疼痛与参与观察学习和模仿的行动系统密切相关。对自身疼痛的运动反应允许冻结或逃避反应，并最终生存。在这里，我们表明，类似的运动反应发生的结果，观察痛苦的事件在其他人。我们使用经颅磁刺激来记录观察针穿透人体模型或非correlative对象的手或脚的个体的手部肌肉的皮质脊髓运动表征的变化。我们发现运动诱发电位的振幅降低，这是受试者观察到被刺伤的肌肉所特有的。这种抑制与观察者的主观评价的感官素质的疼痛归因于模型和感官，但不是情感，状态或特质的共情措施。对他人疼痛的感觉品质的移情推理及其在观察者运动系统中的自动体现可能对疼痛反应的社会学习至关重要。
Pain is intimately linked with action systems that are involved in observational learning and imitation. Motor responses to one's own pain allow freezing or escape reactions and ultimately survival. Here we show that similar motor responses occur as a result of observation of painful events in others. We used transcranial magnetic stimulation to record changes in corticospinal motor representations of hand muscles of individuals observing needles penetrating hands or feet of a human model or noncorporeal objects. We found a reduction in amplitude of motor-evoked potentials that was specific to the muscle that subjects observed being pricked. This inhibition correlated with the observer's subjective rating of the sensory qualities of the pain attributed to the model and with sensory, but not emotional, state or trait empathy measures. The empathic inference about the sensory qualities of others' pain and their automatic embodiment in the observer's motor system may be crucial for the social learning of reactions to pain.
