The observation of other's behaviour results in increased corticospinal excitability (CSE) within the primary motor cortex, a phenomenon that has typically been interpreted in the context of motor resonance and human "mirror systems". Mirror systems are implicated in empathy, and may therefore show a preferential response to the observation of interactive behaviour. Participants were administered transcranial magnetic stimulation (TMS) to the primary motor cortex while viewing matched hand movements with or without (1) an interactive context and (2) an interactive context with an implied heightened emotional aspect. CSE was not enhanced when viewing interactive (compared with individual) hand movements. There was, however, some evidence for an enhanced response when viewing hand movements with an emotional component. There was no association between mirror systems and self-reported empathy. Mirror systems may not be more responsive to interactive behaviour, but the inclusion of a strong emotional element could be of significance to mirror neurons.
观察他人的行为会导致初级运动皮层中的皮质脊髓兴奋性（CSE）增加，这种现象通常被解释为运动共振和人类“镜像系统”的作用。镜像系统与同理心有关，因此可能会对观察互动行为表现出优先反应。参与者在观看匹配的手运动时接受经颅磁刺激（TMS），这些手运动具有或不具有（1）互动背景和（2）具有隐含增强的情感方面的互动背景。当观看互动（与单独）手运动时，CSE 并没有增强。然而，当观看具有情感成分的手运动时，有一些证据表明反应增强。镜像系统与自我报告的同理心之间没有关联。镜像系统可能对互动行为的反应不那么敏感，但包含强烈的情感元素可能对镜像神经元具有重要意义。
