The present report describes the use of an antidromic mapping technique to define the extent and localisation of the afferent projections of the arterial baroreceptors and chemoreceptors to the medulla oblongata. There are distinct differences in their pattern of projection: baroreceptors project primarily laterally, chemoreceptors medially, to regions which are also innervated by lung stretch afferents. Baroreceptors, however, do project to medial regions of the nucleus tractus solitarius and the significance of these patterns of projection is discussed in relation to the respiratory modifications of the performance of the baroreceptor reflex. The diencephalic control of transmission of the baroreceptor reflex is also discussed in the light of the marked innervation that the nucleus tractus solitarius receives from cell groups in the diencephalon.
本报告描述了使用逆向映射技术来确定动脉压力感受器和化学感受器向延髓的传入投射的范围和定位。它们的投射模式存在明显差异：压力感受器主要向外侧投射，化学感受器向内侧投射，投射到的区域也由肺牵张传入神经支配。然而，压力感受器确实会投射到孤束核的内侧区域，并结合压力感受器反射活动的呼吸调节来讨论这些投射模式的意义。鉴于孤束核从间脑的细胞群接受显著的神经支配，还讨论了间脑对压力感受器反射传递的控制。
