The distribution of vasopressin (VP)-like and oxytocin (OX)-like immunoreactivities was investigated in the chameleon brain with antisera specific for either peptide. VP-like and OX-like neurons are found only in two nuclei: in the supraoptic and in the paraventricular nuclei, whereas both peptidergic innervations are restricted to some ventral areas, especially to the hypothalamus. However, in these areas, OX-like innervation is less dense than the VP-like innervation. Even though, no sex differences were noted for the two systems, differences are present between the normal female and the preoviposit one concerning VP-like system. In the latter female, numerous VPergic-like cell bodies occurred in the ependymal layer, making likely direct contact with the cerebrospinal fluid (CSF) of the third ventricle. In addition, some VP-like nerve fibers seem to be in supraependymal position at the septal wall, probably also in contact with CSF.
利用针对这两种肽的抗血清，研究了变色龙脑中加压素（VP）样和催产素（OX）样免疫反应性的分布。仅在两个核中发现了VP样和OX样神经元：视上核和室旁核，而两种肽能神经支配都局限于一些腹侧区域，尤其是下丘脑。然而，在这些区域，OX样神经支配比VP样神经支配密度低。尽管这两个系统未发现性别差异，但正常雌性和产卵前雌性在VP样系统方面存在差异。在后者的雌性中，许多VP能样细胞体出现在室管膜层，可能与第三脑室的脑脊液（CSF）直接接触。此外，一些VP样神经纤维似乎位于隔壁的室管膜上位置，可能也与脑脊液接触。
