Neural circuits associated with dorsal lateral geniculate nucleus (dLGN). Wiring diagram showing the pattern of connectivity between neurons of dLGN, retina, brain stem, visual cortex (VC), thalamic reticular nucleus (TRN), and superior colliculus (SC). DS, direction selective retinal ganglion cells; i, inhibitory neurons; X, Y and W, different classes of relay neurons; sgs, stratum griseum superficialis; +/−, excitatory or inhibitory input.
