Roe and his colleagues (1990)caused the developing axons of ferret retinal ganglion cells to synapse in the medial geniculate nuclei of the auditory system.Once the ferrets matured, their

Embryonic cells that have the potential for unlimited renewal and have the ability to develop into different kinds of mature cells if they are transplanted to different sites are often called

Considering their mental retardation, people with Williams syndrome tend to have remarkably good

A recent finding is that synaptogenesis depends on the presence of

In support of the topographic-gradient hypothesis, it has been shown that

In mammals, adult neurogenesis occurs in the

In frogs, salamanders, and other simple vertebrates, retinal ganglion cells project primarily to the
