Cytoarchitectonics of the lateral tuberal nucleus--a phylogenetically new hypothalamic structure--was investigated using morphometric methods. The most characteristic feature of the human lateral tuberal nucleus is an extremely great variability of its shape and segmentation. The lateral tuberal nucleus consists mostly of several separated neuronal groups; in each brain the arrangement of these groups is different. In macaca the lateral tuberal nucleus is a single elongated neuronal structure much less variable than in man. The human LTN is approximately ten times larger than that in macaca, but the number of neurons is only about four times higher due to a lower neuronal density. The lateral tuberal nucleus both of man and macaca is a homogenous neuronal population with a very low coefficient of variability of cross-section neuronal area (30% and 24% respectively). The size of neuronal bodies in the lateral tuberal nucleus is about 42% smaller in macaca than in man. However, the size of neuronal nuclei is slightly (15%) bigger and the nucleus/cell body area ratio is about twice as high in macaca as that in man (40% and 21% respectively).
运用形态测量学方法对外侧结节核（一种系统发育上新出现的下丘脑结构）的细胞构筑进行了研究。人类外侧结节核最显著的特征是其形状和分隔具有极大的变异性。外侧结节核主要由几个分离的神经元群组成；在每个大脑中，这些群组的排列方式都不同。在猕猴中，外侧结节核是一个单一的细长神经元结构，其变异性比人类小得多。人类的外侧结节核大约是猕猴的十倍大，但由于神经元密度较低，神经元数量仅约为猕猴的四倍。人类和猕猴的外侧结节核都是均匀的神经元群体，横截面神经元面积的变异系数非常低（分别为30%和24%）。猕猴外侧结节核中神经元胞体的大小比人类小约42%。然而，猕猴中神经元细胞核的大小略大（15%），且细胞核/细胞体面积比约为人类的两倍（分别为40%和21%）。
