ORBIT Brain Study


Brain imaging study of sleep’s effects on cognitive performance and brain activity in response to food cues

Study Type
fMRI
Study Purpose
This study is designed to assess whether long or short sleep duration influences the way the brain processes food cues and completes cognitive tasks.
Study Design
You will be asked to sleep 6 hours per night for 4 nights in a row and 9 hours per night for 4 nights in a row. Then, using brain imaging, specifically functional magnetic resonance imaging (fMRI) your brain will be scanned while looking at pictures of food and doing cognitive tests.
Study Requirements
To be eligible for this study you must be between the ages of 25-55, have a body mass index (BMI) between 25-40 kg/m2 and be able to have an MRI scan (e.g., no pacemakers or metal in the eyes)
Study Duration
Following an initial consenting and behavioral assessment session at the Weight Control & Diabetes Center, participants will be asked to follow a prescribed sleep schedule at home for 4 nights, and come to Brown University for an fMRI session. Participants will then have (at least) a 1-week ‘break’ in which there are no study requirements, followed by 4 more nights of following a prescribed sleep schedule at home and a second fMRI session.
Study Benefits
It is possible that you may experience some benefit from learning how your sleep affects your cognitive performance. Findings from this study may have important implications for the study of sleep duration and obesity. Participants will be compensated for their time.
