The specificity and topographic organization of afferent projections to the intermediolateral column (IML) were examined using retrograde transport of fluorescent tracers injected into pairs of thoracic spinal segments. Neurons within the hypothalamus (parvocellular paraventricular nucleus, dorsomedial nucleus and lateral hypothalamus), pons (Kolliker-Fuse and A5 nuclei) and medulla (ventrolateral nucleus of the solitary tract and rostral ventrolateral medulla) each appeared to innervate only a single spinal segment. Neurons in each cell group projecting to different spinal segments were intermixed and showed no evidence of topographic organization. These results provide a potential anatomical substrate for organ-specific autonomic responses to physiological and psychological stimuli.
利用向成对胸段脊髓节段注射荧光示踪剂的逆行运输法，研究了传入至中间外侧柱（IML）投射的特异性和拓扑组织。下丘脑（小细胞室旁核、背内侧核和外侧下丘脑）、脑桥（柯利克-富斯核和A5核）和延髓（孤束核腹外侧核和延髓头端腹外侧）内的神经元似乎各自仅支配单个脊髓节段。投射至不同脊髓节段的每个细胞群中的神经元相互混合，未显示出拓扑组织的证据。这些结果为对生理和心理刺激的器官特异性自主反应提供了潜在的解剖学基础。
