Emotional mimicry is defined as the tendency to imitate emotional expression of another people, which is more restricted by the social relational context than behavior imitation. Based on the perception-behavior link, the Motor Match Hypothesis proposed that Mirror Neuron System (MNS) is the core mechanism of emotional mimicry. However, more and more researchers argued that emotional mimicry is not a simple kind of behavioral imitation, proposing the Emotion Mimicry in Context View, emphasizing on the importance of social context, such as the relationship between actor and observer. What important is the activation of the MNS alone is not sufficient to explain the social dimension of facial mimicry. In addition to neural activation in brain regions attributed to the MNS, the multiple neuroimaging studies provided evidence for the activation of limbic system, motor system and brain regions involved in social evaluation and cognitive control processes. Meanwhile, emotional mimicry accepts the modulation by endocrine such as testosterone and oxytocin. Build upon previous studies, present research summarized the neural network involving in emotional mimicry and endocrine factors modulating the neural activity, introducing recent neuroendocrine models to show the neural pathway of emotional mimicry. Finally, studies in the future should provide support for neuroendocrine models and expand to the field of hyperscanning.
