WebThe electrical signals then travel to the lateral geniculate nucleus (LGN) of the thalamus, which acts as a relay station for the signals. From the LGN, the signals are sent to the primary visual cortex (V1) in the occipital lobe. This is the main processing area for visual information in the brain. In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway.
