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

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.
