Describe the five main types of connecting neurons in the retina and their functions. What will be an ideal response?

horizontal cells, which receive information from photoreceptors and send it to bipolar cells;
and 5) amacrine cells, which receive messages from bipolar cells and send them to ganglion
cells or bipolar cells.
