Anterograde tracing with the carbocyanine dye, Di-I, was used to describe the normal postnatal development of the projection from the trigeminal (V) brainstem complex to the superior colliculus (SC) in hamster. In adult hamsters, this projection is completely restricted to the deep laminae, primarily the stratum album intermedium. Trigeminal fibers were present in the SC by the day of birth, and at this time, they terminated mainly in the deep layers. However, labelled fibers also extended into the superficial laminae (the stratum griseum superficiale and stratum opticum) reaching as far as the SC surface. Trigeminal projections to the superficial SC laminae were visible as late as postnatal day (P-) 6, but were absent by P-8. During the period when V axons were present in the superficial SC laminae, they could not be detected in the dorsal lateral geniculate nucleus.
运用羰花青染料Di-I进行顺行示踪，以描述仓鼠三叉神经（V）脑干复合体至中脑上丘（SC）投射的正常出生后发育情况。在成年仓鼠中，这种投射完全局限于深层，主要是中间白质层。三叉神经纤维在出生当天就已出现在上丘，此时它们主要终止于深层。然而，标记纤维也延伸至浅层（浅灰质层和视层），最远到达上丘表面。三叉神经至浅层上丘的投射最晚在出生后第（P-）6天可见，但在P-8时消失。在V轴突存在于浅层上丘的时期，在背外侧膝状核中无法检测到它们。
