The purpose of this study is to examine the correlation between the morphological characteristics and spectral responses of horizontal cells in black bass retina. Three layers of horizontal cell bodies and one layer of fine processes of horizontal cell axons were recognized in the horizontal cell layer. The most distally layered H1 cells were smaller than the H2 cells which form the second layer. Both H1 and H2 cells showed a monophasic spectral response with a maximum peak for red light. In the third layer, two kinds of horizontal cells, H3 and H4, were recognized. These horizontal cells were characterized by a similar morphology of their thinner and longer primary processes, but the staining of one type of horizontal cell was lighter than that of the other. Horizontal cells from the third layer showed biphasic spectral responses, which hyperpolarized to green light and depolarized to red light, although a question of which type of horizontal cells, H3 or H4, showed the biphasic spectral response was not clarified. Proximal to the third layer, a mesh-like profile of fine axon processes of horizontal cells was observed.
