Scientists from the University of Zurich recently carried out a study to understand how different methods of inducing altered states of consciousness appear in the brain. The study used brain scans from 107 people and found that the methods — meditation, hypnosis, and psychedelics — caused different changes and reactions, even though people might feel similar experiences from one to the next. The study’s goal is to realize the specific benefits of treatments for various mental health issues, especially those who haven’t found success with existing therapies.
