Research Abstract |
In lower vertebrates, optic tectum is the visual center and receives retinal fibers in a retinotopic manner. We have shown that Ephrin A2 and A5, which are expressed in the posterior tectum and repel temporal retinal fibers, are induced by Fgf8, but that signal transduction to induce Ephrin A2 and A5 are different. We have elaborated new fiber tracing method, and unraveled new but transient retinotectal pathway which invade deeper layer of the tectum from the first.
