Abstract:
Young frogs, Xenopus laevis, raised on a white background showed a slight preference for the black background of a black-white preference testing apparatus. Keeping frogs for either 24 hr or 20 days on a black background resulted in a further increase in their preference for black. Injecting 1 μg of synthetic α-MSH into white-adapted frogs had no effect on their black-white preference. On the other hand, Xenopus laevis tadpoles, at an early stage of metamorphosis, raised on a white background showed a significant preference for white. Keeping these tadpoles for 24 hr on a black background resulted in a shift from white to black preference. Injecting synthetic α-MSH into white-adapted tadpoles resulted in an increase in their preference for black. A behavioral feedback mechanism appears to exist between the release of endogenous MSH when a tadpole is exposed to a black background and its subsequent preference for background color. © 1978.
