一个简单的编码器模型，是已知电生理特性的合理理想化，产生一个种群，其中放电速率随时间的变化是输入刺激形状的完美复制品。一群无噪声编码器即使稍微偏离简单模型，也会产生输入刺激的降级副本。噪声的存在提高了这类人群的表现。一群神经元的放电速率以一种微妙的方式与单个神经元的放电速率相关。
A simple encoder model, which is a reasonable idealization from known electrophysiological properties, yields a population in which the variation of the firing rate with time is a perfect replica of the shape of the input stimulus. A population of noise-free encoders which depart even slightly from the simple model yield a very much degraded copy of the input stimulus. The presence of noise improves the performance of such a population. The firing rate of a population of neurons is related to the firing rate of a single member in a subtle way.
