Age-related hearing loss may result, in part, from declining levels of γ-amino butyric acid
(GABA) in the aging inferior colliculus (IC). An upregulation of the GABA AR γ 1 subunit …

The age-related loss of GABA in the inferior colliculus (IC) likely plays a role in the
development of age-related hearing loss. Perineuronal nets (PNs), specialized aggregates …

Neural oscillations at specific frequency bands are associated with cognitive functions and
can identify abnormalities in cortical dynamics. In this study, we analyzed EEG signals …

Background Two challenges in auditory fMRI include the loud scanner noise during sound
presentation and slow data acquisition. Here, we introduce a new auditory imaging protocol …

The aim of this work was to investigate the perceptual relevance of the frequency following
response to the syllable/da/for speech intelligibility in noise based on age and hearing …

The balance between neural excitation and inhibition has been shown to be crucial for
normal brain function. However, it is unclear whether this balance is maintained through …

One way to investigate the mechanisms that underlie speech comprehension under difficult
listening conditions is via cortical connectivity. The innovative Network Localized Granger …

In social settings, speech waveforms from nearby speakers mix together in our ear canals.
The brain unmixes the attended speech stream from the chorus of background speakers …

This study investigates the role of hearing sensitivity, age and supra-threshold hearing to
speech recognition in quiet, stationary, and modulated noise. Three participant groups were …

Optimal speech perception in noise requires successful separation of the target speech
stream from multiple competing background speech streams. The ability to segregate these …
