WebIn mammals, the visual thalamus, the lateral geniculate nucleus (LGN), relays visual information from the retina to the primary visual cortex (V1) and also receives feedback from V1. Both retinal and cortical inputs are critical to processing visual information within the LGN. The role of the LGN in residual vision following loss of retinal or ... WebThe lateral geniculate nucleus (LGN) of the thalamus is the principal relay station for visual information as it travels to the visual cortex.
