In 1999 the GCRC was funded for the renovation of inpatient rooms for Sleep Research and in 2000 funding was provided for personnel and equipment. The GCRC Sleep Laboratory consists of three fully equipped sleep bedrooms and an adjacent control room for monitoring these patients. Each bed is equipped with state-of-the-art EMBLA polysomnographic recording units, and are configured for continuous sampling of the physiologic signals required for polysomnographic recordings. In addition, two of the beds are have the capability for intermittent venous blood sampling that can be conducted without disrupting patients from sleep. Research nursing and technical support are also available.

Recordings performed in the GCRC sleep facility are currently analyzed at the Johns Hopkins Sleep Disorders Center. This is a contemporary unit located on the fourth floor of the Asthma and Allergy Center (adjacent to the building housing the GCRC facility). Microcomputer-based laboratory workstations are available and have specialized software installed to assist in scoring polysomnographic recordings. Once these recordings are scored, results are data based and reports are generated for review by the sleep core and investigative team. The database is housed on a server in the GCRC that can be accessed from multiple workstations in the center. By 2004, a polysomnographic scoring workstation on the GCRC will be available for investigators to review polysomnographic recordings and summary data directly through an investigator-friendly database as part of GCRC Informatics Core resource.
