The somatotopic organization of the human cerebellum processes somato-motoric input. Its role during pain perception for nociceptive input remains ambiguous. A standardized experimental trigeminal nociceptive input in functional imaging might clarify the role of the cerebellum in trigeminal nociception. Also of interest is the greater occipital nerve, which innervates the back of the head, and can influence the trigeminal perception due to functional coupling within the brainstem, forming the so-called trigemino-cervical complex.

伤害感受期间三叉神经-颈复合体的小脑体型

人类小脑的躯体组织处理躯体运动输入。它在伤害性输入的疼痛感知过程中的作用仍然不明确。功能成像中标准化的实验性三叉神经伤害感受输入可能会阐明小脑在三叉神经伤害感受中的作用。同样令人感兴趣的是枕大神经，它支配后脑勺，并且由于脑干内的功能耦合可以影响三叉神经的感知，形成所谓的三叉神经-颈复合体。
