Summary

This study looks at how two common anesthesia drugs, ketamine and propofol, change brain activity related to memory and pain. Healthy adults aged 18-59 will have MRI scans and EEG recordings while receiving the drugs alone or together. The goal is to understand brain connectivity, not to treat any condition.
