Abstract

By means of the karyometry method 26 zones in the basolateral group of the amygdaloid complex (AC) nuclei in rats have been studied 1 month after castration. All the main parameters characterizing distribution of the neuronal nuclei volume logs in the zones studied have been calculated. In males two regions have been revealed, in which certain reaction of the cellular neuronal nuclei to the experimentally produced deficit of sex hormones in the organism is felt. One of them is situated in the AC anterior part and includes all the nuclei of the basolateral group, the second is situated in the posterior part, occupies a rather vast area and is formed at the expense of all the nuclei of the basolateral group and adjoining structures (the dorsal endopiriform nucleus and piriform cortex). In females there is one region responding to gonadectomy, which is mainly formed at the expense of central and posterior parts of the basolateral nucleus. Basing on the lack of the structural-functional uniqueness revealed in different parts of the cortico-medial and basolateral groups of the AC nuclei, it is suggested to distinguish anterior, central and posterior parts in their composition.

摘要

采用核测量法,对去势1个月后的大鼠杏仁复合体(AC)基底外侧核群中的26个区域进行了研究。计算了所研究区域中表征神经元细胞核体积对数分布的所有主要参数。在雄性大鼠中发现了两个区域,其中能感受到细胞神经元核对机体实验性产生的性激素缺乏有一定反应。其中一个位于AC前部,包括基底外侧核群的所有核;另一个位于后部,占据相当大的区域,由基底外侧核群的所有核以及相邻结构(背内侧梨状核和梨状皮质)构成。在雌性大鼠中,有一个区域对性腺切除术有反应,主要由基底外侧核的中部和后部构成。基于在AC核的皮质内侧和基底外侧核群不同部位未发现结构 - 功能独特性,建议在其组成中区分前部、中部和后部。
