Most afferent fibers from the lateral geniculate nucleus terminate in the primary visual cortex is -
The axons from the lateral geniculate nucleus that form magnocellular pathway end in layer 4 of visual cortex, specifically in its deepest part, layer 4C. Many of the axons that form the parvocellular pathway also end in layer 4C.
