Question

Quizplus · Accepted Answer

Each retinal ganglion cell receives input from multiple photoreceptors via intermediate cells like bipolar cells and amacrine cells. This convergence of information from many photoreceptors onto one retinal ganglion cell helps to reduce the amount of information that needs to be transmitted to the brain, while still preserving important features of the visual scene.
