A dissociation between voluntary and emotional facial innervation is described in a patient with a pure motor stroke due to a unilateral ischaemic pontine infarction. Voluntary facial innervation of the contralateral orbicularis oris muscle was affected whereas emotionally induced innervation of the same muscle was spared. This report provides evidence that fibres conveying voluntary and emotional commands are still separated in the pons. Whereas corticobulbar tracts carry the information for voluntary facial innervation, efferents from the amygdala and the lateral hypothalamus are candidates for the somatomotor aspects of emotions.
一名因单侧缺血性脑桥梗死导致纯运动性卒中的患者，其面部随意性和情感性神经支配之间存在分离现象。对侧口轮匝肌的面部随意性神经支配受到影响，而同一肌肉的情感诱导性神经支配未受影响。本报告提供了证据，表明在脑桥中传递随意性和情感性指令的纤维仍然是分开的。皮质延髓束携带面部随意性神经支配的信息，而杏仁核和下丘脑外侧的传出纤维是情感躯体运动方面的候选者。
