用顺行示踪法研究了猕猴杏仁核和海马结构之间的相互联系。海马杏仁核的输入来自下托和内嗅皮质，并通过角束终止主要在内侧基底核和外侧基底核，与较轻的终止在外侧核，杏仁核周围皮质，和皮质过渡区。这些杏仁核的输入大多数来自嘴侧海马结构，虽然有一个额外的投影从尾侧海马中央核的证据模棱两可。许多杏仁核的投射终止于杏仁-海马区的分子层和海马钩回部分的相邻分子层。辅助基底，外侧基底，和内侧基底核也投射到最喙部的地层moleculare领域CA 1 -3，最重的终止发生在现场CA 3。额外的预测从基底核终止于prosubiculum，presubiculum，和parasubiculum。最重的内嗅输入产生的附件基底和侧核和终止于层I，II和III的区域28 B，28 I，和前嗅皮质。杏仁核传入嗅周皮质的主要神经元来自外侧基底核。
The interconnections between the amygdala and the hippocampal formation were investigated in the macaque monkey using anterograde tracers. The hippocampal inputs to the amygdala arose from the subicular and entorhinal cortices and passed through the angular bundle to terminate principally in the medial basal and lateral basal nuclei, with lighter termination in the lateral nucleus, the periamygdaloid cortex, and the cortical-transition area. The majority of these amygdaloid inputs arose from the rostral hippocampal formation although there were equivocal evidence of an additional projection from the caudal hippocampus to the central nucleus. Projections arose from many of the amygdaloid nuclei to terminate in the molecular layer of the amygdalo-hippocampal area and the adjacent stratum moleculare of the uncal portion of the hippocampus. The accessory basal, lateral basal, and medial basal nuclei also projected to the most rostral portions of the stratum moleculare of fields CA1-3, the heaviest termination occurring in field CA3. Additional projections from the basal nuclei terminated in the prosubiculum, presubiculum, and parasubiculum. The heaviest entorhinal inputs arose from the accessory basal and lateral nuclei and terminated in layers I, II, and III of areas 28b, 28i, and the prorhinal cortex. The major amydaloid input to the perirhinal cortex arose from the lateral basal nucleus.
