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. Each ganglion cell collects data from multiple photoreceptors, allowing it to integrate visual information before sending it through their long axons. These cells form the optic nerve, which carries visual signals to the visual cortex in the brain. Ganglion cells are essential for various visual functions, including detecting light intensity, color, and movement, contributing to our overall perception of the visual world.
