The various cell layers of the retina, including bipolar cells, ganglion cells, and horizontal cells, process visual signals to obtain more precise visual information. They facilitate the transmission of signals from the rods and cones to the brain by combining, inhibiting, and sharpening the signals. This processing allows the brain to distinguish different colors, contrasts, and spatial patterns in the visual scene.
