The paper shows that incomplete information about a partner slows collaboration learning and leads to alternating leader-follower roles, while reliable information promotes synchronous collaboration.

The paper examines the neural representation of observed actions using fMRI and finds that lateral occipitotemporal cortex and left posterior inferior parietal lobe capture the semantic dissimilarity structure of actions.

This study uses the Human Dynamic Clamp and EEG to show how sensorimotor coordination affects social cognition, revealing two neural networks linked to cooperation and humanness judgments.

This study examines how emotional valence affects parent-infant inter-brain network topology using dual-EEG data during social interactions.

This study shows that observing skilled or erroneous lifts updates participants' internal sensorimotor object representation, enabling accurate predictive force scaling during subsequent lifts.

The paper proposes a Kuramoto model to explain interpersonal synchronization strategies through self-other integration, showing how coupling strengths between and within units determine different synchronization patterns.

This study shows that observing others' hand actions activates specific cerebellar regions and that SCA6 patients have impaired ability to perceive these actions.

This study investigates age-related changes in emotional egocentric bias using neuroimaging, finding that older adults show higher bias linked to reduced connectivity in the right supramarginal gyrus.

This study shows that dual brain stimulation can enhance social interactive learning by inducing synchronized brain activity and movement between an instructor and learner.

This study shows that prior physical synchrony improves rapport and inter-brain synchronization during educational communication but does not affect word memory.

This study uses fMRI and RSA to show that lateral occipitotemporal cortex encodes perceptual components of social actions, not abstract representations of sociality.

This study uses EEG to compare sensorimotor responses to one-handed and two-handed ASL signs in deaf signers and hearing non-signers, finding differential activation patterns related to motor characteristics.

The paper investigates the neural correlates of semantic access for motor and non-motor action verbs, finding no specific role for sensorimotor cortices but noting later alpha band modulation.

The paper investigates effective connectivity in the Action Observation Network using fMRI and DCM, finding feedback connections during prediction violation.

The paper investigates how sensorimotor activity changes during the categorization of ambiguous emotional expressions using EEG, finding stronger mu suppression for neutral faces categorized as happy or sad.

The paper investigates error monitoring in human-avatar motor interactions, finding that frontal and occipito-temporal Theta activity correlates during unexpected movement violations.

The paper investigates how self-other merging affects performance in a dynamic synchronization task using a virtual partner and fMRI, showing that distinct self-other processing improves coordination.

This paper conducts a meta-analysis of fMRI studies on automatic imitation control, finding consistent activation in the multiple demand network and limited evidence for the theory-of-mind network.

The paper identifies mirror-like neurons in the rat's anterior cingulate cortex that encode both self-experienced pain and witnessed pain in others, but not fear.

The paper investigates how uncertainty in contextual and kinematic cues modulates motor resonance in primary motor cortex during movement observation.

This study investigates how humans imitate movements by analyzing stroke patients' ability to replicate trajectories using different cues, finding that dorsal premotor cortex plays a key role in abstract trajectory representation.

The paper identifies a three-component neural network involved in disambiguating objects of joint attention using fMRI data.

This study investigates mu suppression in response to dynamic facial expressions and non-biological stimuli, finding stronger mu suppression for neutral faces compared to non-biological stimuli.

This study investigates the relationship between prosocial priming, imitation, and perspective taking, finding no effect of prosocial primes on imitation and issues with the reliability of the Directors Task for measuring perspective taking.

This study examines neural representations of socio-affective touch in adults with autism, finding intact cognitive understanding but lack of embodied resonance in somatosensory areas.

The paper shows that smiling synchrony between strangers in a social setting predicts affiliative feelings and is linked to cardiovascular and emotional convergence during positive stimuli.

The paper shows that detecting hesitation in others' actions involves both mentalizing and mirror neuron systems, with motor information necessary for attributing mental states.

This study uses TMS to show that multimodal music perception with sound lagging increases cortico-spinal excitability in specific hand muscles, supporting predictive coding accounts.
