- Sleep & EEG Core
Dear Core User,
Due to the current situation with COVID-19, per directives from Senior management at Partners and the Hospitals, this research core facilities will have a hiatus in their service offering. We will not be offering service till we are advised to resume operation.
Please stay safe in this challenging time and we look forward to working with you in the future.
Sleep & EEG Core
The Sleep & EEG Core within the Division of Sleep and Circadian Disorders (DSCD) provides an integrated infrastructure and knowledge base in support of research projects that use polysomnography (PSG), quantitative EEG analysis and related methodologies. The Core consists of a team of specialists lead by the Core director and a chief PSG technologist.
The Core provides support and services in different areas:
1) It provides basic training and certification in PSG and EEG instrumentation to technicians and investigators, particularly those conducting studies at the Center for Clinical Investigation (CCI) at Brigham and Women’s Hospital.
2) It acts as liaison between DSCD investigators and CCI technical staff, and implements and monitors quality assurance measures.
3) It carries out standard vigilance state scoring of PSG recordings and different types of waking EEG and electrooculogram analyses.
4) It carries out spectral analysis of sleep and waking EEG.
5) It evaluates, acquires, and maintains PSG and EEG equipment used by investigators of the CCI.
6) It carries out PSG procedures such as sleep screens and multiple sleep latency tests.
7) It assists investigators in the analysis and interpretation of sleep and EEG data.
Over the years, the Sleep & EEG Core has been a central part of many projects funded by NIH, the Air Force Office of Scientific Research (AFOSR), and the National Space Biomedical Research Institute (NSBRI) that had a main focus on the physiology of human sleep-wake regulation. Scientifically, the Core has contributed by providing investigators with important quantitative measures of homeostatic and circadian components of the human sleep-wake regulatory system.
