Spaceflight cognitive testing using MRI brain scans
Part of Brain & nervous system clinical trials.
This study looks at how long-duration space travel affects thinking skills, especially memory and spatial navigation, and what changes happen in the brain. It compares astronauts with healthy volunteer “astronaut surrogates” and uses MRI scans to measure brain function.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be an astronaut (per NASA rules) or a healthy volunteer matched by age, sex, and education.
- You must be able to complete the MRI testing as required.
- No MRI safety issues like a pacemaker/defibrillator or other non-removable metal in your body.
- You cannot be pregnant, or possibly pregnant.
- No history of certain prior brain or heart surgeries.
- You must be able to safely undergo MRI even if you have hearing issues (for example, severe hearing loss) or certain implanted devices.

Other trials that look related to this one.
This study looks at how blood flow in the brain changes while you are thinking. You will do tasks while having brain scans to help researchers understand normal brain activity.
This study looks at how the stress of spaceflight affects the brain and behavior. You will complete tasks and have MRI scans while staying in a controlled environment, including some sleep disruption and alcohol consumption.
This research study tests new ways to take detailed pictures of your brain using MRI (a safe imaging machine). You'll help researchers develop better imaging methods by lying still in the scanner for up to 2 hours.
This study uses MRI scans to check and improve how medical teams measure brain changes. If you’re eligible, you’ll complete MRI safety screening and imaging while the team studies which scan measurements work best.
This study tests how people learn from choices and make decisions using computer tasks. Some participants also complete brain scans (MRI) to see how the brain activity matches behavior.
This study looks at how your brain's electrical activity relates to its structure using safe, non-invasive techniques (TMS, EEG, and MRI). It's a chance to learn more about how the healthy brain works, and you'll be asked to have brain scans and a mild stimulation session.
