从人的角膜测量中分析了高频信号(快速视网膜电位或FRP)的适应性依赖关系。在明视、中视和暗视三种适应条件下，对两个正常的S眼进行窄带色觉刺激。信号被记录在两个通带，即宽带(0.2赫兹-2千赫)和高通(50赫兹-2千赫)。结果支持两个主要结论：(1)从人的角膜记录到的快成分(50赫兹以上)主要与明视机制有关；(2)模拟滤波技术产生的快成分没有迹象表明与任何单一的光谱机制存在差异。讨论了常规成分和FRP成分之间的关系，以及可能引发FRP信号的机制。
The adaptation dependence of high frequency signals (fast retinal potentials or FRP's) was analyzed from measures taken from the human cornea. Narrow band chromatic stimuli were presented to two normal S's under photopic, mesopic, and scotopic adaption conditions. Signals were recorded in two pass bands, broad band (0.2 Hz–2 kHz) and highpass (50 Hz–2 kHz). Results support two primary conclusions:(1) Fast components (above 50 Hz) recorded from the human cornea were related primarily to photopic mechanisms;(2) Fast components educted by analog filtering techniques gave no indication of being differentially related to any single spectral mechanisms. The relationship between conventional and FRP components are discussed with the mechanisms which may initiate the FRP signal.
