WebIn mammals, thalamocortical circuits perform many of the functions that underlie this complex sensory processing. First-order (FO) thalamic nuclei, such as the dorsal lateral geniculate nucleus (dLGN), relay incoming signals to the cortex, which generates a percept and motor commands. This initial path from the FO thalamus to the cortex is well ... WebThe lateral geniculate nucleus (LGN) (also called the lateral geniculate body or lateral geniculate complex) is a relay center in the thalamus for the visual pathway. It receives a major sensory input from the retina. The LGN is the main central connection for the optic nerve to the occipital lobe. lights for roomWebThe 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. pear burner hose
