摘要

杏仁核的中央核是一个高级边缘中心,控制着营养功能并参与神经退行性疾病。在本研究中,我们用颜料尼索技术研究了人类杏仁核的中央核和嵌入团块。杏仁核的中央核由一个被纤维束包围的主体和位于主体背面的附属岛组成。在主体上,可以区分出具有重着色神经元型的中央内侧核和由三种亚核组成的外侧中央核:中央外侧核具有重着色和稀疏着色的神经元型,顶端外侧中央核稀疏着色的神经元型和被囊外侧中央核重着色的神经元型。根据色素结构,中央核的附属岛是尖外侧和包膜外侧中央核的一部分。总的来说,中央内侧核有八种神经元类型,而中央外侧核的亚核有四到六种神经元类型。在嵌入的肿块中,有四种神经元类型,主要细胞类型小且色素稀疏。综上所述,尼氏染色显示,人杏仁核外侧中央核有三个亚核,副岛是其中两个亚核的一部分。此外,在中央核和杏仁核的嵌入团块中发现了许多神经元类型,这可能反映了它们神经化学特征的可变性。

The pigmentarchitectonic divisions and neuronal types of the central nucleus and intercalated masses of the human amygdala.

The central nucleus of the amygdala is a high level limbic center which controls vegetative functions and is involved in neurodegenerative diseases. In the present study, the central nucleus and intercalated masses of the human amygdala have been investigated with the pigment Nissl technique. The central nucleus of the amygdala consists of a main body surrounded by fiber tracts and accessory islands located dorsal to the main body. In the main body, one can distinguish the medial central nucleus with heavily pigmented neuronal types and the lateral central nucleus, which is composed of three subnuclei: the centro-lateral central nucleus has heavily and sparsely pigmented neuronal types, the apico-lateral central nucleus sparsely pigmented neuronal types and the capsular-lateral central nucleus heavily pigmented neuronal types. Based on the pigmentarchitecture, the accessory islands of the central nucleus are part of the apico-lateral and capsular-lateral central nuclei. Altogether, there are eight neuronal types in the medial central nucleus, while four to six neuronal types are found in the subnuclei of the lateral central nucleus. In the intercalated masses, there are four neuronal types, and the predominating cell types are small and sparsely pigmented. In conclusion, the pigment Nissl stain shows that the lateral central nucleus of the human amygdala has three subnuclei, and the accessory islands are part of two of these subnuclei. Furthermore, numerous neuronal types are identified within the central nucleus and intercalated masses of the amygdala, which may reflect the variability in their neurochemical characteristics.
