Modeling neurons in the anteroventral cochlear nucleus for amplitude modulation (AM) processing: application to speech sound
The aim of this work is to explore the representation of speech in the anteroventral cochlear nucleus by computational models based on neuroanatomical and neurophysiological data. A computational model of the anteroventral cochlear nucleus stellate cells with chop-S type response properties is described. Input that is excitatory and inhibitory to the model is in the form of simulated auditory-n...
متن کاملResponses of ventral cochlear nucleus neurons to contralateral sound following conductive hearing loss
Conductive hearing loss (CHL) is an attenuation of signals stimulating the cochlea, without damage to the auditory end organ. It can cause central auditory processing deficits that outlast the CHL itself. Measures of oxidative metabolism show a decrease in activity of nuclei receiving input originating at the affected ear, but surprisingly, an increase in the activity of second order neurons of...
متن کاملA receptive field for dorsal cochlear nucleus neurons at multiple sound levels
Neurons in the dorsal cochlear nucleus (DCN) exhibit nonlinearities in spectral processing, which make it difficult to predict the neurons' responses to stimuli. Here, we consider two possible sources of nonlinearity: non-monotonic responses as sound level increases due to inhibition; and interactions between frequency components. A spectral weighting function model of rate responses is used; t...
