We have identified a generalized arousal component in the behavior of mice. Analyzed by mathematical/statistical approaches across experiments, investigators, and mouse populations, it accounts for about 1/3 of the variance in arousal-related measures. Knockout of the gene coding for the classical estrogen receptor (ER-alpha), a ligand-activated transcription factor, greatly reduced arousal responses. In contrast, disrupting the gene for a likely gene duplication product, ER-beta, did not have these effects. A combination of mathematical and genetic approaches to arousal in an experimentally tractable mammal opens up analysis of a CNS function of considerable theoretical and practical significance.
我们已经在小鼠行为中识别出一种全身性觉醒成分。通过跨实验、研究者和小鼠群体的数学/统计方法分析,它约占觉醒相关测量指标中变异的三分之一。编码经典雌激素受体(ER-α,一种配体激活转录因子)的基因敲除极大地降低了觉醒反应。相比之下,破坏一种可能是基因复制产物ER-β的基因则没有这些作用。在一种实验上易于处理的哺乳动物中,采用数学和遗传学方法相结合来研究觉醒,开启了对具有相当理论和实际意义的中枢神经系统功能的分析。
