It is well known that visual information is continuously transformed into spike discharges in ganglion cells in the retinal circuits. However, little is known about the visual features encoded in the spike patterns and corresponding fundamental circuit structures of the retina. In order to elucidate the issue, previous studies have recorded and analyzed responses of retinal ganglion cells to randomly modulated illumination mainly from the statistical point of view. In this study, we designed an integrated circuit system that mimics the fundamental structure of retinal circuit and reproduced the ganglion cell responses to elucidate the dynamical properties of signal coding. We implemented the transient tOff-$alpha$ganglion cell circuit and simulated the spike responses evoked by randomly modulated illumination. The model exhibited spike responses including intermittent high frequency spike sequences similar to the physiologically recorded responses. Using the model, spike patterns were shown to be classified in terms of inter-spike intervals. The model designed in the present study is useful to efficient study the visual function and relevant fundamental circuit structures in the natural visual environment. |
