Effects of Aging on Cortical Representations of Continuous Speech

This study examines how aging affects cortical processing of continuous speech in noise using MEG, finding age-related changes in timing and strength of speech envelope representations across different cortical stages.

Exaggerated Cortical Representation of Speech in Older Listeners: Mutual Information Analysis

The paper uses mutual information analysis on MEG data to show older listeners have exaggerated cortical speech representation, linked to poorer speech intelligibility and inhibitory control.

High Gamma Cortical Processing of Continuous Speech in Younger and Older Listeners

This study examines high gamma cortical responses to continuous speech in younger and older adults using MEG, finding no age-related differences in high gamma responses despite known differences in subcortical processing.

Mutual Information Analysis of Neural Representations of Speech in Noise in the Aging Midbrain

This paper uses mutual information analysis to study age-related neural deficits in speech perception, finding greater informational loss in older adults, especially with meaningful speech maskers.

Increased speech representation in older adults originates from early response in higher order auditory cortex

The paper investigates why older adults show more robust speech signal tracking in challenging conditions, finding that they recruit additional auditory regions earlier than younger adults.

Neural source dynamics of brain responses to continuous stimuli: speech processing from acoustics to comprehension

The paper demonstrates a method to analyze brain responses to continuous speech stimuli using MEG data, showing distinct neural processes for acoustic, lexical, and semantic processing.

Representation of speech in noise in the aging midbrain and cortex: aging may dominate over hearing-loss

The paper examines how aging affects speech-in-noise processing in the midbrain and cortex, finding that age-related deficits may outweigh those from hearing loss.
