Embryonic vertebrate central nervous system: Revised terminology
The layers and cells of the early developing central nervous system lack direct counterparts in the adult and must be designated by a special terminology. The inconsistent and inaccurate language nowExpand

Origin of the retina from both sides of the embryonic brain: a contribution to the problem of crossing at the optic chiasma.
Cells originating from one of the first two blastomeres of the frog embryo were labeled either by injecting them with horseradish peroxidase or by changing the ploidy of one blastomere. Both methodsExpand

δ‐catenin is a nervous system‐specific adherens junction protein which undergoes dynamic relocalization during development
δ‐catenin is a member of the Armadillo repeat family and component of the adherens junction discovered in a two‐hybrid assay as a bona fide interactor with presenilin‐1 (Zhou et al., [ 1997 ],Expand

Neurite outgrowth traced by means of horseradish peroxidase inherited from neuronal ancestral cells in frog embryos.
Outgrowing neurites in Xenopus embryos were labeled with horseradish peroxidase which had been injected into a single blastomere at the 32-cell stage and had been inherited by all the descendants,Expand

Using metal-filled micropipette electrodes we have recorded responses from single units in the optic tectum and optic chiasma of the goldfish. Responses were evoked by visual stimulation with spotsExpand

Induction of neural cell adhesion molecule (NCAM) in Xenopus embryos.
Using a classical neural induction protocol (H. Spemann and H. Mangold (1924). Roux' Arch. Entwicklungsmech. Org. 123, 389-517), it has been demonstrated that the sustained presence of NCAM inExpand

Postnatal changes in arborization patterns of murine retinocollicular axons
The growth and arborization of murine retinocollicular axons have been studied by means of HRP axon filling during postnatal development. Transformations in arborization patterns have been correlatedExpand

Histogenesis and Morphogenesis of Cortical Structures
Three important theories of nervous organization, valid for our time , emerged from the cell theory. Firstly, the demonstration that the nerve cell and fiber are parts of the same structure (firstExpand

Patterns of cell proliferation in the retina of the clawed frog during development
Quantitative assays of the spatial pattern of cell production in the developing retina of Xenopus have been made using 3H‐thymidine labelling and colcemid blockade of mitosis. Reconstructions wereExpand

Clonal organization of the central nervous system of the frog. I. Clones stemming from individual blastomeres of the 16-cell and earlier stages.
Horseradish peroxidase injected into individual blastomeres of 2- to 16-cell embryos of Xenopus laevis can later be identified in cells at larval stages 31 to 37. The label is confined to the progenyExpand
