泥巴狗视杆和视锥反应在恢复的时间进程和绝对灵敏度上都不同。棒的灵敏度大约是锥体的25倍，而且似乎每吸收一个量子产生更大的电压。泥巴小狗与其他脊椎动物受体敏感性的比较表明，杆状和锥状之间的敏感性差异可能是一种普遍现象。
Mudpuppy rod and cone responses differ both in time course of recovery and in absolute sensitivity. Rods are about 25 times more sensitive than cones and appear to generate a larger voltage per quantum absorbed. Comparison of mudpuppy receptor sensitivities to those of other vertebrates suggests that the difference in sensitivity between rods and cones may be a general phenomenon.
