[HTML][HTML] Attention reinforces human corticofugal system to aid speech perception in noise

CN Price, GM Bidelman - Neuroimage, 2021 - Elsevier
Perceiving speech-in-noise (SIN) demands precise neural coding between brainstem and
cortical levels of the hearing system. Attentional processes can then select and prioritize task …

[HTML][HTML] Brainstem speech encoding is dynamically shaped online by fluctuations in cortical α state

J Lai, CN Price, GM Bidelman - Neuroimage, 2022 - Elsevier
Experimental evidence in animals demonstrates cortical neurons innervate subcortex
bilaterally to tune brainstem auditory coding. Yet, the role of the descending (corticofugal) …

Pre-and post-target cortical processes predict speech-in-noise performance

S Kim, AT Schwalje, AS Liu, PE Gander, B McMurray… - Neuroimage, 2021 - Elsevier
Understanding speech in noise (SiN) is a complex task that recruits multiple cortical
subsystems. There is a variance in individuals' ability to understand SiN that cannot be …

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 …

Defining the role of attention in hierarchical auditory processing

CN Price, D Moncrieff - Audiology Research, 2021 - mdpi.com
Communication in noise is a complex process requiring efficient neural encoding throughout
the entire auditory pathway as well as contributions from higher-order cognitive processes …

Human auditory cortex is sensitive to the perceived clarity of speech

CJ Wild, MH Davis, IS Johnsrude - Neuroimage, 2012 - Elsevier
Feedback connections among auditory cortical regions may play an important functional role
in processing naturalistic speech, which is typically considered a problem solved through …

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] Breaking down the cocktail party: Attentional modulation of cerebral audiovisual speech processing

P Wikman, E Sahari, V Salmela, A Leminen… - NeuroImage, 2021 - Elsevier
Recent studies utilizing electrophysiological speech envelope reconstruction have sparked
renewed interest in the cocktail party effect by showing that auditory neurons entrain to …

Auditory-frontal channeling in α and β bands is altered by age-related hearing loss and relates to speech perception in noise

CN Price, C Alain, GM Bidelman - Neuroscience, 2019 - Elsevier
Difficulty understanding speech-in-noise (SIN) is a pervasive problem faced by older adults
particularly those with hearing loss. Previous studies have identified structural and functional …

Neurofeedback training of auditory selective attention enhances speech-in-noise perception

S Kim, C Emory, I Choi - Frontiers in human neuroscience, 2021 - frontiersin.org
Selective attention enhances cortical responses to attended sensory inputs while
suppressing others, which can be an effective strategy for speech-in-noise (SiN) …
