This paper introduces an adaptive aberration correction method for transcranial ultrasound Doppler imaging, improving image quality in rats by accounting for skull-induced wave refraction.

This paper introduces a behavior-informed modeling framework to account for motion-related confounds in functional ultrasound imaging during naturalistic behaviors in awake mice.

This study examines how early and adolescent adversity differently affect emotional contagion in rats, finding distinct effects on observer-to-demonstrator and demonstrator-to-observer emotional transfer, with sex-specific pathways.

This paper develops ultrasound-transparent neural interfaces that enable compatibility with functional ultrasound imaging and therapy, validated through simulations and experiments.

This study investigates positive emotional contagion in juvenile rats through play observation, finding increased play behavior after observing playful demonstrators without 22 kHz calls.

The paper investigates how brain regions encode emotional facial expressions using representational similarity analysis, finding that vmPFC and mid-posterior insula encode emotion categories and arousal+valence better than arousal alone.

Selective-plane functional ultrasound neuroimaging enables high-resolution, low-computational brain activity monitoring by targeting specific brain regions without moving the probe.

This paper introduces nonlinear sound-sheet microscopy to image opaque organs at the capillary and cellular scale, achieving faster imaging speed, larger volume, and higher resolution than existing biomolecular ultrasound techniques.

The paper introduces an acoustic pH sensor called pHonon for deep tissue imaging of cellular acidification using nonlinear ultrasound.

The paper investigates how the endogenous opioid receptor system influences altruistic costly helping by linking MOR availability to brain activity during vicarious pain and helping behavior.

The paper examines how mirror-pain synesthetes and non-synesthetes differ in their willingness to help others in pain, using fMRI to link brain activity to donation decisions across different pain-conveying modalities.

The paper develops a Brain Reward Signature (BRS) using a LASSO-PCR model to predict reward and loss processing from brain activity, achieving high decoding accuracy across multiple tasks and samples.

The paper uses ECoG to study how the action observation network integrates information during action observation, finding top-down beta and bottom-up gamma oscillations in predictable and unpredictable actions respectively.

The paper uses intracranial recordings to show that the insula encodes pain intensity from different stimuli with distinct spatial and temporal coding patterns.

This paper investigates how commanding or acting as an intermediary affects moral behavior and brain mechanisms, finding no difference in agency between commanders and intermediaries but a neural response difference when agents are robots versus humans.

The paper uses intersubject functional correlation with 7T fMRI to show that predictable action sequences trigger more feedback input to parietal regions than unpredictable ones.

The paper shows that obeying orders reduces vicarious brain activation related to others' pain and decreases feelings of guilt and responsibility.

This paper evaluates parametric tests for leave-one-out inter-subject correlations in fMRI, showing they control Type I error and are sensitive for detecting neural synchronization.

The paper investigates action-outcome learning in moral conflicts using reinforcement learning models and fMRI, finding that model-based learning explains choices and reveals neural biases in valuing self-gain versus other-pain.

This study shows that MB4 acceleration improves single-subject voxel-wise statistics in fMRI, with moderate effect sizes in the action observation network, but may over-penalize temporal autocorrelation.

This study uses Bayesian analysis to show that a new HD-tDCS protocol does not reliably modulate somatosensory cortex excitability across participants.

The paper demonstrates that rats exhibit harm aversion when choosing a lever that harms another rat, with anterior cingulate cortex involvement.

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 evaluates if higher multiband (MB) acceleration improves BOLD signal detection in cognitive tasks, finding MB4 provides better group-level results than lower acceleration.

This paper introduces intersubject correlation analysis to measure shared neural responses across subjects in naturalistic scenarios.

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.

This study shows that rats exhibit bidirectional distress transmission regardless of familiarity, with cingulate-dependent mechanisms influencing both observer and demonstrator behavior.

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.
