Functional near-infrared spectroscopy and behavioural methods were used to examine the neural basis of the behavioural contagion and authenticity of laughter. We demonstrate that the processing of laughter sounds recruits networks previously shown to be related to empathy and auditory-motor mirror networks. Additionally, we found that the differences in the levels of activation in response to volitional and spontaneous laughter could predict an individual's perception of how contagious they found the laughter to be.

SMA 前激活以及对笑声中传染性和真实性的感知

功能性近红外光谱和行为方法用于检查行为传染的神经基础和笑声的真实性。我们证明了笑声的处理会招募先前显示与移情和听觉运动镜像网络相关的网络。此外，我们发现对自主和自发笑声的反应激活水平的差异可以预测个人对他们发现笑声的传染性的感知。
