Neuronal types and their percent distribution within the magnocellular nuclei of the human basal forebrain.
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.
