Abstract

Signals from both the rod and the cone receptor systems converge upon the same retinal ganglion cell, but only one or the other of these systems appears to be effective at any particular level of adaptation. In this report we provide evidence that the change from one receptor system to the other is not simply due to the two systems having nonoverlapping dynamic ranges; rather, there is a distance-dependent interaction between the two systems.

摘要

来自视杆和视锥受体系统的信号都汇聚到同一个视网膜神经节细胞上，但在任何特定的适应水平上，这两个系统中似乎只有一个是有效的。在本报告中，我们提供的证据表明，从一个受体系统转换到另一个受体系统，并非仅仅是因为这两个系统具有不重叠的动态范围；相反，这两个系统之间存在距离依赖性相互作用。
