Abstract

Work begun on this project last summer revealed that grafts of the hypothalamus from embryos and albino larvae of the salamander, Ambystoma tigrinum melanostictum caused melanin dispersion to occur in the melanophores of larval albino hosts of the same species. This summer a similar study has been extended to the adult. Various areas of the brain of hypophysectomized adult salamanders have been transplanted to albino larvae to determine the specific source of this melanophore-stimulating substance reported earlier. Project Number 122.
