Abstract
The conditions were found (hypoxic state of the retina) under which exhausture of the transmitter in presynaptic endings of photoreceptors may be supposed from a decrease in responses of horizontal cells to electric stimulation of the retina. Under these conditions the electric stimulation is accompanied by a decrease in the number of small synaptic vesicles near the presynaptic membranes in cones. However, there are no reliable changes in the total number of vesicles in cone endings.
摘要
发现了这样一些情况（视网膜的缺氧状态），在此状态下，根据水平细胞对视网膜电刺激反应的降低，可以推测光感受器突触前末梢中递质的耗竭。在这些情况下，电刺激伴随着视锥细胞突触前膜附近小突触囊泡数量的减少。然而，视锥细胞末梢中囊泡的总数并没有可靠的变化。
