A new approach to study the function of the retina is described. It involves a precise revealing of synaptic connections between the neurons by means of three-dimensional volume reconstructions. Identification of several hundreds of synapses revealed the existence of groups of synaptically interconnected neurons constituting discrete neural circuits accounting for processing of information contributed by the photoreceptors. Supplementary information contributed by electrophysiological recordings of membrane potentials of neurons in these circuits made it possible to determine how information is processed by the circuits. Two versions of one of the circuits are analyzed in this communication.
本文描述了一种研究视网膜功能的新方法。它涉及通过三维体积重建精确揭示神经元之间的突触连接。对数百个突触的识别揭示了存在由突触相互连接的神经元组成的群体，这些群体构成了负责处理光感受器提供的信息的离散神经回路。通过对这些回路中神经元膜电位的电生理记录所提供的补充信息，使得确定这些回路如何处理信息成为可能。本文分析了其中一个回路的两个版本。
