Abstract Anecdotally, horses' gaits sound rhythmic. Are they really? In this study, we quantified the motor rhythmicity of horses across three different (walk, trot, and canter). For first time, adopted quantitative tools from bioacoustics music cognition to quantify locomotor rhythmicity. Specifically, tested whether kinematics data contained rhythmic categories; these occur when adjacent temporal intervals are categorically, rather than randomly, distributed. We extracted motion cycle...

Synchronous movement is a key component of social behavior in several species including humans. Recent theories have suggested link between interpersonal synchrony brain oscillations and synchrony. The present study investigated this link. Using transcranial alternating current stimulation (tACS) applied over the left motor cortex, we induced beta band (20 Hz) pairs individuals who both performed finger-tapping task with right hand. In-phase or anti-phase were delivered during preparatory...

Joint actions require the integration of simultaneous self- and other-related behaviour. Here, we investigated whether this function is underpinned by motor simulation, that capacity to represent a perceived action in terms neural resources required execute it. This was tested music performance experiment wherein on-line brain stimulation (double-pulse transcranial magnetic stimulation, dTMS) employed interfere with simulation. Pianists played right-hand part piano pieces synchrony recording...

The capacity to distinguish between one's own and others' behavior is a cognitive prerequisite for successful joint action. We employed musical action task investigate how the brain achieves this distinction. Pianists performed right-hand part of piano pieces, previously learned bimanually, while complementary left-hand either was not executed or (believed be) played by co-performer. This experimental setting served induce co-representation reflecting self Single-pulse transcranial magnetic...

Survival in a fast-changing environment requires animals not only to detect unexpected sensory events, but also react. In humans, these salient events generate large electrocortical responses, which have been traditionally interpreted within the domain. Here we describe basic physiological mechanism coupling saliency-related cortical responses with motor output. four experiments conducted on 70 healthy participants, show that substartle stimuli modulate isometric force exertion by human and...

Social interactive learning denotes the ability to acquire new information from a conspecific-a prerequisite for cultural evolution and survival. As inspired by recent neurophysiological research, here we tested whether social can be augmented exogenously synchronizing oscillatory brain activity across an instructor learner engaged in naturalistic song-learning task. We used dual stimulation protocol entailing trans-cranial delivery of synchronized electric currents two individuals...

Synchronization of neural activity across brains – interpersonal synchrony (INS) is emerging as a powerful marker social interaction that predicts success multi-person coordination, communication, and cooperation. As the origins INS are poorly understood, we tested whether how might emerge from spontaneous dyadic behavior. We recorded (EEG) human behavior (full-body kinematics, eye movements facial expressions) while dyads participants were instructed to look at each other without speaking...

Abstract Coordinated behavior promotes collaboration among humans. To shed light upon this relationship, we investigated whether and how interpersonal coordination is promoted by empathic perspective taking (EPT). In a joint music-making task, pairs of participants rotated electronic music-boxes, producing two streams musical sounds that were meant to be played synchronously. Participants – who not musically trained assigned high low EPT groups based on pre-experimental assessments using...

Abstract When people interact with each other, their brains synchronize. However, it remains unclear whether interbrain synchrony (IBS) is functionally relevant for social interaction or stems from exposure of individual to identical sensorimotor information. To disentangle these views, the current dual-EEG study investigated amplitude-based IBS in pianists jointly performing duets containing a silent pause followed by tempo change. First, we manipulated similarity anticipated change and...

Interpersonal movement synchrony (IMS) is central to social behavior in several species. In humans, IMS typically studied using structured tasks requiring participants produce specific body movements. Instead, spontaneously generated (i.e., not instructed) movements have received less attention. To test whether spontaneous synchronize interpersonally, we recorded full-body kinematics from dyads of who were only asked sit face-to-face and look at each other. We manipulated interpersonal (i)...

Overlap between sensory and motor representations has been documented for a range of human actions, from grasping (Rizzolatti et al., 1996b) to playing musical instrument (Novembre Keller, 2014). Such overlap suggests that individuals use simulation predict the outcome observed actions (Wolpert, 1997). Here we investigate as basis communication. Using turn-taking task, show pianists call on their partner's part when come in own turn. Pianists played alternating solos with videoed partner,...

Survival in a suddenly-changing environment requires animals not only to detect salient stimuli, but also promptly respond them by initiating or revising ongoing motor processes. We recently discovered that the large vertex brain potentials elicited sudden supramodal stimuli are strongly coupled with multiphasic modulation of isometric force, phenomenon we named cortico-muscular resonance (CMR). Here, extend our investigation CMR time-frequency domain. show (i) both somatosensory and...

The study of the brain mechanisms underpinning social behavior is currently undergoing a paradigm shift, moving its focus from single individuals to real-time interaction among groups individuals. Although this development opens unprecedented opportunities how interpersonal activity shapes behaviors through learning, there have been few direct connections rich field learning science. Our article examines rapidly developing neuroscience (and could be) contributing our understanding learning....

Abstract Estimating how the human body moves in space and time—body kinematics—has important applications for industry, healthcare, several research fields. Gold-standard methodologies capturing kinematics are expensive impractical naturalistic recordings as they rely on infrared-reflective wearables bulky instrumentation. To overcome these limitations, algorithms have been developed to extract from plain video recordings. This comes with a drop accuracy, which however has not clearly...
