Join Our Sleep Study: Help Us Unlock the Mysteries of the Sleeping Brain!

Who are we?

The Center for Human Sleep Science is a cognitive neuroscience lab located at the University of California, Berkeley, in association with the Helen Wills Neuroscience Institute and the Henry H. Wheeler Jr. Brain Imaging Center.


Directed by Dr. Matthew Walker, research in the lab focuses on the role of sleep on human brain function, and how we can improve our sleep to enhance different facets of our overall well-being.

Who are we looking for?

Healthy adults aged 60 years or older

Residents currently living within two hours (~ 100 miles) of the Bay Area

No previous sleep disorder diagnosis other than Sleep Apnea

No major neurological and/or psychiatric disorders

What is this study about?

The Longitudinal Aging and Sleep Study (LASS) investigates sleep and cognitive changes within the brain of healthy older adults (60+ years). Additionally, we explore how these changes may intersect with normal aging. Our lab works closely with other UC Berkeley research labs to study these effects.

Please note: This research study does not provide clinical assessments or opinions to individual participants. 

How are we studying the brain?

Wrist Actigraphy

A watch used to understand your sleep-wake pattern by tracking body motion throughout the day. 

Questionnaires & Cognitive Assessments

Paper and computer tasks that 

assess your sleep, mood, and memory.


A non-invasive measurement of physiological variables such as heart rate, blood pressure, respiration, and electrical brain activity.

Magnetic Resonance Imaging (MRI)

A non-invasive medical imaging technique using magnetic fields to obtain images of the brain.
