Characterization of Brain Morphology and Activity Using Functional and Anatomical MRI Contrast

What this Trial Is About

Researchers are evaluating new magnetic resonance imaging (MRI) techniques and hardware to better study brain function. This study focuses on improving the quality and detail of MRI scans to monitor blood flow and brain activity during simple tasks. The research aims to enhance understanding of both normal and abnormal brain behavior by using a more powerful MRI machine than those typically found in hospitals. Study participants are healthy volunteers aged 18 years and older who will undergo yearly MRI scans. During these scans, subjects lie on a stretcher moved into a strong magnetic field within a donut-shaped machine. A special coil device may be placed on the head to improve image quality. Scans last between 20 minutes and 3 hours, usually around 45 to 90 minutes. Participants may be asked to perform simple tasks such as listening to sounds, tapping fingers, or watching images while being scanned. During the study, participants will be evaluated through MRI scans combined with EEG and other physiological recordings to measure brain structure, chemistry, blood flow, and activity. The primary goal is to develop high-resolution anatomical and functional brain images. The study also tracks various brain tissue properties and compares different MRI techniques. Participants' involvement includes medical history review, neurological exams, and completing questionnaires to ensure safety and eligibility.
