The social buffering of pain by affective touch: a laser-evoked potential study in romantic couples

Social Cognitive and Affective Neuroscience, Journal Year: 2018, Volume and Issue: unknown

Published: Sept. 22, 2018

Pain is modulated by social context. Recent neuroimaging studies have shown that romantic partners can provide a potent form of support during pain. However, such only focused on passive support, finding relatively late-onset modulation pain-related neural processing. In this study, we examined for the first time dynamic touch one's partner as an active support. Specifically, 32 couples provided social, active, affective (vs but neutral) according to properties specific C-tactile afferent pathway their partners, who then received laser-induced We measured subjective pain ratings and early N1 later N2-P2 laser-evoked potentials (LEPs) noxious stimulation, well individual differences in adult attachment style. found from reduces similarly attenuates LEPs both at earlier (N1) (N2-P2) stages cortical Adult style did not affect LEPs, anxiety had moderating role ratings.

Human attachments shape interbrain synchrony toward efficient performance of social goals

NeuroImage, Journal Year: 2020, Volume and Issue: 226, P. 117600 - 117600

Published: Nov. 26, 2020

The human brain has undergone massive expansion across primate evolution through life amidst multi-layered social attachments; within families, among friends, and between clan members this enabled humans to coordinate their brains with those of others toward the execution complex goals. We examined how attachments facilitate efficient, resource-sensitive performance goals by balancing neural behavioral synchrony. Using hyperscanning EEG, we collected data from male-female pairs in three groups (N=158, 79 pairs); long-term couples, best unfamiliar group members, during two ecologically-valid naturalistic tasks; motor coordination empathy giving. Across tasks, synchrony was supported behavior orchestrated multiple rhythms. In goal-directed task, interbrain implicated beta gamma rhythms localized sensorimotor areas. Couples showed highest combined greatest such brain-behavior linkage resulted speedy performance, conserving energy long run. socially-oriented task triggered widely-distributed bilateral temporal regions, integrated alpha, beta, rhythms, complementarity; couples displayed lowest felt support while strangers exhibited opposite pattern. Findings suggest that provide a familiar backdrop regularities, required for brain's allostatic function, are sculpted familiarity closeness survival-related goals, toiled two.

Brain mechanisms of social touch-induced analgesia in females

Pain, Journal Year: 2019, Volume and Issue: 160(9), P. 2072 - 2085

Abstract Supportive touch has remarkable benefits in childbirth and during painful medical procedures. But does social influence pain neurophysiology, ie, the brain processes linked to nociception primary experience? What other beyond systems mediate their analgesic effects? In this study, women (N = 30) experienced thermal while holding romantic partner's hand or an inert device. Social reduced attenuated functional magnetic resonance imaging activity Neurologic Pain Signature (NPS)—a multivariate pattern sensitive specific somatic pain—and increased connectivity between NPS both somatosensory “default mode” regions. Brain correlates of touch-induced analgesia included pain-related activation (1) regions targeted by nociceptive afferents (eg, posterior insula, anterior cingulate cortex); (b) associated with affective value (orbitofrontal cortex), meaning (ventromedial prefrontal cortex [PFC]), attentional regulation (dorsolateral PFC).

What binds us? Inter-brain neural synchronization and its implications for theories of human consciousness

Neuroscience of Consciousness, Journal Year: 2020, Volume and Issue: 2020(1)

Published: Jan. 1, 2020

The association between neural oscillations and functional integration is widely recognized in the study of human cognition. Large-scale synchronization activity has also been proposed as basis consciousness. Intriguingly, a growing number studies social cognitive neuroscience reveal that phase similarly appears across brains during meaningful interaction. Moreover, this inter-brain associated with subjective reports connectedness, engagement, cooperativeness, well experiences cohesion 'self-other merging'. These findings challenge standard view consciousness essentially first-person singular private. We therefore revisit recent controversy over possibility extended argue evidence fastest frequency bands overcomes hitherto most convincing sceptical position. If proposal on right track, our understanding would be profoundly transformed, we propose method to test experimentally.

Concurrent mapping of brain activation from multiple subjects during social interaction by hyperscanning: a mini-review

Quantitative Imaging in Medicine and Surgery, Journal Year: 2018, Volume and Issue: 8(8), P. 819 - 837

Social interaction plays an essential role in acquiring knowledge and developing our own personalities daily life. Meanwhile, functional magnetic resonance imaging (fMRI)-, electroencephalograph (EEG)-, near inferred spectroscopy (fNIRS)-hyperscanning, enables us to concurrently map brain activation from two or more participants who are engaged social simultaneously. In this review, we first highlight the recent technologies advances most significant findings towards by using hyperscanning method. addition, also illustrate several well-designed tasks that have been extensively adopted for study of interaction. Basically, contains six categories experimental paradigms can track interactive neural process interest. Furthermore, it main elucidated systems which involved interaction, including mirror neuron system (MNS) mentalizing (MS). Finally, future research directions clinical implications associated with highlighted discussed.

Neurobehavioral Interpersonal Synchrony in Early Development: The Role of Interactional Rhythms

Frontiers in Psychology, Journal Year: 2019, Volume and Issue: 10

Published: Sept. 18, 2019

Social interactions are essential for understanding others' actions and their mental affective states. Specifically, interpersonal coordination - also referred to as synchrony allows actors adjust behaviors one another thus demonstrate connectedness each other. Much behavioral research has demonstrated the primacy of mutually synchronized social exchanges in early development. Additionally, new methodological advances now allow us examine not only at physiological but neural level. Nevertheless, it remains unclear how infants caregivers actually achieve exchanges. Here we discuss recent evidence showing that adults provide rhythmical information during with infants, such touch singing. We propose entrainment these rhythms underlies formation stimulates reciprocal between caregivers.

HyPyP: a Hyperscanning Python Pipeline for inter-brain connectivity analysis

Social Cognitive and Affective Neuroscience, Journal Year: 2020, Volume and Issue: 16(1-2), P. 72 - 83

Published: Oct. 7, 2020

The bulk of social neuroscience takes a 'stimulus-brain' approach, typically comparing brain responses to different types stimuli, but most the time in absence direct interaction. Over last two decades, growing number researchers have adopted 'brain-to-brain' exploring similarities between patterns across participants as novel way gain insight into brain. This methodological shift has facilitated introduction naturalistic stimuli study design (e.g. movies) and, crucially, spurred development new tools directly interaction, both controlled experimental settings and more ecologically valid environments. Specifically, 'hyperscanning' setups, which allow simultaneous recording activity from or individuals during tasks, gained popularity recent years. However, currently, there is no agreed-upon approach carry out such 'inter-brain connectivity analysis', resulting scattered landscape analysis techniques. To accommodate demand standardize approaches this fast-growing research field, we developed Hyperscanning Python Pipeline, comprehensive easy open-source software package that allows (social) neuroscientists carry-out interpret inter-brain analyses.
