开发了一种模型膜，其中视紫红质的界面层被重新定向到将两个水室分开的薄聚四氟乙烯膜的一侧上。闪烁引起的快速光电信号（1毫秒），起源于漂白时的定向视紫红质的电容电荷位移。模型膜中的视紫红质的光电响应与感光细胞的早期受体电位进行了比较，可以得出结论，这两个系统中的信号来源于相同的机制。
A model membrane was developed in which interfacial layers of rhodopsin were reoriented onto one side of a thin Teflon film separating two aqueous compartments. Flashes evoked fast photoelectric signals (1 ms) that originated from capacitative charge displacements of oriented rhodopsin upon bleaching. The photoelectric responses of rhodopsin in the model membrane are compared with the early receptor potential of photoreceptor cells; it is concluded that the signals in both systems originate from the same mechanism.
