In the rat's ventral lateral geniculate nucleus (vLGN), geniculo-tectal relay neurons (GTR-neurons) could be identified by the retrograde transport of horseradish peroxidase (HRP) after injection in the superior colliculus (SC). GTR-neurons correspond to class III cells described by Brauer and Schober (1973) in Golgi preparations of the rat's LGN. The distribution of GTR-neurons is restricted to the lateral subnucleus of vLGN. According to Swanson et al. (1974), the axons of these cells terminate in lower Stratum griseum superficiale and in Stratum opticum, Stratum griseum intermedium and Stratum album intermedium of SC. The GTR-neurons are characterized by very thick and long proximal dendritic segments which have a smooth surface. Dendrites branch preponderantly in their distal regions and only in this part form many multiform protrusions. There is some evidence that retinal axons terminate on these dendritic surface structures. The supposed differences in the afferent patterns between GTR-neurons in the vLGN and geniculo-cortical relay neurons in the dorsal lateral geniculate nucleus are discussed.
在大鼠的腹侧外侧膝状核（vLGN）中，通过将辣根过氧化物酶（HRP）注射到上丘（SC）后进行逆行运输，可以识别出膝状体 - 顶盖中继神经元（GTR神经元）。GTR神经元对应于Brauer和Schober（1973年）在大鼠外侧膝状核的高尔基制剂中描述的III类细胞。GTR神经元的分布局限于vLGN的外侧亚核。根据Swanson等人（1974年）的研究，这些细胞的轴突终止于SC的浅层灰质下部以及视神经层、中间灰质层和中间白质层。GTR神经元的特征是近端树突段非常粗大且长，表面光滑。树突主要在其远端区域分支，并且仅在这部分形成许多多样的突起。有证据表明视网膜轴突终止于这些树突表面结构。本文讨论了vLGN中GTR神经元与背侧外侧膝状核中膝状体 - 皮质中继神经元传入模式的假定差异。
