Studies in the development of frog hybrids III Inductive ability of the dorsal lip region of Rana pipiens female x Rana sylvatica male hybrids

, : Studies in the development of frog hybrids III Inductive ability of the dorsal lip region of Rana pipiens female x Rana sylvatica male hybrids. Jour Exptl Zool: 127-153

The cessation of normal development at the beginning of gastrulation in the R. pipiens female x R. sylvatica male hybrids is associated with a reduction in potency of the dorsal lip organizer. This is shown by the fact that the structures formed in the secondary embryo following implantation of a hybrid dorsal lip into the blastocoel of a normal embryo are small in size, less frequent in occurrence, and poorer in degree of differentiation than are those formed through the action of a normal dorsal lip.

Most stroke survivors exhibit a partial recovery from their deficits. This presumably occurs because of remapping of lost capabilities to functionally related brain areas. Functional brain imaging studies suggest that remapping in the contralatera...
