title: The percentage of projection neurons and interneurons in the human lateral geniculate nucleus.
abstract: Projection neurons and local circuit neurons of the human lateral geniculate nucleus (LGN) offer different patterns of lipofuscin pigmentation. One type of projection cell (type I neuron) and two varieties of local circuit neurons (type II and type III neurons) can be distinguished on account of their characteristic pigmentation. The majority of the nerve cells are type I projection neurons. Pigmented type II neurons comprise about 8.5% and type III neurons devoid of pigment amount to only 0.2% of the nerve cells.
