| Abstract(in English) | Birds have a well-developed centrifugal pathway from the optic tectum to the retina via the isthmo-optic nucleus (ION). We examined functional and morphological properties of the retinopetal system. The avian retinopetal system is a neural structure that is composed of parallel 10,000 retinopetal modules, which, in turn, are composed of three serially connected neurons (tecto-IO neurons, IO neurons and IO target cells in the retina). The retinopetal modules compete each other in a long range scale. IO-lesioned animals showed delay in pecking time to scattered foods. These results may support a hypothesis that the retinopetal system plays some role in synthesis of visual focal attention. |
