通过将神经生理学原理与硅工程相结合，我们生产出了具有真实神经细胞功能特征的模拟集成电路。由于硅器件和生物膜的导电性背后的物理原理相似，因此“硅神经元”能够有效地模拟引起神经冲动的离子电流并控制其放电动力学。它实时运行且功耗极低，并且可以在单个硅芯片上制造许多“神经元”。硅神经元代表了构建人工神经系统的一步，该系统使用比现有电子神经网络更现实的神经计算原理。
BY combining neurophysiological principles with silicon engineering, we have produced an analog integrated circuit with the functional characteristics of real nerve cells. Because the physics underlying the conductivity of silicon devices and biological membranes is similar, the 'silicon neuron' is able to emulate efficiently the ion currents that cause nerve impulses and control the dynamics of their discharge. It operates in real-time and consumes little power, and many 'neurons' can be fabricated on a single silicon chip. The silicon neuron represents a step towards constructing artificial nervous systems that use more realistic principles of neural computation than do existing electronic neural networks.
