Benefits and detriments of unilateral cochlear implant use on bilateral auditory development in children who are deaf

Frontiers in Psychology, 2013
We have explored both the benefits and detriments of providing electrical input through a cochlear implant in one ear to the auditory system of young children.

Envelope enhancement increases cortical sensitivity to interaural envelope delays with acoustic and electric hearing. [PDF]

PLoS ONE, 2014
Evidence from human psychophysical and animal electrophysiological studies suggests that sensitivity to interaural time delay (ITD) in the modulating envelope of a high-frequency carrier can be enhanced using half-wave rectified stimuli.

Reducing artifacts in electrically evoked auditory potentials (eAEP)

Current Directions in Biomedical Engineering
Introduction: In auditory evoked potentials (= AEP), auditory brainstem response (= ABR) is the gold standard for objective analysis of the auditory pathway using acoustical stimulators like headphones during hearing screening and patient assessment ...

Ramped pulse shapes are more efficient for cochlear implant stimulation in an animal model

Scientific Reports, 2020
In all commercial cochlear implant (CI) devices, the electric stimulation is performed with a rectangular pulse that generally has two phases of opposite polarity.

Astrocyte Hypertrophy and Microglia Activation in the Rat Auditory Midbrain Is Induced by Electrical Intracochlear Stimulation

Frontiers in Cellular Neuroscience, 2018
Neuron–glia interactions contribute to tissue homeostasis and functional plasticity in the mammalian brain, but it remains unclear how this is achieved.

Predictors for estimating subcortical EEG responses to continuous speech.

PLoS ONE
Perception of sounds and speech involves structures in the auditory brainstem that rapidly process ongoing auditory stimuli. The role of these structures in speech processing can be investigated by measuring their electrical activity using scalp-mounted ...

Effects of antioxidants on auditory nerve function and survival in deafened guinea pigs

Neurobiology of Disease, 2007
Based on in vitro studies, it is hypothesized that neurotrophic factor deprivation following deafferentation elicits an oxidative state change in the deafferented neuron and the formation of free radicals that then signal cell death pathways.

A full-custom fully implantable cochlear implant system validated in vivo with an animal model

Communications Engineering
Realizations of fully implantable cochlear implants (FICIs) for providing adequate solution to esthetic concerns and frequent battery replacement have lacked of addressing system level criteria as a complete device.

The sensitivity of different methods for detecting abnormalities in auditory nerve function

BioMedical Engineering OnLine, 2020
Background Cochlear implants (CIs) have become important for the treatment of severe-to-profound sensorineural hearing loss (SNHL). Meanwhile, electrically evoked compound action potentials (ECAPs) and electrically evoked auditory brainstem responses ...

Signaled two-way avoidance learning using electrical stimulation of the inferior colliculus as negative reinforcement: effects of visual and auditory cues as warning stimuli

Brazilian Journal of Medical and Biological Research, 1998
The inferior colliculus is a primary relay for the processing of auditory information in the brainstem. The inferior colliculus is also part of the so-called brain aversion system as animals learn to switch off the electrical stimulation of this ...
