WebThe lateral geniculate nucleus (LGN) is located in the dorsal posterolateral thalamus. 1. Function. All visual information for conscious perception travels through the LGN [ 1 ]. The LGN regulates the flow and strength of visual information sent to the visual cortex. This regulation is influenced by extraretinal inputs to the LGN [ 2 ]. WebThe lateral geniculate nucleus of the thalamus is the other main target of RGCs and is the relay station for visual input to the cortex. RGC axons again form ordered projections that map the visual field onto the LGN. Molecular mechanisms similar to those that govern the retinotopic map in the OT/SC also regulate the retinogeniculate projections. emerald bay cannabis https://doontec.com
