在感觉细胞放电和最终感觉的数量方面之间不存在简单的关系。视神经纤维中有三种不同类型的放电。(2)眼睛的功能单位反应不够快，不能使整个眼睛对快速闪光作出反应。它们必须交替反应，这可以解释对均匀闪光的不规则响应大小和随着闪光频率增加而产生的过多和不断变化的延迟。(3)闪烁速率与闪烁速率不同步。(4)闪光序列中的亮度识别受到中枢神经节律的扭曲。刺激中的轮廓可能不会出现在感觉中。(6)刺激中等高线的排列会影响其他等高线或视野部分的可见性。（PsycINFO数据库记录(c) 2017 APA，版权所有）
No simple relation exists between sense-cell discharge and the quantitative aspects of the final sensation.(1) There are three distinct types of discharge in the optic nerve fibers.(2) The functional units of the eye cannot respond fast enough for the eye as a whole to react to rapid flashes. They must react alternately, and this may account for the irregular size of responses to uniform flashes and the excessive and changing latencies, with increased flash frequency.(3) Flicker rate does not keep pace with flash rate.(4) Brightness discrimination in a flash series is distorted by a central neural rhythm.(5) Contours in the stimulus may fail to appear in the sensation.(6) Arrangement of contours in the stimulus affects the visibility of other contours or parts of the visual field.(PsycINFO Database Record (c) 2017 APA, all rights reserved)
