This observational study aims to better understand how different parts of the brain help us pay attention to what we see. Researchers are comparing people who have had damage to specific parts of their brain (like from a stroke or injury) with healthy volunteers. They want to see how these groups process visual information and how attention affects this process. The study will involve behavioral tasks and MRI scans to look at brain activity. The main goal is to identify which brain areas, particularly in the front and top-back parts of the brain, are involved in controlling our attention and how they influence what we see. This study does not test any specific drugs or interventions.

Study design

This is an observational study planning to enroll 300 participants. It compares individuals with focal brain lesions to healthy volunteers.

What's involved

You would have 4 to 10 visits to the NIH Clinical Center over 1 to 2 years. Each visit is expected to last about 2 hours.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoint, MRI signal, is measured at an ongoing basis, but the duration of follow-up is not specified beyond the 1-2 year study period.
