Longitudinal spread of the light response was studied using cell-attached patch-clamp recordings from the outer segments of isolated rod photoreceptors from toad retina. The effective photon-collecting area over which photoisomerizations influenced the membrane current through the recorded patch of membrane was determined by measuring the probability of a detectable response as a function of flash photon density (i.e. a "frequency-of-seeing" experiment). The effective collecting area averaged 0.40 micron2, which corresponds to a total sampling length of approximately 1 micron for the patch electrode.
利用从蟾蜍视网膜分离出的视杆光感受器外段进行细胞贴附式膜片钳记录，研究了光反应的纵向传播。通过测量可检测反应的概率作为闪光光子密度的函数（即“看见频率”实验），确定了光异构化通过记录的膜片影响膜电流的有效光子收集面积。有效收集面积平均为0.40平方微米，这对应于膜片电极的总采样长度约为1微米。
