Abstract:
UNASSIGNED: The amygdala is a noticeable bilateral structure in the medial temporal lobe and it is composed of at least 13 different nuclei and cortical areas, subdivided into the deep nuclei, the superficial nuclei, and the remaining nuclei which contain the central nucleus (CeA). CeA mediates the behavioral and physiological responses associated with fear and anxiety through pituitary-adrenal responses by modulating the liberation of the hypothalamic Corticotropin Releasing Factor/Hormone.
UNASSIGNED: Five dolphins of three different species, belonging to the family Delphinidae (three striped dolphins, one common dolphin, and one Atlantic spotted dolphin), were used for this study. For a precise overview of the CeA\'s structure, thionine staining and the immunoperoxidase method using calbindin D-28k were employed.
UNASSIGNED: CeA extended mainly dorsal to the lateral nucleus and ventral to the striatum. It was medial to the internal capsule and lateral to the optic tract and the medial nucleus of the amygdala.
UNASSIGNED: The dolphin amygdaloid complex resembles that of primates, including the subdivision, volume, and location of the CeA.
摘要:
杏仁核是内侧颞叶中明显的双侧结构,由至少13个不同的核和皮质区域组成,细分为深核,浅层核,以及包含中央核(CeA)的其余核。CeA通过调节下丘脑促肾上腺皮质激素释放因子/激素通过垂体-肾上腺反应介导与恐惧和焦虑相关的行为和生理反应。
五只不同物种的海豚,属于德尔菲科(三只条纹海豚,一只普通的海豚,和一只大西洋发现的海豚),用于这项研究。有关CeA\的结构的精确概述,采用硫氨酸染色和使用钙结合蛋白D-28k的免疫过氧化物酶方法。
CeA主要在背侧向外侧核延伸,在腹侧向纹状体延伸。它位于内囊的内侧,视神经束和杏仁核的内侧核的外侧。
海豚杏仁核复合体类似于灵长类动物,包括细分,volume,和CeA的位置。
