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.
最近利用电生理和神经解剖学方法对内脏感觉系统进行的研究表明，在中枢神经系统的各个层面都存在多种内脏感觉模式的表征。在孤束核中，味觉传入纤维在头侧，一般内脏传入纤维在尾侧。在脑桥中继核，即臂旁核，味觉传入纤维在内侧，一般内脏传入纤维在外侧。尽管下丘脑和杏仁核的内脏投射解剖学分离证据并不完整，但内脏感觉丘脑和皮层是按内脏部位组织的。结果表明，上行内脏感觉系统在大脑的各个层面都是按内脏部位组织的，并且这些信息对于神经轴各层面自主反应的整合很重要。
