The topography and cytoarchitectonics of the claustrum as well as morphometric parameters of its neurons were studied in 10 human brains obtained from patients without any detectable neuropathological changes. We distinguished four parts of the claustrum: dorsal, orbital, temporal and paraamygdalar. The dorsal and orbital parts contain larger cells, than those of the temporal and paraamygdalar parts, although these differences were statistically non significant. The highest neuronal density was observed in the paraamygdalar part. The nucleus and nucleus@cell body area ratio was significantly smaller in the dorsal part than in other parts of the claustrum. We described three types of neurons in the claustrum: (1) medium-sized either fusiform or triangular cells with darkly stained cytoplasm; they predominate in the dorsal and temporal parts, (2) medium-sized as well as large cells, either multipolar or pyramidal-like with lightly stained cytoplasm; they are most numerous in the orbital and paraamygdalar parts, (3) small, multipolar or oval neurons with darkly stained ring of cytoplasm; these types of neurons are uniformly distributed throughout all parts of the claustrum. The subdivision of the human claustrum is in accordance with our observations that each of these parts possesses connections with different cortical regions.
在取自无任何可检测到神经病理变化患者的10个人类大脑中，研究了屏状核的局部解剖结构、细胞构筑以及其神经元的形态测量参数。我们区分出屏状核的四个部分：背侧部、眶部、颞部和杏仁旁部。背侧部和眶部的细胞比颞部和杏仁旁部的细胞大，尽管这些差异在统计学上不显著。杏仁旁部观察到最高的神经元密度。背侧部的细胞核与细胞核@细胞体面积比显著小于屏状核的其他部分。我们在屏状核中描述了三种类型的神经元：(1)中等大小的梭形或三角形细胞，细胞质染色深；它们在背侧部和颞部占主导，(2)中等大小以及大的细胞，多极或锥体形，细胞质染色浅；它们在眶部和杏仁旁部数量最多，(3)小的、多极或椭圆形神经元，细胞质有深色染色环；这些类型的神经元均匀分布在屏状核的所有部分。人类屏状核的细分与我们的观察结果一致，即这些部分中的每一个都与不同的皮质区域有联系。
