Hypnosis in psychotherapy, psychosomatics and medicine. A brief overview.
Front Psychol
March 2024
MEG-Foundation, Wilhelmsthal-Hesselbach, Germany.
Article Synopsis
- Hypnosis has a rich 250-year history, evolving from early ideas like animal magnetism to play a role in psychotherapy, psychosomatics, and medicine, emphasizing imagination's importance in treatment.
- Concepts of the mind-body problem were explored in early romantic ideas of hypnosis, influencing modern understandings of unconscious processes and linking hypnosis to cognitive behavioral therapy techniques.
- Ongoing debates in social psychology question whether hypnosis is a unique state of consciousness or a normal interaction, with research showing that even moderately hypnotizable individuals can benefit and that factors like motivation and rapport are crucial for effective hypnotherapy.
Neuroscientific results of experimental studies on the control of acute pain with hypnosis and suggested analgesia.
Front Psychol

This narrative review summarizes a representative collection of electrophysiological and imaging studies on the neural processes and brain sources underlying hypnotic trance and the effects of hypnotic suggestions on the processing of experimentally induced painful events. It complements several reviews on the effect of hypnosis on brain processes and structures of chronic pain processing. Based on a summary of previous findings on the neuronal processing of experimentally applied pain stimuli and their effects on neuronal brain structures in healthy subjects, three neurophysiological methods are then presented that examine which of these neuronal processes and structures get demonstrably altered by hypnosis and can thus be interpreted as neuronal signatures of the effect of analgesic suggestions: (A) On a more global neuronal level, these are electrical processes of the brain that can be recorded from the cranial surface of the brain with magnetoencephalography (MEG) and electroencephalography (EEG).

Several theories of hypnosis assume that responses to hypnotic suggestions are implemented through top-down modulations via a frontoparietal network that is involved in monitoring and cognitive control. The current study addressed this issue re-analyzing previously published event-related-potentials (ERP) (N1, P2, and P3b amplitudes) and combined it with source reconstruction and connectivity analysis methods. ERP data were obtained from participants engaged in a visual oddball paradigm composed of target, standard, and distractor stimuli during a hypnosis (HYP) and a control (CON) condition.

Objective: To investigate the effect of therapeutic suggestions played to patients through earphones during surgery on postoperative pain and opioid use.
Design: Blinded randomised controlled study.
Setting: Five tertiary care hospitals in Germany.
Suggested deafness during hypnosis and simulation of hypnosis compared to a distraction and control condition: A study on subjective experience and cortical brain responses.

Hypnosis is a powerful tool to affect the processing and perception of stimuli. Here, we investigated the effects of hypnosis on the processing of auditory stimuli, the time course of event-related-potentials (ERP; N1 and P3b amplitudes) and the activity of cortical sources of the P3b component. Forty-eight participants completed an auditory oddball paradigm composed of standard, distractor, and target stimuli during a hypnosis (HYP), a simulation of hypnosis (SIM), a distraction (DIS), and a control (CON) condition.
