Ketamine or saltwater? stanford study probes Sedation's hidden effects

This study at Stanford University tests whether adding ketamine to standard sedation changes the experience of people with major depressive disorder. Fifteen healthy volunteers will receive both ketamine and saline (saltwater) during separate sedation sessions, without knowing which they got. The goal is to see if ketamine affects dream reports, brain activity, or short-term mood. This is an early-phase study focused on understanding, not treatment.
