一、杏仁核的解剖和生理功能杏仁核又称杏仁样核、杏仁样复合体,属于嗅脑皮质下结构或边缘系统皮质下结构.杏仁核的解剖位置因动物种属而异,但在大多数哺乳动物中,它位于颞叶背内侧部,侧脑室下角尖端的前上方,背邻豆状核,尾侧联于尾状核,咀侧毗邻前穿质.人脑中,杏仁核是海马回钩的一部分,位于海马脚咀侧末端之前,借侧脑室下脚裂隙状顶端与海马分离.杏仁核可分为许多亚核,亚核的数量(5～22个)虽各家报告不同,但皮层内侧核和基底外侧核是公认的两个最大的亚核.杏仁核的纤维联系十分复杂,其传出径路主要是终纹和腹侧离杏仁核径路.前者在
Anatomical and physiological functions of the amygdala Amygdalus, also known as almond-like nucleus, almond-like complex, belongs to the sub-genital structure of the snortal cortex or the limbic system.The anatomic location of the amygdala varies depending on animal species, but in large In most mammals, it is located in the medial temporal portion of the temporal lobe, anteromedially above the tip of the lower horn of the lateral ventricle, posterior to the putamen, caudal to the caudate nucleus, A portion of the hook, located just before the end of the hippocampus, is separated from the hippocampus by the fissure-like apical fissure of the lateral ventricle. The amygdala may be divided into subnuclei, the number of which may vary from 5 to 22 Cortical medial and basolateral nuclei are recognized as the two largest subnuclear.The amygdala fiber connection is very complex, its outgoing path is mainly the terminal and ventral amygdala route.The former is in the
