The onset and post-onset auditory responses of cochlear nucleus neurons are modulated differently by cortical activation.

Authors: Liu X, Zhang O, Qi J, Chen A, Hu K, Yan J Abstract Auditory cortex exhibit a capacity of modulating the functions of subcortical auditory nuclei and even inner ear through descending pathways. The cochlear nucleus (CN), which acts as the gateway from the auditory periphery to the central auditory system, is also subjected to corticofugal modulation. Cortical modulation of subcortical nuclei is highly specific to the frequency tunings of cortical and subcortical neurons. It is unclear whether the high frequency-specificity of the cortical modulation of CN frequency tuning is implemented in the CN, in the auditory periphery, or in both. We analyzed the corticofugal effects on the frequency tuning, constructed from both onset (OS) and post-onset (pOS) response components of C...
