Early development of dorsal column-medial lemniscal projections in the clawed toad, Xenopus laevis.
In Xenopus laevis fluorescent dextran amines were applied to study the development of the dorsal column-medial lemniscal projection: rhodamine dextran amine was applied at the mesodiencephalic border to retrogradely label the cells of origin of the medial lemniscus in the dorsal column nucleus (DCN); fluorescein dextran amine to the spinal cord to anterogradely label the primary afferent projections to the DCN. The first mesodiencephalic projections were found at stage 51, i.e. almost immediately after spinal afferent fibers had reached the DCN.
