Lateral Geniculate Nucleus - an overview | ScienceDirect Topics

The LGN is a striated structure occupying the dorsolateral part of the dorsal thalamus and transmits visual information to the visual cortex. From: Experimental Eye Research, 2011 F. Wang, in Encyclopedia of Neuroscience, 2009 The 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. Gradients of ephrins in the LGN and countergradients of Ephs in RGCs regulate the topographic mapping in the LGN. Moreover, in mammals, input from the two eyes segregates into stereotyped eye-specific layers in the LGN. The precise pattern of segregation requires the function of EphrinAs, whereas the segregation of the eye input per se depends on neural activity.
