Scientists use ketamine scans to unlock secrets of psychotic illness

This study aims to understand the brain mechanisms of psychosis to help develop better treatments for schizophrenia. Healthy volunteers receive a very low dose of ketamine while undergoing brain scans to measure how the drug affects brain activity. Researchers are testing different low doses to find the smallest amount that produces a measurable brain signal, which could serve as a tool for testing future medications. The study is currently suspended.
