In healthy people, motor resonance mechanisms are flexible to negative emotional contextual clues with greater motor resonance during the observation of a reach to grasp movement performed in an environment eliciting disgust. The link between emotion and motor control has become an interesting topic in Parkinson’s disease (PD). Here, we aimed to study the response of the mirror neuron system, specifically motor resonance, to an emotion-enriched context in people with PD. Corticospinal excitability was recorded in a total of 44 participants, divided into two groups (23 PD patients and 21 healthy subjects). We recorded motor-evoked potentials from a muscle involved in the grasping movement while participants were watching the same reach-to-grasp movement embedded in surrounds with negative emotional valence, but different levels of arousal: sadness (low arousal) and disgust (high arousal). Basic motor resonance mechanisms were less efficient in PD than controls. Responsiveness to emotional contextual clues eliciting sadness was similar between PD and controls, whereas responsiveness to emotional contextual clues eliciting disgust was impaired in PD patients. Our findings show reduced motor resonance flexibility to the disgusting context, supporting the hypothesis that PD patients may have a deficit in “translating” an aversive motivational state into a physiologic response. The amygdala, which is implicated in the appraisal of fearful stimuli and response to threatening situations, might be implicated in this process.

帕金森病患者情绪丰富背景下的运动共振灵活性

在健康人中,运动共振机制对负面情绪背景线索具有灵活性,在观察在引起厌恶的环境中进行的抓握运动时具有更大的运动共振。情绪和运动控制之间的联系已成为帕金森病 (PD) 中一个有趣的话题。在这里,我们的目的是研究镜像神经元系统的反应,特别是运动共振,对 PD 患者情绪丰富的环境的反应。共有 44 名参与者记录了皮质脊髓兴奋性,分为两组(23 名 PD 患者和 21 名健康受试者)。我们记录了参与抓握运动的肌肉的运动诱发电位,同时参与者正在观看嵌入在具有负面情绪效价但不同唤醒水平的环境中的相同的抓握运动:悲伤(低觉醒)和厌恶(高觉醒)。基本电机共振机制在 PD 中的效率低于控制。PD 和对照组对引发悲伤的情绪背景线索的反应相似,而 PD 患者对引发厌恶的情绪背景线索的反应受损。我们的研究结果表明,对于令人厌恶的环境,运动共振灵活性降低,支持 PD 患者可能无法将厌恶的动机状态“转化”为生理反应的假设。与恐惧刺激的评估和对威胁情况的反应有关的杏仁核可能与这个过程有关。PD 和对照组对引发悲伤的情绪背景线索的反应相似,而 PD 患者对引发厌恶的情绪背景线索的反应受损。我们的研究结果表明,对于令人厌恶的环境,运动共振灵活性降低,支持 PD 患者可能无法将厌恶的动机状态“转化”为生理反应的假设。与恐惧刺激的评估和对威胁情况的反应有关的杏仁核可能与这个过程有关。PD 和对照组对引发悲伤的情绪背景线索的反应相似,而 PD 患者对引发厌恶的情绪背景线索的反应受损。我们的研究结果表明,对于令人厌恶的环境,运动共振灵活性降低,支持 PD 患者可能无法将厌恶的动机状态“转化”为生理反应的假设。与恐惧刺激的评估和对威胁情况的反应有关的杏仁核可能与这个过程有关。支持 PD 患者可能无法将厌恶的动机状态“转化”为生理反应的假设。与恐惧刺激的评估和对威胁情况的反应有关的杏仁核可能与这个过程有关。支持 PD 患者可能无法将厌恶的动机状态“转化”为生理反应的假设。与恐惧刺激的评估和对威胁情况的反应有关的杏仁核可能与这个过程有关。
