Carp Responses of Color Coded Ganglion Cells Evoked by Current Injection into Horizontal Cells
In catfish and dogfish retina where a single receptor type determines the light response, the projections from horizontal cells (h.c.s) to ganglion cells (g.c.s) are all sign inverting. Injection of a hyperpolarizing current into the h.c. results in a g.c. response of equal sign as the g.c. surround response, whereas a depolarizing current results in a response of the center sign (Naka & Nye, 1971; Naka & Witkovsky, 1972; Naka, 1976). In pike retina and in turtle retina also On/Off g.c. responses to extrinsic current injected into h.c.s have been described (Maksimova, 1969; Schwartz, 1973); while in carp retina an even more complex response behavior is observed.
