The efferents connections of the area postrema (AP) have been studied autoradiographically following iontophoretic injections of 3H-glycine or 3H-leucine into the area postrema. Precise control of the diffusion of the labelled amino acids injected iontophorectically into the AP was made using the technique of sectioning with a cryostat. AP projects to a great number of structures. Projections to nucleus tractus solitarius (NFS), dorsal vagal nucleus, nucleus intercalatus, nucleus praepositus hypoglossi, nucleus hypoglossal, the mesencephalic nucleus of V nerve, locus coeruleus and superior and inferior colliculi are shown bilaterally. The density of the efferents was greatest to the NFS and the LC. Corelations are suggested with functional mechanisms of cardiovascular regulation.
在将³H - 甘氨酸或³H - 亮氨酸离子导入延髓后区（AP）后，通过放射自显影术研究了延髓后区的传出连接。使用低温恒温器切片技术精确控制离子导入AP的标记氨基酸的扩散。延髓后区投射到大量结构。双侧显示投射到孤束核（NFS）、迷走神经背核、中间核、舌下前置核、舌下神经核、三叉神经中脑核、蓝斑以及上丘和下丘。传出纤维密度在孤束核和蓝斑中最大。提示与心血管调节的功能机制有关。
