Horizontal cells are specialized neurons found in the retina of the eye. They play a crucial role in processing visual information by connecting photoreceptors, such as rods and cones, to bipolar cells. This connection helps to integrate and regulate the signals received from light, enhancing contrast and improving visual acuity. These cells are named for their horizontal arrangement in the retinal structure. By facilitating lateral communication between photoreceptors, horizontal cells contribute to the overall function of the retinal circuitry, allowing for better detection of edges and patterns in the visual field.
