Abstract

Our ability to see in dim light is limited by the statistics of light absorption in rod photoreceptors and the faithful transmission of the light-evoked signals through the retina. This article reviews the physiological mechanisms at the synapse between rods and rod bipolar cells, the first relay in a pathway that mediates vision near absolute threshold.

摘要

我们在暗光下的视觉能力受到视杆光感受器中光吸收统计数据以及光诱发信号通过视网膜的可靠传递的限制。本文综述了视杆细胞与视杆双极细胞之间突触处的生理机制，这是介导接近绝对阈值视觉的通路中的第一个中继环节。
