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 …

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 …

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 …

Speech perception in noisy environments depends on complex interactions between
sensory and cognitive systems. In older adults, such interactions may be affected, especially …

Objective. Categorical perception (CP) is an inherent property of speech perception. The
response time (RT) of listeners' perceptual speech identification is highly sensitive to …

Ageing and challenging signal‐in‐noise conditions are known to engage the use of cortical
resources to help maintain speech understanding. Extensive corticothalamic projections are …

Recent research has demonstrated frontal cortical involvement to co-occur with visual re-
organization, suggestive of top-down modulation of cross-modal mechanisms. However, it is …

Mild cognitive impairment (MCI) commonly results in more rapid cognitive and behavioral
declines than typical aging. Individuals with MCI can exhibit impaired receptive speech …

Emerging evidence suggests transcranial direct current stimulation (tDCS) can improve
cognitive performance in older adults. Similarly, music listening may improve arousal and …

Background Hearing loss was proposed as a factor affecting development of cognitive
impairment in elderly. Deficits cannot be explained primarily by dysfunctional neuronal …
