WebHorizontal cells are the laterally interconnecting neurons in the outer plexiform layer of the retina of mammalian eyes. They help integrate and regulate the input from multiple photoreceptor cells. Among their functions, horizontal cells are responsible for allowing eyes to adjust to see well under both bright and dim light conditions. Contents WebThe main function of the horizontal cells is to vary the extent of coupling between photoreceptors and between photoreceptors and bipolar cells. This provides a control system that keeps the activity of the bipolar cells within limits, regardless of fluctuations in the intensity of light reaching the receptors.
