Human retinal oscillatory potentials in response to an alternating checker-board pattern stimulus were studied in two subjects over an intensity range of 7.5 log units. Under scotopic conditions, two wavelets (S1 and S2) could be recorded. At an intensity of 1.9 photopic log Td four high frequency oscillations (O1--O4) were noticed and a discontinuity was observed in the corresponding luminance curve of the b-wave together with a sudden decrease in the magnitude of the standard deviation of the amplitude measures. The oscillations were noticed only on the ascending slope of the b-wave. With increasing stimulus intensity, their latency decreased at a slower rate than that of the b-wave and their number decreased. Each wavelet had an amplitude maximum at a certain stimulus intensity level. It was suggested that O1--O4 were generated by the activation of the photopic system and that S1 and S2 were of scotopic origin.
在两名受试者中，研究了人类视网膜对交替棋盘图案刺激的振荡电位，强度范围为7.5对数单位。在暗视条件下，可以记录到两个小波（S1和S2）。在明视对数Td为1.9时，观察到四个高频振荡（O1 - O4），并且在b波的相应亮度曲线中观察到不连续性，同时幅度测量的标准差大小突然下降。这些振荡仅在b波的上升斜率上被观察到。随着刺激强度增加，它们的潜伏期比b波下降得慢，并且数量减少。每个小波在特定的刺激强度水平处具有最大幅度。有人提出，O1 - O4是由明视系统的激活产生的，而S1和S2起源于暗视。
