The Sleep and Chronophysiology Laboratory

The Sleep and Chronophysiology Laboratory at the University of Michigan is a research facility that investigates sleep and biological rhythm regulation from childhood through adulthood using electroencephalogram (EEG) to measure brain activity. We have a strong interest in the biological risk factors for depression and how major depressive disorder affects the sleep of both children and adults.

Insomnia and biological rhythm problems are a focus of our clinical service. Most of our studies require a minimum of two overnight sleep studies. Our laboratory is equipped with 8 bedrooms, shower facilities, kitchen with microwave and stove-top, and a very comfortable environment conducive for sleeping away from home.

Two research projects currently being studied at the Sleep Laboratory are in critical need of participants. Please read the brief descriptions and visit their Web listings for additional information or to sign-up.

Sleep Differences in Depressed Teens
The purpose is to determine how depression and gender affects sleep in adolescence, and how delaying bedtime affects sleep regulation. This study, funded by the National Institutes of Health, is seeking teens between 13 and 18, with or without depression.

Managing Sleep and Medication Therapy to Improve Depression Treatment Response
The purpose is to determine if reducing the amount of nightly sleep while taking an approved medication therapy for depression is safer and more effective than the medication with no sleep reduction. This study is seeking adults between 20 and 40, with depression who are not currently receiving medication for their illness or are in the process of being weaned off medication. Patients can be in behavioral or talk therapy.
