Flashcard 290: Which **magnocellular** layer of the lateral geniculate nucleus (LGN) receives **ipsilateral** retinal input?

Answer: Layer 2

Extra: The Lateral Geniculate Nucleus (LGN) consists of 6 layers: - **Magnocellular (M) layers**: 1 and 2 - **Parvocellular (P) layers**: 3, 4, 5, and 6 Input distribution: - **Ipsilateral (I) input**: Layers 2, 3, and 5 - **Contralateral (C) input**: Layers 1, 4, and 6 Therefore, **Layer 2** is the only magnocellular layer that receives ipsilateral retinal input. (Layer 1 receives contralateral magnocellular input).
