Effects of Stimulation Rate, Mode and Level on Modulation Detection by Cochlear Implant UsersJournal of the Association for Research in Otolaryngology - Tập 6 - Trang 269-279 - 2005
John J. Galvin, Qian-Jie Fu
In cochlear implant (CI) patients, temporal processing is often poorest at low
listening levels, making perception difficult for low-amplitude temporal cues
that are important for consonant recognition and/or speech perception in noise.
It remains unclear how speech processor parameters such as stimulation rate and
stimulation mode may affect temporal processing, especially at low listening
levels... hiện toàn bộ
Effects of Hearing Preservation on Psychophysical Responses to Cochlear Implant StimulationJournal of the Association for Research in Otolaryngology - Tập 11 - Trang 245-265 - 2009
Stephen Y. Kang, Deborah J. Colesa, Donald L. Swiderski, Gina L. Su, Yehoash Raphael, Bryan E. Pfingst
Previous studies have shown that residual acoustic hearing supplements cochlear
implant function to improve speech recognition in noise as well as perception of
music. The current study had two primary objectives. First, we sought to
determine how cochlear implantation and electrical stimulation over a time
period of 14 to 21 months influence cochlear structures such as hair cells and
spiral gangl... hiện toàn bộ
Polygenic Risk Score-Based Association Analysis of Speech-in-Noise and Hearing Threshold Measures in Healthy Young Adults with Self-reported Normal HearingJournal of the Association for Research in Otolaryngology - Tập 24 - Trang 513-525 - 2023
Ishan Sunilkumar Bhatt, Sai Kumar Ramadugu, Shawn Goodman, Srividya Grama Bhagavan, Valerie Ingalls, Raquel Dias, Ali Torkamani
Speech-in-noise (SIN) traits exhibit high inter-subject variability, even for
healthy young adults reporting normal hearing. Emerging evidence suggests that
genetic variability could influence inter-subject variability in SIN traits.
Genome-wide association studies (GWAS) have uncovered the polygenic architecture
of various adult-onset complex human conditions. Polygenic risk scores (PRS)

Knock-in Mouse Model for Resistance to Thyroid Hormone (RTH): An RTH Mutation in the Thyroid Hormone Receptor Beta Gene Disrupts Cochlear MorphogenesisJournal of the Association for Research in Otolaryngology - - 2002

Thyroid hormone and the beta isoform of its receptor, Trb, are essential for
normal development of the mammalian auditory system. We have analyzed auditory
system function and structure in a mouse strain with a targeted Thrb mutation,
ThrbPV, which leads to the loss of binding of thyroid hormone (T3) to the Trb
protein. Heterozygosity for the orthologous human THRBPV mutation and other
similar mut... hiện toàn bộ
Disruption of Lateral Olivocochlear Neurons via a Dopaminergic Neurotoxin Depresses Sound-Evoked Auditory Nerve ActivityJournal of the Association for Research in Otolaryngology - Tập 6 - Trang 48-62 - 2005
Colleen G. Le Prell, KÄrin Halsey, Larry F. Hughes, David F. Dolan, Sanford C. Bledsoe
We applied the dopaminergic (DA) neurotoxin
1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to the guinea pig cochlear
perilymph. Immunolabeling of lateral olivocochlear (LOC) neurons using
antibodies against synaptophysin was reduced after the MPTP treatment. In
contrast, labeling of the medial olivocochlear innervation remained intact. As
after brainstem lesions of the lateral superior olive... hiện toàn bộ
Experimental Evidence for a Cochlear Source of the Precedence EffectJournal of the Association for Research in Otolaryngology - Tập 14 Số 5 - Trang 767-779 - 2013
Bianchi, Federica, Verhulst, Sarah, Dau, Torsten
The precedence effect (PE) refers to the dominance of directional information
carried by a direct sound (lead) over the spatial information contained in its
multiple reflections (lags) in sound localization. Although the processes
underlying the PE have been largely investigated, the extent to which peripheral
versus central auditory processes contribute to this perceptual phenomenon has
remained ... hiện toàn bộ
Perceptual Weighting of Binaural Lateralization Cues across Frequency BandsJournal of the Association for Research in Otolaryngology - Tập 21 - Trang 485-496 - 2020
Axel Ahrens, Suyash Narendra Joshi, Bastian Epp
The auditory system uses interaural time and level differences (ITD and ILD) as
cues to localize and lateralize sounds. The availability of ITDs and ILDs in the
auditory system is limited by neural phase-locking and by the head size,
respectively. Although the frequency-specific limitations are well known, the
relative contribution of ITDs and ILDs in individual frequency bands in
broadband stimul... hiện toàn bộ
