L- and M-cone driven on- and off- ERG responses and their interactions were examined using full field stimuli with sawtooth temporal profiles. The effects of temporal frequency and contrast were studied. ERG recordings were obtained from 21 trichromatic, 1 protanopic, and 1 deuteranopic subjects. ERGs to L-cone increments and decrements resembled those to M-cone decrements and increments, respectively (i.e., of the opposite polarity). Temporal frequency and contrast had little effect on the implicit times. All response components varied linearly with contrast. When stimulated simultaneously, the responsivities of most components were larger for counterphase than for inphase modulation. The retinal processing leading to an ERG response is reversed for L- and M-cone driven responses.
使用具有锯齿形时间轮廓的全视野刺激来检查L-和M-视锥细胞驱动的开-关视网膜电图（ERG）反应及其相互作用。研究了时间频率和对比度的影响。从21名三色视者、1名红色盲者和1名绿色盲者获得了ERG记录。对L-视锥细胞增量和减量的ERG分别类似于对M-视锥细胞减量和增量的ERG（即，极性相反）。时间频率和对比度对隐含时间影响很小。所有反应成分随对比度呈线性变化。同时刺激时，大多数成分的反应性在反相调制时比同相调制时更大。导致ERG反应的视网膜处理对于L-和M-视锥细胞驱动的反应是相反的。
