神经生理学和成像研究表明，看到其他人的动作会引起参与执行相同动作的运动区域的替代激活。虽然这表明一种模拟机制介导了对他人行为的感知，但人们不能使用这些证据来推断替代激活的功能意义。事实上，社会神经科学的一个中心目标是理解替代激活如何让人们理解他人的行为，这需要使用刺激或损伤方法来建立从大脑活动到认知功能的因果关系。在目前的工作中，我们回顾研究调查的影响，短暂的操纵大脑活动或稳定病变的运动系统对个人的能力，感知和理解他人的行动。我们的结论是，现在有令人信服的证据表明，运动系统中的神经活动对这种认知能力至关重要。然而，需要更多使用因果方法的研究，以揭示在感知和理解他人的行为以及他们的情绪和身体感受时，需要替代激活的限制和条件。
Neurophysiological and imaging studies have shown that seeing the actions of other individuals brings about the vicarious activation of motor regions involved in performing the same actions. While this suggests a simulative mechanism mediating the perception of others' actions, one cannot use such evidence to make inferences about the functional significance of vicarious activations. Indeed, a central aim in social neuroscience is to comprehend how vicarious activations allow the understanding of other people's behavior, and this requires to use stimulation or lesion methods to establish causal links from brain activity to cognitive functions. In the present work, we review studies investigating the effects of transient manipulations of brain activity or stable lesions in the motor system on individuals' ability to perceive and understand the actions of others. We conclude there is now compelling evidence that neural activity in the motor system is critical for such cognitive ability. More research using causal methods, however, is needed in order to disclose the limits and the conditions under which vicarious activations are required to perceive and understand actions of others as well as their emotions and somatic feelings.
