Hearing loss and brain plasticity: the hyperactivity phenomenon

B Herrmann, BE Butler - Brain Structure and Function, 2021 - Springer
Many aging adults experience some form of hearing problems that may arise from auditory
peripheral damage. However, it has been increasingly acknowledged that hearing loss is …

Age-related changes in neural coding of envelope cues: peripheral declines and central compensation

A Parthasarathy, EL Bartlett, SG Kujawa - Neuroscience, 2019 - Elsevier
Aging listeners often experience difficulties in perceiving temporally complex acoustic cues
in noisy environments. These difficulties likely have neurophysiological contributors from …

Synaptopathy in the aging cochlea: Characterizing early-neural deficits in auditory temporal envelope processing

A Parthasarathy, SG Kujawa - Journal of Neuroscience, 2018 - Soc Neuroscience
Aging listeners, even in the absence of overt hearing loss measured as changes in hearing
thresholds, often experience impairments processing temporally complex sounds such as …

Objective evidence of temporal processing deficits in older adults

S Anderson, H Karawani - Hearing research, 2020 - Elsevier
The older listener's ability to understand speech in challenging environments may be
affected by impaired temporal processing. This review summarizes objective evidence of …

Aging alters envelope representations of speech-like sounds in the inferior colliculus

A Parthasarathy, B Herrmann, EL Bartlett - Neurobiology of aging, 2019 - Elsevier
Hearing impairment in older people is thought to arise from impaired temporal processing in
auditory circuits. We used a systems-level (scalp recordings) and a microcircuit-level …

Aging affects adaptation to sound-level statistics in human auditory cortex

B Herrmann, B Maess, IS Johnsrude - Journal of Neuroscience, 2018 - Soc Neuroscience
Optimal perception requires efficient and adaptive neural processing of sensory input.
Neurons in nonhuman mammals adapt to the statistical properties of acoustic feature …

Age-related changes in the relationship between auditory brainstem responses and envelope-following responses

A Parthasarathy, J Datta, JAL Torres, C Hopkins… - Journal of the …, 2014 - Springer
Hearing thresholds and wave amplitudes measured using auditory brainstem responses
(ABRs) to brief sounds are the predominantly used clinical measures to objectively assess …

Roles for coincidence detection in coding amplitude-modulated sounds

G Ashida, J Kretzberg, DJ Tollin - PLoS computational biology, 2016 - journals.plos.org
Many sensory neurons encode temporal information by detecting coincident arrivals of
synaptic inputs. In the mammalian auditory brainstem, binaural neurons of the medial …

Ageing affects dual encoding of periodicity and envelope shape in rat inferior colliculus neurons

B Herrmann, A Parthasarathy… - European Journal of …, 2017 - Wiley Online Library
Extracting temporal periodicities and envelope shapes of sounds is important for listening
within complex auditory scenes but declines behaviorally with age. Here, we recorded local …

Temporal coding of single auditory nerve fibers is not degraded in aging gerbils

AN Heeringa, L Zhang, G Ashida… - Journal of …, 2020 - Soc Neuroscience
People suffering from age-related hearing loss typically present with deficits in temporal
processing tasks. Temporal processing deficits have also been shown in single-unit studies …
