title: Neuronal types and their percent distribution within the magnocellular nuclei of the human basal forebrain.
abstract: Three neuronal types constituting the magnocellular nuclei of the human basal forebrain have been differentiated with the aid of preparations stained for both Nissl material and pigment deposits: type I = large multipolar neurons contain loosely packed and faintly stained lipofuscin granules occupying a large portion of the cell body; type II = large spindle-shaped neurons reveal a densely packed accumulation of coarse and intensely stained lipofuscin granules, and type III = small nerve cells, scattered among these large neuronal components, with only a small number of faintly stained lipofuscin granules. The determination of the projection areas of the somata of the three neuronal types has led to a distribution pattern with three peaks. The ratio of the nerve cell types has been evaluated: 73.6% type I; 8.6% type II, and 17.8% type III neurons.
