研究了雄性仓鼠的终神经或终神经在信息素诱导的睾酮激增中的作用。研究人员从没有接触到气味（基线）的雄性仓鼠身上采集血液，然后在一周后从同样的仓鼠身上采集血液，这些仓鼠暴露在一只发情的雌性的阴道分泌物气味中。进行末梢神经病变、前脑病变或假手术，并在有或没有气味刺激的情况下再次采血。用放射免疫法测定血清睾酮水平。在暴露于发情的雌性仓鼠的气味后，所有的手术过程都没有中断雄性仓鼠显示血清睾酮增加的能力。我们的结论是，末梢神经在这种信息素介导的神经内分泌反射中不是必需的。
The involvement of the nervus terminalis or terminal nerve in the pheromonally induced testosterone surge in the male hamster was investigated. Blood was collected from male hamsters not exposed to odor (baseline), and then a week later from the same hamsters exposed to the odor of vaginal discharge from an estrous female. Terminal nerve lesions, forebrain lesions, or sham surgeries were performed, and blood was collected again with and without odor stimulation. Serum testosterone levels were assessed by radioimmunoassay. None of the surgical procedures interrupted the ability of the male hamsters to demonstrate an increase in serum testosterone following exposure to the odor of an estrous female. We conclude that the terminal nerve is not necessary for this pheromonally mediated neuroendocrine reflex.
