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.
