Abstract
B-wave increment threshold experiments in the rat show that "rod saturation" occurs at different background levels with different anesthetics. Rod saturation builds up over the first 60 sec of light adaptation in pentobarbital anesthetized but not in urethane anesthetized animals. These and other findings suggest that "rod saturation" can occur when the rod photoreceptors themselves are not saturated.
摘要
对大鼠进行的B波增量阈值实验表明，在不同麻醉剂作用下，“视杆细胞饱和”在不同背景水平时出现。在戊巴比妥麻醉的动物中，视杆细胞饱和在光适应的最初60秒内逐渐形成，但在氨基甲酸乙酯麻醉的动物中则不会。这些以及其他研究结果表明，当视杆光感受器本身未饱和时，“视杆细胞饱和”就可能发生。
