A linear analysis approach has been applied to determine the dynamic characteristics of the color-coded S-potentials. Using a sinusoidally modulated light stimulus it could be shown that the monophasic S-potential as well as each of the different components of biphasic and triphasic S-potentials behaves linearly. However, for high modulation depths and high average intensities nonlinear effects, such as saturation, become obvious. The transfer characteristics of the monophasic potentials and each component of the biphasic and triphasic potentials are indistinguishable. Their latencies, however, differ. These findings suggest that the three different types of S-potentials not only originate from functionally comparable cells but also that the dynamic characteristics of the cells presynaptic to the S-potential sources are identical.
已应用线性分析方法来确定颜色编码S电位的动态特性。使用正弦调制光刺激可以表明，单相S电位以及双相和三相S电位的每个不同成分都呈线性行为。然而，对于高调制深度和高平均强度，非线性效应（如饱和度）变得明显。单相电位以及双相和三相电位各成分的传递特性无法区分。然而，它们的潜伏期不同。这些发现表明，三种不同类型的S电位不仅源自功能上可比的细胞，而且S电位源突触前细胞的动态特性是相同的。
