Following stereotaxic injections of horseradish peroxidase in the dorsal thalamus of the cat which were restricted to the lateralis posterior-pulvinar complex, labelled neurons were found in the superficial layers of the superior colliculus and in the brainstem. The retrogradely-filled cells of the brainstem were situated principally in the nucleus tegmenti pedunculopontinus, the locus coeruleus complex, the parabrachial nuclei and the dorsal tegmental nucleus of Gudden; in each case, labelled cells were more numerous on the ipsilateral side. In addition, some scattered neurons were observed in the central grey matter, the mesencephalic reticular formation, the central superior and dorsal raphe nuclei, the cuneiform nucleus reticularis gigantocellularis, the nucleus praepositus hypoglossi and the oculomotor nuclei. The differential organization of these projections were observed. It is concluded that the rostrointermediate subdivision of the lateralis posterior-pulvinar complex receives most of its connections from the nucleus tegmenti pedunculopontinus, from the deep layers of the superior colliculus and from the other brainstem nuclei, while the caudal subdivision (extrageniculate visual subdivision) receives its main projection from the superficial layers of the superior colliculus. The findings may have functional implications for the role of the complex in oculomotor control.
在猫的背侧丘脑进行立体定向辣根过氧化物酶注射，将其限制在丘脑后外侧-丘脑枕复合体，结果发现在上丘浅层和脑干中有标记神经元。脑干中逆行填充的细胞主要位于脚桥被盖核、蓝斑复合体、臂旁核和古登背侧被盖核；在每种情况下，同侧标记细胞数量更多。此外，在中央灰质、中脑网状结构、中央上核和背侧中缝核、楔形巨细胞核、舌下前置核和动眼神经核中观察到一些散在的神经元。观察到这些投射的差异组织。得出的结论是，丘脑后外侧-丘脑枕复合体的嘴侧中间亚区的大部分连接来自脚桥被盖核、上丘深层和其他脑干核，而尾侧亚区（外侧膝状体视觉亚区）的主要投射来自上丘浅层。这些发现可能对该复合体在眼球运动控制中的作用具有功能意义。
