A patient with the volitional type of facial palsy showed in the arteriography an obstruction of the middle cerebral artery without affecting the thalamostriatal arteries. As laughing and weeping are motivated in the cerebral trunc they must have been projected through the mesopallium (which includes the thalamus) to the facial nuclei. These two behaviour elements did not show any modification on the paretic side, indicating so, that they are phylogenetic old elements, normally modified by the volitional influence. The original weeping expresses an appeal to the companion, the original laughing the readiness of affilation.
一名患有意志性面瘫的患者在动脉造影中显示大脑中动脉阻塞，但未影响丘脑纹状体动脉。由于哭笑是由脑干激发的，它们一定是通过中脑皮质（包括丘脑）投射到面神经核的。这两种行为元素在患侧没有任何改变，这表明它们是系统发育上古老的元素，通常受意志影响而改变。原始的哭泣表达了对同伴的诉求，原始的笑则表示愿意亲近。
