Great progress is being made on understanding exactly how sex steroids act on the nervous system to yield adaptive behavior and physiology that serves to promote reproductive success. Dr. Adkins-Regan is performing experiments on birds which investigates the spinal level neuroendocrine processes. This work will contribute to our understanding of the role of testosterone metabolites in androgenic actions on the nervous system. Dr. Adkins-Regan has data that show that these sex steroids change the dendritic arborizations of motor neurons. This finding has ramifications for neuronal plasticity in the adult. This work is important because there is increasing recognition that in addition to specific reproduction related effects on the nervous system such as the production of sexual dimorphism, sex hormones may have more general trophic effects on neural development. Neuroendocrinology is a tremendously fast moving field, and its study should yield many new findings regarding the physiology of human behavior.

在了解性是如何 类固醇作用于神经系统产生适应行为 以及促进繁殖成功的生理学。 阿德金斯-里根博士正在对鸟类进行实验， 研究脊髓水平的神经内分泌过程。 这 工作将有助于我们理解的作用， 睾酮代谢物对神经系统的雄激素作用 系统 阿德金斯-里根博士的数据显示， 类固醇改变运动神经元的树突分支。 这一发现对大脑中神经元的可塑性有着重要的影响。 成年人了 这项工作很重要，因为有越来越多的 认识到，除了与生殖有关的具体问题外， 对神经系统的影响，如性功能的产生， 两性异形，性激素可能具有更普遍的营养作用 关于神经发育 神经内分泌学是一个非常重要的 快速移动的领域，它的研究应该产生许多新的发现 关于人类行为的生理学
