Amygdalostriatal projections in the rat were studied with the anterograde tracer phaseolus vulgaris leucoagglutinin (PHA-L), which allows direct visualization of axon morphology. The appearance of fibers in the striatum which were labeled from injections into the amygdaloid complex suggests that they form 'en passant' synapses. A topographic organization was found in the projection from the basolateral amygdaloid nucleus: the most caudal part of this nucleus projects to the anteromedial edge of the striatum, including the medial nucleus accumbens, while progressively more rostral parts of the nucleus project to more lateral and caudal portions of the striatum. No amygdaloid fibers were found in the most rostro-dorsolateral part of the caudatoputamen.
采用顺行示踪剂菜豆白细胞凝集素（PHA-L）对大鼠杏仁核-纹状体投射进行了研究，该示踪剂可直接观察轴突形态。从杏仁复合体注射标记后纹状体中出现的纤维表明它们形成“沿途”突触。在基底外侧杏仁核的投射中发现了一种拓扑组织：该核最尾端部分投射到纹状体的前内侧边缘，包括伏隔核内侧，而该核逐渐靠前的部分投射到纹状体更外侧和尾端部分。在尾壳核最前端-背外侧部分未发现杏仁核纤维。
