The amygdaloid formation of the lizard Podarcis hispanica can be divided into three main groups of nuclei on the basis of their input from the main and accessory olfactory bulbs: the vomeronasal amygdala, the olfactory amygdala and the dorsal amygdaloid group, the latter group receiving afferents from neither the main (MOB) or the accessory olfactory bulb (AOB). The vomeronasal amygdala has a centrifugal projection to the AOB, an important commissural connection to the contralateral vomeronasal amygdala, a minor projection to nucleus accumbens, and a bilateral projection to the lateral cortex. The olfactory amygdala displays a bilateral afferents from the MOB, receives a contralateral afferent, and is reciprocally connected with the lateral cortex. Moreover, it receives an important input from the vomeronasal amygdala. The dorsal amygdaloid group receives projections from the other two amygdaloid groups, multimodal inputs from the anterior dorsal ventricular ridge and the dorsal cortex, and a putative cholinergic input from the basal telencephalon. Moreover, it is the site of origin of a prominent bilateral amygdalo-striatal projection that extends to the bed nucleus of the stria terminalis and the so-called amygdalo-striatal transition area, through which it may control both visceral and motor activities. The main extratelencephalic output of the amygdala courses through the stria terminalis and terminates in the ventromedial hypothalamic nucleus. The extratelencephalic afferents of the amygdala arise from several hypothalamic and anterior thalamic nuclei, from the mesencephalic and rhombencephalic aminergic cell groups, and from the rhombencephalic parabrachial nucleus.
根据来自主嗅球和副嗅球的输入，西班牙壁蜥（Podarcis hispanica）的杏仁核复合体可分为三个主要核团组：犁鼻杏仁核、嗅杏仁核和背侧杏仁核组，后一组既不接受来自主嗅球（MOB）也不接受来自副嗅球（AOB）的传入纤维。犁鼻杏仁核对副嗅球有离心投射，与对侧犁鼻杏仁核有重要的连合连接，对伏隔核有少量投射，对外侧皮质有双侧投射。嗅杏仁核有来自主嗅球的双侧传入纤维，接受对侧传入纤维，并与外侧皮质相互连接。此外，它还接受来自犁鼻杏仁核的重要输入。背侧杏仁核组接受来自其他两个杏仁核组的投射、来自前背侧脑室嵴和背侧皮质的多模态输入以及来自基底前脑的假定胆碱能输入。此外，它还是一条突出的双侧杏仁核 - 纹状体投射的起源部位，该投射延伸至终纹床核和所谓的杏仁核 - 纹状体过渡区，通过该区域它可能控制内脏和运动活动。杏仁核的主要脑外输出通过终纹，终止于下丘脑腹内侧核。杏仁核的脑外传入纤维来自几个下丘脑和丘脑前核、中脑和后脑的胺能细胞群以及后脑的臂旁核。
