Tinnitus is one of the main hearing impairments often associated with pure-tone loss, and typically manifested in perception phantom sounds. Nevertheless, tinnitus has traditionally been studied isolation without necessarily considering auditory ghosting loss as part same syndrome. Hence, present neuroanatomical study, we attempted to pave way toward a better understanding syndrome, compared two groups almost perfectly matched individuals (TIHL) (NTHL) tinnitus, but both characterized by loss. The were homogenized terms sample size, age, gender, handedness, education, Furthermore, since assessment thresholds alone not sufficient describe full spectrum abilities, also harmonized for supra-threshold estimates which collected using temporal compression, frequency selectivity und speech-in-noise tasks.

The multivariate temporal response function (mTRF) is an effective tool for investigating the neural encoding of acoustic and complex linguistic features in natural continuous speech. In this study, we investigated how representations speech derived from stimuli are related to early signs cognitive decline older adults, taking into account effects hearing. Participants without (

Minimal background noise enhances neural speech tracking: Evidence of stochastic resonance

Опубликована: Март 10, 2025

Neural activity in auditory cortex tracks the amplitude-onset envelope of continuous speech, but recent work counter-intuitively suggests that neural tracking increases when speech is masked by background noise, despite reduced intelligibility. Noise-related amplification could indicate stochastic resonance – response facilitation through noise supports tracking, a comprehensive account lacking. In five human electroencephalography (EEG) experiments, current study demonstrates generalized enhancement due to minimal noise. Results show a) enhanced for at very high SNRs (∼30 dB SNR) where highly intelligible; b) this independent attention; c) it generalizes across different stationary maskers, strongest 12-talker babble; and d) present headphone free-field listening, suggesting neural-tracking real-life listening. The paints clear picture enhances representation onset-envelope, contributes tracking. further highlights non-linearities induced make its use as biological marker processing challenging.

Cortical and behavioral tracking of rhythm in music: Effects of pitch predictability, enjoyment, and expertise

Annals of the New York Academy of Sciences, Год журнала: 2025, Номер unknown

Abstract The cortical tracking of stimulus features is a crucial neural requisite how we process continuous music. We here tested whether the beat, typically related to rhythm processing, modulated by pitch predictability and other top‐down factors. Participants listened tonal (high predictability) atonal (low music while undergoing electroencephalography. analyzed their acoustic envelope. Cortical envelope was stronger listening music, potentially reflecting listeners’ violated expectations increased attention allocation. Envelope also with more expertise enjoyment. Furthermore, showed surprisal (using IDyOM), which suggests that match those computed IDyOM model, higher for Behaviorally, measured participants’ ability finger‐tap beat sequences in two experiments. Finger‐tapping performance better condition, indicating positive effect on behavioral processing. predicted tapping as did pitch‐surprisal high low might impose different processing regimes. Taken together, our results show various ways factors impact musical

Individual theta-band cortical entrainment to speech in quiet predicts word-in-noise comprehension

Cerebral Cortex Communications, Год журнала: 2023, Номер 4(1)

Опубликована: Янв. 1, 2023

Speech elicits brain activity time-locked to its amplitude envelope. The resulting speech-brain synchrony (SBS) is thought be crucial speech parsing and comprehension. It has been shown that higher coherence associated with increased intelligibility. However, studies depending on the experimental manipulation of stimuli do not allow conclusion about causality observed tracking. Here, we investigate whether individual differences in intrinsic propensity track envelope when listening speech-in-quiet predictive speech-recognition-in-noise, an independent task. We evaluated cerebral tracking source-localized magnetoencephalography, at timescales corresponding phrases, words, syllables phonemes. found syllabic right superior temporal gyrus left middle (MTG) were positively recognition accuracy words-in-noise Furthermore, directed connectivity analysis showed this relationship partially mediated by top-down from premotor cortex-associated processing active sensing auditory domain-to MTG. Thus, extent SBS-even during clear speech-reflects mechanism system may confer resilience noise.

Successful speech comprehension, though seemingly effortless, involves complex interactions between sensory and cognitive processing is predominantly embedded in a multisensory context, providing acoustic visual cues. Adding the perspective of ageing, interaction becomes even more manyfold. The impact load on has been investigated, however, characterized by lack realistic material multimodality. In this study, we therefore investigated effects memory naturalistic immersive audiovisual comprehension older adults with varying degrees hearing impairment capacities.
