In this paper we examine the use of a symmetric binary random stimulus for eliciting the ERG, and for calculating the first-order and second-order kernels of a nonlinear functional expansion of the response. We show that if the stimulus is represented in a non-dimensional form, then the units in which all kernels are measured are the same as the units used to measure the response, microvolts in the case of the ERG; further, contributions from all kernels to the response can be added without scale factors. We present the first-order and second-order kernels measured for a population of 15 normal subjects in a clinical setting. The measurements were made at various levels of adaptation ranging from photopic to scotopic conditions. The second-order kernels illustrate the processes of rapid adaptation (less than 100 ms) in the retina.
在本文中，我们研究了使用对称二元随机刺激来诱发视网膜电图（ERG），以及计算响应的非线性泛函展开的一阶和二阶核。我们表明，如果刺激以无量纲形式表示，那么所有核的测量单位与用于测量响应的单位相同，在ERG的情况下为微伏；此外，所有核对响应的贡献可以无比例因子地相加。我们展示了在临床环境中对15名正常受试者群体测量的一阶和二阶核。测量是在从明视觉到暗视觉条件的各种适应水平下进行的。二阶核说明了视网膜中的快速适应过程（小于100毫秒）。
