[Transfer of behavior patterns through transplantation of anlagen of neuro-anatomic structures in amphibian larva. 1. Xenoplastic exchange of medulla anlagen between Xenopus laevis and Hymenochirus boettgeri (Amphibia, Anura)].
By transplantation of parts of the neural plate (latter medulla oblongata) from Xenopus laevis (Daud.) to Hymenochirus boettgeri (Torn.) larval chimaeras were obtained, which showed donorlike rhythmical movements of the mouth and pharyngeal region, movements which the host species lacks. Nevertheless, some of these tadpoles were still able to catch small prey in a reaction which is typical for the host and lacking in the donor.
