用辣根过氧化物酶研究了灵长类动物杏仁核的传入投射。这种技术的潜在优势进行了讨论与以前用于确定杏仁传入。某些无颗粒或颗粒异常的皮质区域可能直接投射到杏仁核：特别是眶额皮质、前扣带回、胼胝体下回、颞极和前扣带回。这些预测可能主要终止于外侧或副基底核。其他皮质预测从颞下和上级颞回的描述。从上级颞沟到外侧核有明显的突起。皮质下传入纤维来自下丘脑、无名质、斜角带、丘脑、中脑导水管周围中央灰质、脚周核和从脚周核向中线内侧延伸的一条细胞带，就在丘脑腹侧。在丘脑，标记细胞仅限于非特异性核团，并常见于嘴侧中线核团。丘脑背内侧核无投射。解释杏仁核的功能的影响进行了讨论。
The afferent projections to the primate amygdala were studied using horseradish peroxidase. The potential advantages of this technique are discussed compared with those previously used to determine amygdaloid afferents. Certain agranular or dysgranular cortical regions may project directly to the amygdala: in particular, the orbital frontal cortex, anterior cingulate gyrus, subcallosal gyrus, temporal pole and anterior insula. These projections probably terminate predominantly in the lateral or accessory basal nuclei. Other cortical projections from the inferotemporal and superior temporal gyri are described. Evidence was found for a heavy projection from the superior temporal sulcus to the lateral nucleus. Subcortical afferents were found from the hypothalamus, substantia innominata, diagonal band, thalamus, periaqueductal central gray, peripeduncular nucleus and from a band of cells extending medially from the peripeduncular nucleus to the midline, just ventral to the thalamus. In the thalamus, labeled cells were restricted to the non-specific nuclei, and were common in the rostral midline nuclei. No projection was observed from the dorsomedial nucleus of the thalamus. Implications for interpreting the functions of the amygdala are discussed.
