达尔文将情绪视为适应性行为的倾向，从而表明特征性的身体运动与每种情绪状态相关。迄今为止，情绪认知的研究主要集中在与观看面部表情相关的过程上。然而，富有表现力的身体动作对于理解情绪行为的神经生物学可能同样重要。在这里，我们使用功能性 MRI 来阐明大脑如何识别整个身体表达的快乐或恐惧。我们的结果表明，观察恐惧的身体表情会导致与情绪过程密切相关的大脑区域活动增加，并且这种与情绪相关的活动与与动作和运动表征相关的区域的激活同时发生。在此提出的恐惧传染机制可能会自动让大脑做好采取行动的准备。
Darwin regarded emotions as predispositions to act adaptively, thereby suggesting that characteristic body movements are associated with each emotional state. To this date, investigations of emotional cognition have predominantly concentrated on processes associated with viewing facial expressions. However, expressive body movements may be just as important for understanding the neurobiology of emotional behavior. Here, we used functional MRI to clarify how the brain recognizes happiness or fear expressed by a whole body. Our results indicate that observing fearful body expressions produces increased activity in brain areas narrowly associated with emotional processes and that this emotion-related activity occurs together with activation of areas linked with representation of action and movement. The mechanism of fear contagion hereby suggested may automatically prepare the brain for action.
