Vanderbilt Sleep Research Core

Services

 

 

Actigraphy - Small non-intrusive watch-like devices used to measure sleep-wake patterns across periods of time.  

Centralized Sleep Data Management Site- Data collected in multicenter projects can be interpreted here at one centralized location to maintain consistency across all sites. Interaction between sites is essential for this process to work properly. Quality Assurance measures are used to aid all sites in data collection.     

Electroencephalography (EEG) – 21 lead full EEG commonly used to measure electrical activity of the brain. This service can be used in projects that have no relationship to sleep.  

Polysomnography (PSG) – Gold standard in objective sleep testing, measures brain waves, eye movements, muscle tone, heart rhythms, oxygen, respiratory effort, airflow, etc. Trial-specific measurement tools can be also used in conjunction with the standard PSG. 

Polysomnography Interpretation – PSG data must be interpreted in a reliable and consistent manner to allow for findings to be reproduced. This service allows for investigators who have little or no knowledge of interpreting PSG data to be able to obtain data in a useful manner.   

Portable Sleep Testing – Can be performed in settings outside of the lab, but lacks the level of reliability of the standard in lab PSG.
