Hemodynamic Correlates of Distinct Hypnotic States

The hypnosis intervention consists of two elements: A hypnotic induction and a hypnotic deepening. The induction aims at guiding the participant into the first hypnotic state (state 1). The participants will remain in this state for 10 minutes, the duration of the fMRI-scan. The hypnotic deepening guides the participants into a very deep hypnotic state (state 2). Participants also remain in this state for 10 minutes, during which their brain activity is measured using fMRI

The control intervention consists of texts corresponding to the induction and deepening of the hypnosis intervention. They are matched in duration and consist of textually matched excerpts from www.wikipedia.org. Control induction will be presented, resulting in the control state 1 (10 min). Then the control deepening will be performed, leading to the control state 2 (10 minutes). During both control states the brain activity will be recorded using fMRI.
