应用辣根过氧化酶(HRP)逆行传递法追踪了大白鼠杏仁外侧核,基底核传入性纤维的起源。实验表明HRP酶标记神经元分布于下: 将酶注入杏仁外侧核后,HRP酶标记细胞主要见于前梨状区、杏仁周围区、内嗅区,下脚;内侧膝状体,室周核、带旁核,丘脑底核和无名质当酶注入杏仁基底核时,标记细胞主要见于终纹床核、视前内侧核、内侧膝状体,丘脑腹内侧基底核、视交叉上核、弓状核下丘脑腹内侧核、黑质、脚周核、中央灰质腹外侧区、中缝背核,臂旁核和兰斑。由脑侧面斜行刺入和水平刺入酶的例子中,在嗅沟以上的新皮质内未见标记细胞,在一例O—D法成色切片中,在延随的弧束核内见到2—3个标记神经元。在下丘脑腹内侧核见双侧标记外,其他部位标记仅见于注射的同侧。组成杏仁复合体的许多亚核根据胚胎学、比较解剖学、细胞构筑及神经化学等方面特点可分为两大群、即皮质内侧核群和基底外侧核群(参阅Offersen‘)。我们在应用HRP酶法对属皮质内侧核群的杏仁内侧核和中央核作传入性联系研究之后,又选择了属基底外侧核群中的杏仁外侧核、基底核的传入性联系作研究探讨,以期为杏仁复合体各亚核的功能不同提供一定形态学基础。
Horseradish peroxidase (HRP) retrograde transfer method was used to trace the origin of alien nucleus and basal ganglia in rats. Experiments show that the HRP enzyme labeled neurons are distributed in the following: After the enzyme is injected into the lateral almond nucleus, HRP enzyme-labeled cells are mainly found in the anterior pear area, the almond area, the entorhinal area and the lower extremity; the medial geniculate body, the periventricular nucleus, Paraventricular nucleus, subthalamic nucleus, and unqualified quality When the enzyme is injected into the basal nucleus of almond, the labeled cells are mainly found in the nucleus of the dorsal horn, the preoptic medial nucleus, the medial geniculate body, the ventromedial thalamic nucleus, the suprachiasmatic nucleus, the arcuate nucleus Hypothalamic ventrolateral medulla, substantia nigra, perinuclear area, central ventrolateral medulla, dorsal raphe, parabrachial nucleus and blue spots. In the case of obliquely penetrating and horizontally penetrating enzymes in the brain, no marked cells were seen in the neocortex above the olfactory groove. In one case of O-D staining, 2 -3 labeled neurons. In the ventromedial hypothalamic nuclei see bilateral markers, other parts of the mark only found in the ipsilateral injection. Many sub-nuclei that make up the almond complex can be divided into two groups based on embryology, comparative anatomy, cell architecture, neurochemistry, etc. The inner cortical nucleus and the basolateral nuclei (see Offersen). After applying HRP enzymatic method to study the afferent connection of the medial and lateral nucleus of the inner cortical nucleus, we selected the afferent connection of the lateral almond and basal nucleus in the basolateral nucleus group Explore, in order to provide a certain morphological basis for the different functions of the sub-nuclei of almond complex.
