Afferent and efferent projections of rodent dLGN. (A) Sources of afferent projections to dLGN are colored green. (B) Brain regions innervated by dLGN efferents are colored in orange. dLGN, dorsal lateral geniculate nucleus; vLGN, ventral lateral geniculate nucleus; TRN, thalamic reticular nucleus; SC, superior colliculus; PRT, pretectal region; MRN, midbrain reticular nucleus; DR, dorsal raphe nucleus; PPN, pedunculopontine nucleus; PBG, parabigeminal nucleus; PB, parabrachial nucleus; LC, locus coeruleus; VIS1, visual cortex, layer I; VIS4, visual cortex, layer IV; VIS6, visual cortex, layer VI; RGC, retinal ganglion cell.
