Neural activity in the auditory system synchronizes to sound rhythms, and brain-environment synchronization is thought be fundamental successful perception. Sound rhythms are often operationalized terms of sound's amplitude envelope. We hypothesized that - especially for music envelope might not best capture complex spectro-temporal fluctuations give rise beat perception synchronized neural activity. This study investigated (1) different musical features, (2) tempo-dependence synchronization, (3) dependence on familiarity, enjoyment, ease In this electroencephalography study, 37 human participants listened tempo-modulated (1-4 Hz). Independent whether analysis approach was based temporal response functions (TRFs) or reliable components (RCA), spectral flux as opposed evoked strongest synchronization. Moreover, with slower rates, high easy-to-perceive beats elicited response. Our results demonstrate importance driving highlight its sensitivity tempo, salience.

As might be enhanced by seeing musicians perform, presented audiences audio‐only (AO) audio‐visual (AV) piano performances. Only correlation measures were above chance level. time‐averaged across conditions, AV performances evoked higher inter‐subject heart rate (ISC‐HR).

Atypical audio-visual neural synchrony and speech processing in early autism

Abstract Background Children with Autism Spectrum disorder (ASD) often exhibit communication difficulties that may stem from basic auditory temporal integration impairment but also be aggravated by an audio-visual deficit, resulting in a lack of interest face-to-face communication. This study addresses whether speech processing anomalies young autistic children (mean age 3.09-year-old) are associated alterations integration.

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

Published: March 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.

Imaging the dancing brain: Decoding sensory, motor and social processes during dyadic dance

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 17, 2024

Abstract Real-world social cognition requires processing and adapting to multiple dynamic information streams. Interpreting neural activity in such ecological conditions remains a key challenge for neuroscience. This study leverages advancements de-noising techniques multivariate modeling extract interpretable EEG signals from pairs of participants engaged spontaneous dyadic dance. Using temporal response functions (mTRFs), we investigated how music acoustics, self-generated kinematics, other-generated coordination each uniquely contributed activity. Electromyogram recordings ocular, face, neck muscles were also modelled control muscle artifacts. The mTRFs effectively disentangled associated with four processes: (I) auditory tracking music, (II) movements, (III) visual monitoring partner (IV) accuracy. We show that the first three are driven by event-related potentials: P50-N100-P200 triggered acoustic events, central lateralized readiness potential movement initiation, occipital N170 observation. Notably, (previously unknown) marker encodes spatiotemporal alignment between dancers, surpassing encoding self-or partner-related kinematics taken alone. emerges when partners make contact, relies on cortical areas, is specifically observation rather than initiation. data-driven kinematic decomposition, further vertical movements best drive observers’ These findings highlight real-world neuroimaging, combined modelling, uncover mechanisms underlying complex yet natural behaviors. Significance statement brain function involves integrating streams simultaneously. However, due shortfall computational methods, laboratory-based neuroscience often examines processes isolation. modelling data freely dancing demonstrate it possible tease apart physiologically-established perception, motor produced dance partner. Crucially, identify previously unknown accuracy beyond contributions biological behaviors, advancing our understanding supports interactive activities.

Abstract Experiencing music often entails the perception of a periodic beat. Despite being widespread phenomenon across cultures, nature and neural underpinnings beat remain largely unknown. In last decade, there has been growing interest in developing methods to probe these processes, particularly measure extent which beat‐related information is contained behavioral responses. Here, we propose theoretical framework practical implementation an analytic approach capture periodicity empirical signals using frequency‐tagging. We highlight its sensitivity measuring perceived represented range continuous time‐varying with minimal assumptions. also discuss limitation this respect specificity when restricted only from magnitude spectrum signal introduce novel extension based on autocorrelation overcome issue. test new autocorrelation‐based method simulated by re‐analyzing previously published data show how it can be used process measurements brain activity as captured surface EEG adults infants response rhythmic inputs. Taken together, related methodological advances confirm elaborate frequency‐tagging promising window into processes underlying and, more generally, temporally coordinated behaviors.
