Ganglion cells are a type of neuron located in the retina of the eye. They play a crucial role in processing visual information by receiving signals from photoreceptors, such as rods and cones, and transmitting these signals to the brain via the optic nerve. These cells are essential for vision, as they help convert light into electrical impulses that the brain interprets as images. There are different types of ganglion cells, each responsible for various aspects of vision, including color detection and motion perception. Their proper functioning is vital for clear and accurate sight.
