About the Sleep and Chronophysiology Laboratory

The Sleep and Chronophysiology Laboratory is comprised of two separate laboratories: a conventional sleep laboratory and a state-of-the-art chronophysiology laboratory to study sleep and biological rhythms. The laboratories are housed within the Depression Center of the beautiful Rachel Upjohn Building. The building and the laboratories are secure after hours, with electronic card access to staff and faculty.

The primary Sleep Lab has 6 private bedrooms, a shared bathroom with shower, and a central control room.

In order to create a comfortable homelike environment, each bedroom has a twin bed with a high quality pillow top mattress, down-filled pillows and comforter (non-down alternatives are available for those with allergies), as well as an armoire for clothing and other belongings. All linens are 100 % cotton with a high thread count and professionally laundered. Each bedroom is temperature controlled, electromagnetically shielded and equipped with a fiber optic cable for data transmission and a call button to alert staff of any needs during the night.

The control room is equipped with 10 computers for data collection and processing, and has a folding acoustic partition which can split the sleep lab into two 3-bedroom labs. During the night, the control room is staffed by one or more research technicians who ensure the quality of data collection and comfort of research participants.

The chronophysiology laboratory is comprised of a control room and two suites. The control room has a kitchenette, intercoms for communicating with research participants in the suites, and computers for controlling the lights and for collecting and processing data. Each private suite has a bedroom, living room, and bathroom with shower. The bedrooms have double beds, bedside tables and clothing armoires. High quality mattresses and bed linens have been chosen for each suite. The living rooms are set up with a queen size sofa bed, coffee table, armchair, etc. Each suite is electromagnetically shielded, sound proof, isolated from building vibrations, and temperature controlled with separate controls for both its living room and its bedroom. Both of the living rooms and the bedrooms are equipped with fiber optic cables for data transmission, and the bedroom has a call button to alert staff of any needs during the night.

The living room has an advanced computer controlled light system which can recreate the brightness, color, and timing of sunlight (or artificial light) from any location on the earth, on any day of the year. This system makes it possible to create days that are longer or shorter than 24 hours, or 24 hours days that are synchronized with any time zone. It also holds great potential for exploring the use of bright light for treating depression and sleep disorders.

The Sleep and Chronophysiology also has kitchen, family interview room, and a workshop for repairing equipment.

The Sleep and Chronophysiology Laboratory uses portable battery-powered sleep EEG data acquisition systems that are capable of recording data in the laboratory or at remote sites such as the inpatient facilities at the University of Michigan Hospital.
