NCT ID NCT02719951
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study used special PET and MRI scans to look at brain activity in 27 men with autism, Fragile X syndrome, or no condition. The goal was to measure a brain chemical called glutamate, which helps nerve cells communicate. Researchers hope this will reveal how brain signaling differs in these conditions.
