我们最近开发了一种以 5 毫秒的帧间隔运行的视网膜形态硬件系统，该系统足够短，可以以准连续的方式模拟视网膜电路中神经元的分级电压响应。目前，我们取得了进一步的进展，通过实现 Izhikevich 模型，可以以毫秒级计时精度模拟神经节细胞层中的空间尖峰分布。该系统对于检查自然视觉场景的视网膜尖峰编码非常有用。
We recently developed a retino-morphic hardware system operating at a frame interval of 5 ms, that was short enough for simulating the graded voltage responses of neurons in the retinal circuit in a quasi-continuous manner. In the present, we made a further progress, by implementing the Izhikevich model so that spatial spike distributions in a ganglion-cell layer can be simulated with millisecond-order timing precision. This system is useful for examining the retinal spike encoding of natural visual scenes.
