National Sleep Research Resource
The National Sleep Research Resource offers free access to large collections of de-identified physiological signals and clinical data elements collected in well-characterized research cohorts and clinical trials.
The NSRR encourages interested researchers, educators, and trainees to join its community. Members can contribute their own data and tools for sharing, provide information and feedback on ways to improve sleep and physiological signal data exchange and analysis, and offer ideas on how to make NSRR and other resources work best for the scientific community.
PhysioNet provides access to large and diverse collections of recorded physiologic signals and related open-source software. PhysioNet currently includes over 200 annotated polysomnograms in 4 collections, and more than 60 other databases, including the MIMIC and MIMIC II Waveform and Clinical Databases collected from over 30,000 ICU patients, and a wide range of specialized data sets from clinical and research studies.
