Changes in retinal potential take place when the eye is adequately stimulated. This evoked response, the electroretinogram (ERG) is recorded in vivo by placing an electrode on the cornea, while the reference electrode is grounded elsewhere. In spite of a great deal of work in this field, the very meaning of ERG, in the frame of visual process, is not yet wholly understood. The present paper produces some data which show that the plot of visual performance vs. time, during the course of the day, runs parallel to that of the size of ERG. The meaning of this finding is discussed, by making reference to the electrical analog of the recording circuit, in terms of lumping approximation.
当眼睛受到充分刺激时，视网膜电位会发生变化。这种诱发反应，即视网膜电图（ERG），是通过将电极置于角膜上在活体中记录的，而参考电极接地于其他部位。尽管该领域已有大量研究工作，但在视觉过程框架内，ERG的确切意义尚未被完全理解。本文给出了一些数据，这些数据表明在一天当中视觉表现与时间的关系曲线与ERG大小的关系曲线是平行的。通过参考记录电路的电模拟，从集总近似的角度对这一发现的意义进行了讨论。
