Subcortical sources dominate the neuroelectric auditory frequency-following response to speech

GM Bidelman - Neuroimage, 2018 - Elsevier
Frequency-following responses (FFRs) are neurophonic potentials that provide a window
into the encoding of complex sounds (eg, speech/music), auditory disorders, and …

Enhanced brainstem phase-locking in low-level noise reveals stochastic resonance in the frequency-following response (FFR)

B Shukla, GM Bidelman - Brain research, 2021 - Elsevier
In nonlinear systems, the inclusion of low-level noise can paradoxically improve signal
detection, a phenomenon known as stochastic resonance (SR). SR has been observed in …

Psychology meets archaeology: Psychoarchaeoacoustics for understanding ancient minds and their relationship to the sacred

J Valenzuela, M Díaz-Andreu, C Escera - Frontiers in Psychology, 2020 - frontiersin.org
How important is the influence of spatial acoustics on our mental processes related to sound
perception and cognition? There is a large body of research in fields encompassing …

Brainstem-cortical functional connectivity for speech is differentially challenged by noise and reverberation

GM Bidelman, MK Davis, MH Pridgen - Hearing research, 2018 - Elsevier
Everyday speech perception is challenged by external acoustic interferences that hinder
verbal communication. Here, we directly compared how different levels of the auditory …

Effects of noise on the behavioral and neural categorization of speech

GM Bidelman, LC Bush, AM Boudreaux - Frontiers in neuroscience, 2020 - frontiersin.org
We investigated whether the categorical perception (CP) of speech might also provide a
mechanism that aids its perception in noise. We varied signal-to-noise ratio (SNR)[clear, 0 …

Subcortical rather than cortical sources of the frequency-following response (FFR) relate to speech-in-noise perception in normal-hearing listeners

GM Bidelman, S Momtaz - Neuroscience letters, 2021 - Elsevier
Scalp-recorded frequency-following responses (FFRs) reflect a mixture of phase-locked
activity across the auditory pathway. FFRs have been widely used as a neural barometer of …

[HTML][HTML] Test–retest reliability of dual-recorded brainstem versus cortical auditory-evoked potentials to speech

GM Bidelman, M Pousson, C Dugas… - Journal of the …, 2018 - thieme-connect.com
Auditory-evoked potentials have proven useful in the objective evaluation of sound
encoding at different stages of the auditory pathway (brainstem and cortex). Yet, their utility …

Modulation masking and fine structure shape neural envelope coding to predict speech intelligibility across diverse listening conditions

V Viswanathan, HM Bharadwaj… - The Journal of the …, 2021 - pubs.aip.org
A fundamental question in the neuroscience of everyday communication is how scene
acoustics shape the neural processing of attended speech sounds and in turn impact …

Brainstem correlates of concurrent speech identification in adverse listening conditions

A Yellamsetty, GM Bidelman - Brain research, 2019 - Elsevier
When two voices compete, listeners can segregate and identify concurrent speech sounds
using pitch (fundamental frequency, F0) and timbre (harmonic) cues. Speech perception is …

[HTML][HTML] Relative contribution of envelope and fine structure to the subcortical encoding of noise-degraded speech

GM Bidelman - The Journal of the Acoustical Society of America, 2016 - pubs.aip.org
Brainstem frequency-following responses (FFR) were elicited to the speech token/ama/in
noise containing only envelope (ENV) or fine structure (TFS) cues to assess the relative …
