| Research Abstract |
To know how the visual organizations of bird and mammal have been developed from the amphibian, the following matters have been studied in the bird (chick) and amphibian (frog). 1) The sublaminar structures of the IPL and its immunoreactivity to calcium-binding-protein and GAD in the avian retina. 2) The appearance rate and distribution of the double-labeled RGCs projecting to both tectum and thalamus in birds. 3) Feature of the dendritic arborization of the nAChRβ2-immunoreactive RGCs projecting to the tectal layer F. 4) Size and distribution-density of the frog RGCs. 5) Morphological differences in the retinal receptive layers between the avian and mammalian tectum. 6) Behavioral reaction to the wavelength and brightness in the frog.
