“杏仁核”和“杏仁复合体”现在是指哺乳动物大脑半球颞极附近高度分化的区域。其中的细胞群似乎是传统皮质、屏蔽体或纹状体的分化部分，这些部分属于四个明显的功能系统--副嗅觉、主嗅觉、自主神经和额颞叶皮质。在大鼠中，中央核是纹状体的一个专门的自主投射运动区，而外侧核和前基底外侧核一起是屏蔽体的腹内侧延伸，覆盖了颞叶和额叶的大部分区域。杏仁核的其余部分形成了嗅觉系统的联合部分(副和主要)，包括皮质、屏蔽核和纹状体部分。诸如“杏仁核”和“豆状核”这样的术语将细胞群任意组合在一起，而不是根据它们现在似乎所属的结构和功能单位。杏仁核既不是结构单位，也不是功能单位。
'Amygdala' and 'amygdalar complex' are terms that now refer to a highly differentiated region near the temporal pole of the mammalian cerebral hemisphere. Cell groups within it appear to be differentiated parts of the traditional cortex, the claustrum, or the striatum, and these parts belong to four obvious functional systems - accessory olfactory main olfactory, autonomic and frontotemporal cortical. In rats, the central nucleus is a specialized autonomic-projecting motor region of the striatum, whereas the lateral and anterior basolateral nuclei together are a ventromedial extension of the claustrum for major regions of the temporal and frontal lobes.The rest of the amygdala forms association parts of the olfactory system (accessory and main), with cortical, claustral and striatal parts. Terms such as 'amygdala' and 'lenticular nucleus' combine cell groups arbitrarily rather than according to the structural and functional units to which they now seem to belong.The amygdala is neither a structural nor a functional unit.
