Sociality and timing are tightly interrelated in human interaction as seen turn-taking or synchronised dance movements. also show communicative acts of other species that might be pleasurable, but necessary for survival. often co-occur, their shared phylogenetic trajectory is unknown: How, when, why did they become so linked? Answering these questions complicated by several constraints; include the use divergent operational definitions across fields species, focus on diverse mechanistic explanations (e.g., physiological, neural, cognitive), frequent adoption anthropocentric theories methodologies comparative research. These limitations hinder development an integrative framework evolutionary social make studies not fruitful could be. Here, we outline a theoretical empirical to test contrasting hypotheses evolution with species-appropriate paradigms consistent definitions. To facilitate future research, introduce initial set representative hypotheses. The proposed aims at building trees toward beyond crucial branch represented our own lineage. Given integration cross-species quantitative approaches, this research line lead integrated empirical-theoretical paradigm and, long-term goal, explain humans such socially coordinated animals.

The timing of sleep spindles is modulated by the respiratory cycle in humans

Clinical Neurophysiology, Journal Year: 2024, Volume and Issue: 166, P. 252 - 261

Published: July 9, 2024

Coupling of sleep spindles with cortical slow waves and hippocampus sharp-waves ripples is crucial for sleep-related memory consolidation. Recent literature evidenced that nasal respiration modulates neural activity in large-scale brain networks. In rodents, this respiratory drive strongly varies according to vigilance states. Whether oscillations are also respiration-modulated humans remains open. work, we investigated the influence breathing on during non-rapid-eye-movement humans. Full night polysomnography twenty healthy participants were analysed. Spindles automatically detected N2 N3 stages. Spindle-related sigma power as well spindle wave events analysed phase. We found a significant coupling between both fast cycle, enhanced occurrence probability middle part expiration A different was observed negative peaks which rather distributed around two phase transitions.

Abstract People enjoy engaging with music. Live music concerts provide an excellent option to investigate real‐world experiences, and at the same time, use neurophysiological synchrony assess dynamic engagement. In current study, we assessed engagement in a live concert setting using of cardiorespiratory measures, comparing inter‐subject, stimulus–response, correlation, phase coherence. 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). However, averaged pieces did not correspond self‐reported On other hand, time‐resolved analyses show that synchronized deceleration‐acceleration (HR) patterns, typical “orienting response” (an index directed attention), occurred within salient events section boundaries. That is, perform heightened audience structurally important moments Western classical Overall, could multisensory information shapes By different further highlight advantages time series analysis, specifically ISC‐HR, as robust measure holistic musical listening experiences naturalistic settings.

The ConNECT approach: toward a comprehensive understanding of meaningful interpersonal moments in psychotherapy and beyond

Frontiers in Human Neuroscience, Journal Year: 2025, Volume and Issue: 19

Published: March 19, 2025

Relational neuroscience struggles to capture the complex dynamics of shared interpersonal moments, leading gaps in understanding whether and how interdependencies between interacting persons translate into something meaningful. Current neuroscientific research often focuses on motor synchronization cognition rather than implicit relational qualities central psychotherapy. We argue that this disconnect stems from an over-reliance simplified quantitative methods, a failure centralize experiential factors, lack Convergence research. Drawing emerging frameworks such as 4E (embodied, enacted, extended, embedded) MoBI (Mobile Brain/Body Imaging), we advocate for integrating subjective elements with neural data. propose focusing “qualities” multi-brain neuroscience—moving beyond binary or linear scales—to better subtleties moments. Finally, emphasize importance convergence across disciplines understand what interpresence holds. If psychotherapeutic knowledge is used guide neuroscientists look for, multi-disciplinary approach holds promise advancing study psychotherapy’s processes, offering new insights neurobiology meaningful moments therapy elsewhere.

Systemic neurophysiological entrainment to behaviorally relevant rhythmic stimuli

Physiological Reports, Journal Year: 2024, Volume and Issue: 12(19)

Published: Oct. 1, 2024

Physiological oscillations, such as those involved in brain activity, heartbeat, and respiration, display inherent rhythmicity across various timescales. However, adaptive behavior arises from the interaction between these intrinsic rhythms external environmental cues. In this study, we used multimodal neurophysiological recordings, simultaneously capturing signals central autonomic nervous systems (CNS ANS), to explore dynamics of body response rhythmic auditory stimulation three conditions: baseline (no stimulation), passive processing, active processing (discrimination task). Our findings demonstrate that engagement with synchronizes both CNS ANS rhythm, unlike conditions, evidenced by power spectral density (PSD) coherence analyses. Importantly, phase angle analysis revealed a consistent alignment participants their physiological oscillatory phases at stimulus or onsets. This was associated reaction times, suggesting certain oscillations are spontaneously prioritized individuals due role sensorimotor behavior. These results highlight intricate interplay optimizing responses demands, potential mechanism embodied predictive processing.

Cardio-respiratory interactions in interoceptive perception: The role of heartbeat-modulated cortical oscillations

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2025, Volume and Issue: unknown

Published: April 19, 2025

Abstract The cardiovascular and respiratory systems are anatomically functionally integrated within the cardio-respiratory system. This close connection suggests that breathing continuously shapes cardiac interoceptive perception. Previously, we demonstrated interactions in heartbeat-evoked potential, a neural marker of cortical processing signals. Specifically, observed enhanced late potential positivity greater accuracy during exhalation compared to inhalation participants engaged tasks. Here, extended these findings time-frequency domain by reanalysing our previous dataset. We investigated heartbeat-modulated oscillations, examining power, inter-trial coherence, functional connectivity across cycle at rest, task (heartbeat counting), an exteroceptive control (cardiac-tone counting). Results revealed heartbeat counting task, heartbeat-related increased inhalation, particularly alpha theta frequency bands. These effects were primarily localized right fronto-centro-parietal electrodes. Furthermore, identified interactive relationships between oscillations band predicted accuracy. independent physiology absent task. proposed model framework predictive coding, suggesting occur multiple levels hierarchy: peripheral, brainstem, cortical. Our interpretation highlights role alpha-band modulations enhancing precision-weighting prediction errors, thereby facilitating attentional allocation signals suppression task-irrelevant distractors, exhalation.
