Abstract：The outer plexiform layer of the frog retina was taken as a three dimensional system, of which the input was illuminance on the frog retina, and the output was receptor potential transmitted to the lower level system by bipolar cells. The pattern of this system's information processing was supposed to be that besides transmitting one nerve signal directly to bipolar cells, photosensory cells would transmit another nerve signal to horizontal cells, which would be transmitted to all directions in the horizontal cells forming an accepting region of disk shape, then be transmitted to the bipolar cells becoming inhibitory signals, while the strength of which would go into exponential decay with the disk area increasing. The two signals would go into exponential decay with time when they are brought into the bipolar cells. In accordance with the pattern, a mathematical model was established, and a point impulse response of caused by illuminance of was acquired. According to the result of Fourier analysis, it was confirmed that the model corresponded with the feature detectors of the frog eye in spatial filtering.
