The Phylogeny of Sleep Database

We have constructed a database that describes the sleeping characteristics of 127 different mammalian species representing 46 families across 17 orders. The data were extracted from 178 separate references that were found using standardized search protocols, and for each study includes information on the time spent in REM and NREM sleep, sleep cycle length, the number of animals sampled, their sex and age, and reference citation. Importantly, we also coded nine laboratory condition scores as a way to control for the procedures that were used to collect the data.我们构建了一个数据库，用以描述隶属于17个目、46个科的127种不同哺乳类动物的睡眠特征。该数据集通过标准化检索流程从178篇独立文献中提取得到，每项纳入研究的相关信息均包含快速眼动睡眠（REM）与非快速眼动睡眠（NREM）的时长、睡眠周期长度、采样动物数量、受试动物的性别与年龄，以及参考文献引文。尤为关键的是，我们还对9项实验室条件评分进行了编码，以此对数据采集所采用的实验流程进行控制，以消除不同实验范式带来的混杂影响。
