Envelope following response measurements in young veterans are consistent with noise-induced cochlear synaptopathy

NF Bramhall, GP McMillan, SD Kampel - Hearing Research, 2021 - Elsevier
Animal studies have demonstrated that noise exposure can lead to the loss of the synapses
between the inner hair cells and their afferent auditory nerve fiber targets without impacting …

The derived-band envelope following response and its sensitivity to sensorineural hearing deficits

S Keshishzadeh, M Garrett, V Vasilkov, S Verhulst - Hearing research, 2020 - Elsevier
The envelope following response (EFR) has been proposed as a non-invasive marker of
synaptopathy in animal models. However, its amplitude is affected by the spread of basilar …
