Variable duration square wave pulses of 633-nm light were used to produce electroretinograms (ERG's) in a human subject. When the stimuli were presented on a white light background, the records obtained for stimulus durations greater than 70 msec showed a clearly separated off-response while those of shorter durations did not. By subtracting a common "on-effect" from the ERG's produced by short duration stimuli, the previously unseen off-effect was isolated from records produced by stimulus pulses as short as 5 msec. It appears that the marked increase in b-wave amplitude associated with these short duration stimuli can be attributed to an interaction between "on" and "off" components of the ERG.
使用633纳米可变持续时间的方波脉冲光在一名人类受试者身上产生视网膜电图（ERG）。当刺激呈现于白色背景光上时，对于持续时间大于70毫秒的刺激所获得的记录显示出明显分离的关闭反应，而较短持续时间的刺激记录则未显示。通过从短持续时间刺激产生的ERG中减去共同的“开启效应”，从短至5毫秒的刺激脉冲产生的记录中分离出了之前未被观察到的关闭效应。似乎与这些短持续时间刺激相关的b波振幅显著增加可归因于ERG的“开启”和“关闭”成分之间的相互作用。
