Action Observation and Synchronization

This study identifies mirror neuron populations in sensorimotor cortices that represent grip force and reward expectation during manual and observational tasks in non-human primates.

The paper shows that viewing ambiguous social interactions increases connectivity between frontal and temporal brain regions in monkeys.

This study investigates how parietal cortex represents different action classes, finding a region specific to human indirect communicative actions and higher discriminability of action classes in parietal cortex compared to other regions.

This study compares sensorimotor brain activity during sign imitation between deaf signers and hearing non-signers, finding earlier and more robust differentiation in deaf signers.

This paper decodes grasp typicality from hand-selective brain regions during real tool grasping, showing these regions encode how to grasp 3D tools even without tool use or object knowledge.

This study uses inter-brain synchrony as neurofeedback to enhance social interaction, showing increased synchrony at theta frequency and correlations with subjective reports.

This study shows that synchronous caregiving from birth to adulthood shapes the neural basis of empathic accuracy in humans.

The paper investigates whether motor resonance is modulated by an object's weight distribution and finds that it is, during both observation and planning of lifting actions.

The paper shows that observing lifts of objects conveys weight distribution information, improving digit positioning strategies, but only error observations enhance predictive motor control for unexpected weight distributions.

The paper shows that frontoparietal and cerebellar networks are crucial for predicting intentions in altered perceptual conditions, especially when visual representations are spatially and temporally modified.

This study investigates whether placebo analgesia affects empathy for pain by examining neural responses to naturalistic depictions of others' pain in a somatotopically matched manner.

The paper shows that facing-body stimuli enhance neural activity in visual areas processing body motion and spatial relations, improving perceptual accuracy and functional integration.

The paper investigates how direct versus averted eye gaze affects motor evoked potentials and mu rhythm suppression during action observation, finding both are modulated by gaze direction.

The paper shows that action verbs and observed actions share a neural substrate in human posterior parietal cortex, with invariant and idiosyncratic responses across views.

This study investigates patient-clinician interactions using hyperscanning fMRI, finding that analgesia is mediated by behavioral mirroring and brain-to-brain concordance in social circuits, particularly in dyads with prior clinical rapport.

This paper uses crowdsourced EEG data from face-to-face interactions to show that brain synchrony correlates with empathy, social closeness, and engagement during naturalistic social behavior.

This study shows that disrupting the left inferior parietal lobule impairs the ability to infer intentions from movement kinematics, while leaving kinematic discrimination unaffected.

This study uses a 3-person fMRI hyperscanning paradigm to identify neural correlates of collaboration, finding increased activation and synchrony in theory of mind-related brain regions during a triadic task.

The paper investigates how movement initiation and grasp representation are encoded in premotor and primary motor cortex neurons during execution, observation, and withholding of reach-to-grasp actions in macaques.

The paper investigates how the visual cortex organizes representations of human actions by identifying five networks related to social aspects and interaction envelope scale.

This study investigates whether detecting social interactions is a rapid perceptual process or a slower post-perceptual inference using MEG decoding and computational modeling.

This paper investigates how weight expectations during object lifting observation modulate motor resonance, showing that pSTS suppression of motor resonance is critical for weight-based corticospinal excitability.

This study investigates whether mirror neuron-like activity exists in the mouse parieto-frontal network during action performance and observation, finding no overlap in neural responses.

This paper develops a computational model to explain how the brain arbitrates between imitation and emulation strategies in observational learning, supported by fMRI data showing specific brain regions involved in this process.

The paper introduces a novel point-light display dataset (SoPID) for studying social cognitive processes, showing high recognizability of communicative interactions.

This study uses HD-tDCS to show that the rTPJ causally influences embodied perspective taking, but not perspective tracking, by modulating the effect of body posture.

This paper investigates developmental changes in neural responses to social interactions in the pSTS and adjacent regions, finding increased selectivity and bilateral activation in adults compared to children.

The paper investigates how hippocampal-neocortical pattern similarity and connectivity contribute to pain empathy using fMRI data from human participants.

The paper investigates whether testosterone affects neural responses to observing others in pain and finds no effect on the pain matrix activation patterns.
