最近使用电生理学和神经解剖学方法对内脏感觉系统的研究表明，中枢神经系统的各个层面都存在多种内脏模式的表现。在孤束核中，味觉传入在喙部，一般内脏传入在尾部。在桥脑中继处，臂旁核、味觉传入神经位于内侧，一般内脏传入神经位于外侧。尽管下丘脑和杏仁核的内脏投射的解剖学分离证据不完整，但内脏感觉丘脑和皮层是内脏组织的。结果表明，上行内脏感觉系统在大脑的各个层面上都是内脏组织的，并且该信息对于神经轴各个层面的自主反应的整合非常重要。
Recent studies of the visceral sensory system, using both electrophysiological and neuroanatomical methods, indicate that there is representation of multiple visceral modalities at all levels of the central nervous system. In the nucleus of the solitary tract gustatory afferents are represented rostrally, and general visceral afferents caudally. At the pontine relay, the parabrachial nucleus, the gustatory afferents are represented medially, and the general visceral afferents laterally. Although the evidence for anatomical separation of visceral projections is incomplete for the hypothalamus and amygdala, the visceral sensory thalamus and cortex are viscerotopically organized. The results indicate that the ascending visceral sensory system is viscerotopically organized at all levels of the brain, and that this information is important for the integration of autonomic responses at all levels of the neuroaxis.
