrocochleography for Clinical and Basic Investigation

Editorial on the Research Topic New Advances in Electrocochleography for Clinical and Basic Investigation Electrocochleography (ECochG) is a technique for recording evoked potentials from the inner ear, generally believed to originate from hair cells and nerve fibers. A major long-term goal of ECochG is to help differentiate outer hair cell (OHC) from inner hair cell (IHC) or presynaptic losses, and from auditory nerve fiber (ANF) or postsynaptic losses, which are all presently lumped together as sensorineural hearing loss. Differential diagnosis of different forms of sensorineural hearing loss could prove useful in improving hearing aid fitting, in predicting cochlear implantation outcomes, and in individualized regenerative medicine (McLean et al., 2016, 2017). Importantly, the chinchilla carboplatin studies reviewed by Salvi et al. were also among the first to provide compelling evidence for synaptic gain increases in the central auditory system in response to decreased peripheral input.
