Serial paraffin sections of hagfish brain (Eptatretus burgeri) were immunocytochemically examined for porcine neurophysin (NEU), arg-vasopressin (AVP) and oxytocin (OT). A big number of NEU-immunoreactive nerve cells were visible in the frontal part of the ventromedial hypothalamus in close vicinity of the third ventricle. These cells were bipolar in most cases and sometimes additionally stained for AVP but not for OT. NEU-reactive neurons extended axons to the median eminence and the posterior lobe of the pituitary which also contained AVP or OT-like immunoreactivity. Immunostaining outside the hypothalamus could not be observed. It is likely that there exists a mammalian-like oxytocinergic and a vasopressinergic hypothalamo-neurohypophysial system in hagfish, despite the large differences in levels of organization.
对盲鳗（蒲氏黏盲鳗）脑的系列石蜡切片进行免疫细胞化学检测，以检测猪神经垂体素（NEU）、精氨酸加压素（AVP）和催产素（OT）。在第三脑室附近的腹内侧下丘脑前部可见大量NEU免疫反应性神经细胞。这些细胞大多为双极细胞，有时还额外被AVP染色，但不被OT染色。NEU反应性神经元的轴突延伸至正中隆起和垂体后叶，垂体后叶也含有AVP或OT样免疫反应性。未观察到下丘脑外的免疫染色。尽管在组织结构水平上存在很大差异，但盲鳗中可能存在类似哺乳动物的催产素能和加压素能下丘脑 - 神经垂体系统。
