杏仁核在心血管功能的高级控制中很重要。在这项研究中，我们比较了杏仁核亚核之间的心血管相关的预测。将生物素化葡聚糖胺注射到杏仁核的中央、内侧和基底外侧核，分析顺行标记终末终扣的分布和密度。我们发现内侧核、基底外侧核和中央核都有投射到下丘脑心血管相关区。然而，只有中央核有一个显着的直接投射到延髓。与此相反，内侧核的投射有限，基底外侧核没有延伸到延髓的终末。我们的结论是，内侧，中央和基底外侧核的杏仁核可能会影响心血管相关核通过单突触连接与下丘脑和延髓的心血管相关核。(C)2013 Elsevier B.V.保留所有权利。
The amygdala is important in higher-level control of cardiovascular functions. In this study, we compared cardiovascular-related projections among the subnuclei of the amygdala. Biotinylated dextran amine was injected into the central, medial, and basolateral nuclei of the amygdala, and the distributions and densities of anterograde-labeled terminal boutons were analyzed. We found that the medial, basolateral, and central nuclei all had projections into the cardiovascular-related areas of the hypothalamus. However, only the central nucleus had a significant direct projection into the medulla. By contrast, the medial nucleus had limited projections, and the basolateral nucleus had no terminals extending into the medulla. We concluded that the medial, central, and basolateral nuclei of the amygdala may influence cardiovascular-related nuclei through monosynaptic connections with cardiovascular-related nuclei in the hypothalamus and medulla.
