This study looked at how cooling the brain changes its response to magnetic stimulation. Healthy adults wore a cooling cap while researchers measured brain activity with TMS and EEG. The goal was to better understand brain plasticity, not to treat any disease.

This study looked at how certain brain receptors (dopamine D1 and D2/3) work in people with schizophrenia compared to healthy volunteers. Researchers used special PET and MRI scans to measure these receptors. The goal was to learn more about what causes schizophrenia, which could…

This study used advanced brain scans (MRI and MEG) to compare the brains of over 3,000 people with schizophrenia and healthy volunteers. The goal was to find differences in brain structure, chemistry, and activity that could help explain schizophrenia. No treatments or medication…

This study looked at how the brain works in people with schizophrenia when they are not taking medication. Researchers used brain scans and tests to separate the effects of the illness from the effects of the drugs. Participants stayed in the hospital for safety while their medic…

This study looked at women with PMS to better understand their symptoms. Researchers used interviews, daily mood ratings, and hormone tests to describe the condition. A smaller group with severe PMS (PMDD) was offered extra studies on hormone changes, treatments, and genetics. Th…

This study tested different ways to apply non-invasive brain stimulation (like magnetic pulses) in 83 healthy adults aged 18-65. The goal was to learn how to make these techniques more effective for diagnosing and treating brain disorders. Participants completed tasks, had brain …

This study used PET scans to look at dopamine and blood flow in the brains of healthy people, people with Parkinson's disease, and those with schizophrenia. The goal was to understand how dopamine problems differ between these conditions. Over 500 participants took part, but no t…
