在金黄仓鼠中，下丘脑前部微量注射精氨酸加压素（AVP）会触发刻板的气味标记行为，即侧翼标记。我们的实验是为了测试在控制这种行为的视交叉上核（SCN）内的AVP神经元的贡献。我们的研究结果表明，SCN不有助于侧翼标记行为。而SCN病变破坏了昼夜节律的车轮运行，同样的病变并没有破坏侧翼标记。结果还表明，位于SCN外的神经元对脑的加压素能神经支配和AVP依赖性行为的表达，如侧翼标记行为有显着贡献。虽然AVP免疫反应纤维严重（约。95%）从SCN损伤的仓鼠的几个前脑区域耗尽，损伤的影响在涉及侧腹标记行为的前脑区域内以及在中脑和后脑内更加有限。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
In golden hamsters, microinjections of arginine-vasopressin (AVP) within the anterior hypothalamus trigger a stereotyped scent-marking behavior, flank marking. Our experiment was carried out to test the contribution of AVP neurons within the suprachiasmatic nucleus (SCN) in the control of this behavior. Our results suggest that the SCN does not contribute to flank-marking behavior. Whereas SCN lesions disrupted circadian rhythms of wheel running, the same lesions did not disrupt flank-marking. The results also suggest that neurons located outside the SCN contribute significantly to the vasopressinergic innervation of the brain and the expression of AVP-dependent behaviors, such as flank-marking behavior. Although AVP-immunoreactive fibers were severely (ca. 95%) depleted from several forebrain areas in SCN-lesioned hamsters, the effect of the lesions was much more limited within the forebrain areas involved in flank-marking behavior as well as within the midbrain and hindbrain.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
