将我们对大脑功能的基本认识转化为实际电子模型的例子很少。在这里，我们提出了一个用户友好的硅模型的早期视觉系统，有助于动物福利。硅芯片通过使用模拟超大规模集成电路（VLSI）来模拟视觉系统中的神经元。它在实验设计和演示中代替了活的动物。这个芯片上的神经元显示出生物视觉的核心特性：感受野、尖峰编码、适应、带通滤波和互补信号。与以前的实验室设备不同，其复杂性受到印刷电路板上使用分立元件的限制，这种电池供电的芯片是视觉系统的独立补丁。芯片的细胞和自我包含的调整免费正确的操作的芯片的现实的反应建议的可能性，实施类似的电路的视觉假体。(C)2004爱思唯尔有限公司保留所有权利。
Examples that show the transfer of our basic knowledge of brain function into practical electronic models are rare. Here we present a user-friendly silicon model of the early visual system that contributes to animal welfare. The silicon chip emulates the neurons in the visual system by using analog Very Large Scale Integration (aVLSI) circuits. It substitutes for a live animal in experiment design and lecture demonstrations. The neurons on this chip display properties that are central to biological vision: receptive fields, spike coding, adaptation, band-pass filtering, and complementary signaling. Unlike previous laboratory devices whose complexity was limited by the use of discrete components on printed circuit boards, this battery-powered chip is a self-contained patch of the visual system. The realistic responses of the chip's cells and the self-contained adjustment-free correct operation of the chip suggest the possibility of implementation of similar circuits for visual prosthetics.
