自闭症的“破镜”理论认为，“镜像神经元系统”的功能障碍是自闭症社交障碍的根本原因。本文旨在仔细研究这一理论，并在它崩溃时提供一种替代方案。目前的证据表明，自闭症儿童能够理解和模仿目标导向的行动，但可能在无目标的自动模仿行动方面有特定的障碍。这些数据与破镜理论不相容，但可以用一种称为EP-M的新模型来解释。EP-M模型将镜像神经元系统分割为用于目标仿真和规划（EP）的间接顶叶路线和用于模仿（M）的直接枕额路线。这种分离与典型儿童和成人镜像神经元系统的神经影像学和行为学研究一致。我认为，自上而下的调制的直接M路线可能是功能失调的自闭症患者，导致异常行为的模仿任务以及其他社会残疾。
The "broken-mirror" theory of autism argues that dysfunction of the "mirror neuron system" is a root cause of social disability in autism. The present paper aims to scrutinize this theory and, when it breaks down, to provide an alternative. Current evidence suggests that children with autism are able to understand and emulate goal-directed actions, but may have specific impairments in automatic mimicry of actions without goals. These data are not compatible with the broken-mirror theory, but can be accounted for by a new model called EP-M. The EP-M model segments the mirror neuron system into an indirect, parietal route for goal emulation and planning (EP) and a direct occipital-frontal route for mimicry (M). This fractionation is consistent with neuroimaging and behavioural studies of the mirror neuron system in typical children and adults. I suggest that top-down modulation of the direct M route may be dysfunctional in individuals with autism, leading to abnormal behaviours on mimicry tasks as well as other social disabilities.
