Different parts of our brain code the perceptual features and actions related to an object, causing a binding problem, in which the brain has to integrate information related to an event without any interference regarding the features and actions involved in other concurrently processed events. Using a paradigm similar to Hommel, who revealed perception-action bindings, we showed that emotion could bind with motor actions when relevant, and in specific conditions, irrelevant for the task. By adapting our protocol to a functional Magnetic Resonance Imaging paradigm we investigated, in the present study, the neural bases of the emotion-action binding with task-relevant angry faces. Our results showed that emotion bound with motor responses. This integration revealed increased activity in distributed brain areas involved in: (i) memory, including the hippocampi; (ii) motor actions with the precentral gyri; (iii) and emotion processing with the insula. Interestingly, increased activations in the cingulate gyri and putamen, highlighted their potential key role in the emotion-action binding, due to their involvement in emotion processing, motor actions, and memory. The present study confirmed our previous results and point out for the first time the functional brain activity related to the emotion-action association.
大脑的不同部位对与物体相关的感知特征和动作进行编码，从而产生绑定问题，即大脑必须整合与事件相关的信息，而不受其他同时处理的事件中涉及的特征和动作的干扰。我们使用类似于 Hommel 的范式，揭示了感知-动作绑定，表明当相关时，情绪可以与运动动作绑定，并且在特定条件下，与任务无关。通过将我们的方案适应功能磁共振成像范式，我们在本研究中研究了与任务相关的愤怒面孔的情绪-动作绑定的神经基础。我们的结果表明，情绪与运动反应绑定。这种整合揭示了与记忆相关的大脑区域（包括海马体）、与运动动作相关的大脑区域（中央前回）和与情绪处理相关的大脑区域（脑岛）的活动增加。有趣的是，扣带回和壳核的激活增加，突出了它们在情绪-动作绑定中的潜在关键作用，因为它们涉及情绪处理、运动动作和记忆。本研究证实了我们之前的结果，并首次指出了与情绪-动作关联相关的大脑功能活动。
