在色素构筑分析的基础上，给出了人杏仁基底外侧核的切片。对高尔基体和去浸渍后的脂褐素色素染色的神经细胞进行检查，发现有3类神经细胞：I类神经元从细胞体的1极产生1个粗壮的主树突，从与主突起相对的底部产生几个小的树突。树突上长满了刺。轴突呈直线走行，发出大量侧支。外侧基底核和副基底核中的I类神经元含有颗粒细小、分布广泛的色素。位于基核的细胞储存了大量的色素，集中在细胞体的1极。颗粒核和间质细胞团中的小I类神经元以大的空泡化的色素颗粒为标志。II类神经元具有光滑的轮廓或疏松的树突。它们细胞体的大小和形状各不相同。它们含有大量粗大且染色深的脂褐素颗粒。Ⅲ类神经元在高尔基体中表现出类似的特征，但它们的细胞体没有色素。一种常见的类型是具有细小树突和大量分支的局部轴突的微小细胞。每种不同类别的神经元都表现出一种特有的色素沉积模式。尼氏染色与色素染色技术相结合，提供了区分棘突和稀疏棘突或棘突类型神经元的独特优势。
A parcellation of the human basolateral amygdala is given on the basis of pigmentoarchitectonic analysis. Examination of Golgi preparations and deimpregnated preparations counterstained for lipofuscin pigment revealed 3 classes of nerve cells: class I neurons generate a stout main dendrite from 1 pole of the cell body and several minor ones from the base opposite to the main process. The dendrites are covered with spines. The axon follows a straight course and gives off numerous collaterals. Class I neurons in the lateral and accessory basal nucleus contain finely granulated and widely dispersed pigment. Cells located in the basal nucleus store a large amount of pigment, concentrated at 1 pole of the cell body. The small class I neurons in the granular nucleus and the intercalated cell masses are marked by large vacuolated pigment granules. Class II neurons have smoothly contoured or sparsely spined dendrites. Size and shape of their cell bodies vary. They contain a large amount of coarse and intensely stained lipofuscin granules. Class III neurons display similar features in the Golgi preparation but their cell bodies are devoid of pigment. A frequently occurring type is a tiny cell with thin dendrites and profusely branching local axon. Each of the different classes of neurons shows a characteristic pattern of pigmentation. Nissl preparations combined with a pigment staining technique, offer the particular advantage of distinguishing the spine-laden neurons from sparsely spined or aspinous types.
