[Transfer of behavior patterns through transplantation of systems of neuroanatomic structures in amphibian larvae. II. Xenoplastic transplantation of hind brain systems between Xenopus laevis (Daud.) as well as Hymenochirus boettgeri (Torn.) and Triturus vulgaris].

By replacing parts of the neural plate (prospective medulla oblongata) of Triturus vulgaris by neural ectoderm of Xenopus laevis larval chimaeras were obtained, which showed donorlike rhythmical movements of distinct parts of the visceral musculature according to the place of implantation. Especially the branchial region with its external gills showed rhythmical movements and is the special object of this investigation.
