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. The findings indicate that 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 either 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, labelled 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. We discuss the implications of these results for interpreting the functions of the amygdala.
使用辣根过氧化物酶对灵长类动物杏仁核的传入投射进行了研究。与先前用于确定杏仁核传入纤维的技术相比，讨论了该技术的潜在优势。研究结果表明，某些无颗粒或颗粒减少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、颞极和前岛叶。这些投射可能主要终止于外侧核或副基底核。还描述了来自颞下回和颞上回的其他皮质投射。发现有大量纤维从上颞沟投射到外侧核。发现了来自下丘脑、无名质、斜角带、丘脑、导水管周围中央灰质、脚周核以及从脚周核内侧延伸至中线（恰好在丘脑腹侧）的一条细胞带的皮质下传入纤维。在丘脑中，标记细胞局限于非特异性核，并且在吻侧中线核中很常见。未观察到来自丘脑背内侧核的投射。我们讨论了这些结果对解释杏仁核功能的意义。
