Abstract(in English) Spectral responses from horizontal cells in the goldfish retina were recorded, and a mathematical model that accounts for the steady state properties of color opponent signals in these cells was developed. On the other hand, in order to analyze spatial information of the retina, it is necessary to obtain multi-site ERG responses from retinal surface as well as intra-retinal layers. For three-dimensional ERG recording, here we developed a multi-channel electrode array consisting of both penetrating microprobes and planar microelectrodes. We conclude that the penetrating probes of various lengths and planar electrode in an array are useful for the detection of subtle changes between the surface and intra-retinal ERGs. The multi-channel and simultaneous recording of the surface and intra-retinal ERGs would be important for further investigation of visual information processing in the retina.
