The first issue of Hormones and Behavior was published 50 years ago in 1969, a time when most of the techniques we currently use in Behavioral Endocrinology were not available. Researchers have during the last 5 decades developed techniques that allow measuring hormones in small volumes of biological samples, identify the sites where steroids act in the brain to activate sexual behavior, characterize and quantify gene expression correlated with behavior expression, modify this expression in a specific manner, and manipulate the activity of selected neuronal populations by chemogenetic and optogenetic techniques. This technical progress has considerably transformed the field and has been very beneficial for our understanding of the endocrine controls of behavior in general, but it did also come with some caveats. The facilitation of scientific investigations came with some relaxation of methodological exigency. Some critical controls are no longer performed on a regular basis and complex techniques supplied as ready to use kits are implemented without precise knowledge of their limitations. We present here a selective review of the most important of these new techniques, their potential problems and how they changed our view of the hormonal control of behavior. Fortunately, the scientific endeavor is a self-correcting process. The problems have been identified and corrections have been proposed. The next decades will obviously be filled with exciting discoveries in behavioral neuroendocrinology.

在过去的50年中,技术进步如何重塑了行为神经内分泌学……以及一些方法论上的评论。

《激素与行为》的第一期于50年前的1969年出版,当时我们目前在行为内分泌学中使用的大多数技术都不可用。在过去的五十年中,研究人员开发了多种技术,可用于测量少量生物样品中的激素,识别类固醇在大脑中激活性行为的位点,表征和量化与行为表达相关的基因表达,在特定的条件下修饰该表达方式,并通过化学遗传学和光遗传学技术操纵选定的神经元群体的活动。这项技术进步极大地改变了该领域,并且对我们了解内分泌对行为的总体控制非常有益,但也有一些警告。科学研究的便利伴随着方法上的紧急性的放松。不再定期执行一些关键控制,并且在没有确切了解其局限性的情况下实施了随用套件所提供的复杂技术。在这里,我们将对这些新技术中最重要的新技术,它们的潜在问题以及它们如何改变我们对荷尔蒙控制行为的看法进行选择性回顾。幸运的是,科学的努力是一个自我纠正的过程。已发现问题并提出了纠正措施。在接下来的几十年中,行为神经内分泌学将充满激动人心的发现。不再定期执行一些关键控制,并且在没有确切了解其局限性的情况下实施了随用套件所提供的复杂技术。在这里,我们将对这些新技术中最重要的新技术,它们的潜在问题以及它们如何改变我们对荷尔蒙控制行为的看法进行选择性回顾。幸运的是,科学的努力是一个自我纠正的过程。已发现问题并提出了纠正措施。在接下来的几十年中,行为神经内分泌学将充满激动人心的发现。不再定期执行一些关键控制,并且在没有确切了解其局限性的情况下实施了随用套件所提供的复杂技术。在这里,我们将对这些新技术中最重要的新技术,它们的潜在问题以及它们如何改变我们对荷尔蒙控制行为的看法进行选择性回顾。幸运的是,科学的努力是一个自我纠正的过程。已发现问题并提出了纠正措施。在接下来的几十年中,行为神经内分泌学将充满激动人心的发现。幸运的是,科学的努力是一个自我纠正的过程。已发现问题并提出了纠正措施。在接下来的几十年中,行为神经内分泌学将充满激动人心的发现。幸运的是,科学的努力是一个自我纠正的过程。已发现问题并提出了纠正措施。在未来的几十年中,行为神经内分泌学将显然充满激动人心的发现。
