摘要

导言杏仁核是位于颞叶内侧的一个明显的双侧结构，它由至少 13 个不同的核团和皮质区域组成，可细分为深核、浅核和包含中央核（CeA）的其余核团。CeA 通过调节下丘脑促皮质素释放因子/激素的释放，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。方法本研究使用了五条海豚，它们分别属于海豚科的三个不同物种（三条条纹海豚、一条普通海豚和一条大西洋斑纹海豚）。为了准确了解 CeA 的结构，研究人员采用了亚硫酸染色法和使用钙宾丁 D-28k 的免疫过氧化物酶法。讨论海豚杏仁核复合体与灵长类动物相似，包括CeA的细分、体积和位置。

The amygdaloid body of the family Delphinidae: a morphological study of its central nucleus through calbindin-D28k

IntroductionThe 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.MethodsFive 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.ResultsCeA 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.DiscussionThe dolphin amygdaloid complex resembles that of primates, including the subdivision, volume, and location of the CeA.
