The lateral geniculate nucleus (LGN) is a structure located in the thalamus of the brain. It plays a crucial role in processing visual information received from the eyes. The LGN acts as a relay center, receiving signals from the retina and sending them to the primary visual cortex for further interpretation. The LGN is organized into layers, with each layer processing different aspects of visual information, such as color and motion. It is essential for our ability to perceive and interpret visual stimuli, making it a key component in the visual pathway that connects the eyes to the brain.
