用辣根过氧化物酶（HRP）逆行追踪法，研究了大鼠和猫丘脑向杏仁核的投射。HRP注射立体定向微离子导入在各个杏仁核。进行了几种控制程序，包括使用不同的方法引入微量移液器，以消除由于相邻结构或纤维摄取蛋白质而导致误解的可能性。丘脑的室旁核和副丘脑核投射到整个杏仁复合体。内侧膝状体复合体和腹内侧复合体的基底核（丘脑味觉中继）主要投射到杏仁核的中央内侧部。基底外侧核是一个迄今未描述的双边丘脑-杏仁通路起源于前内侧核的主要接受者。束旁核投射到杏仁核的中央核;猫主要投射到中央核的外侧亚核。研究结果进行了讨论，与以前的解剖和电生理研究集中在杏仁复合体。特别提到的可能作用的丘脑-杏仁核的连接在传递感官信息的杏仁核。
By the use of the retrograde transport of horseradish peroxidase (HRP), the projections from the thalamus to the amygdala were investigated in the rat and cat, with main emphasis on the former species. HRP was injected stereotactically by microiontophoresis in the various amygdaloid nuclei. Several control procedures including the use of different approaches for the introduction of the micropipette were undertaken to eliminate the possibility of misinterpretation due to uptake of the protein by adjacent structures or fibers en passant. The paraventricular and parataenial nuclei of the thalamus projected throughout the entire amygdaloid complex. The medial geniculate complex and the basal nucleus of the ventromedial complex (the thalamic taste relay) mainly project to the centromedial part of the amygdala. The basolateral nucleus is the main recipient of a hitherto undescribed bilateral thalamo-amygdaloid pathway originating in the interanteromedial nucleus. The parafascicular nucleus projects to the central nucleus of the amygdala; in the cat mainly to the lateral subdivision of the central nucleus. The findings are discussed in relation to previous anatomical and electrophysiological studies centered on the amygdaloid complex. Special reference is made to the possible role of the thalamo-amygdaloid connections in the conveyance of sensory information to the amygdala.
