Action Observation and Synchronization

The paper uses inter-subject phase synchronization to analyze fMRI data and identifies distinct neural networks associated with physical pain empathy, but not affective pain.

This study examines neural coupling during real-time interactions between infants and adults using fNIRS, finding increased synchronization and tracking of mutual gaze, emotion, and speech prosody.

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 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.

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.

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

The paper investigates how observing action sequences shapes neural representations in frontoparietal brain regions through fMRI and observational practice.

This study shows that improving somatosensory function before observing motor learning enhances subsequent motor performance gains from observation.

This study shows the motor system can represent multiple observed actions through fMRI, revealing a mechanism for processing social interactions.

This study uses fMRI and EEG to show the brain encodes sequence-specific motor information for predictable action sequences, suggesting the motor system implements perceptual predictive coding.

The paper investigates how social norms are inferred in humans using fMRI, finding that social congruency is represented in the mentalizing network but not in sensory areas.

This study meta-analyzes ERP studies of pain empathy, finding that P3 and late positive potential components are sensitive to pain observation, while N1 and N2 are not reliably associated, and highlights methodological issues.

Coordinate-based meta-analyses reveal a premotor, rostral parietal, and somatosensory core shared by motor imagery, action observation, and execution; only imagery and execution share putamen and cerebellum.

The paper investigates the hand action observation network in individuals born without hands, finding an intact network despite lacking the corresponding motor experience.

The paper investigates motor contagions induced by observation with or without prediction errors, finding that prediction errors lead to divergent actions rather than similarity.
