Navigating the spectral slopes of the NSRR cohorts

Nataliia Kozhemiako & Shaun Purcell We recently used NSRR data to study the so-called spectral slope of the electroencephalogram (EEG), during wake, NREM and REM sleep. This work (described in a bioRxiv pre-print, Kozhemiako et al.) points to the power of NSRR data: thousands of polysomnographic studies that can be rapidly and freely repurposed to address a broad array of research questions.

The NSRR Cohort Matrix: An easier way to explore the NSRR datasets

The NSRR is constantly developing new tools to improve its user experience. One of the newly developed applications, as inspired by the Dementias Platform, is the Cohort Matrix. The NSRR cohort matrix consists of three tabs: "Cohort Overview" tab provides summary of the key characteristics (e.g. sample size, age range, license, etc.), sleep data availability (e.g. polysomnography EDF files, actigraphy, etc.) and links back to the dataset introduction page.
