Hypnotic Trance Changes Brain Patterns and Activity

 

 

Hypnosis is a change of state, there must also be some type of change in the brain and brain patterns. And there must be a way of seeing this change too.

In 2016, Spiegel and a team of researchers decided to prove their suspicions.

Spiegel’s Study: Brain Activity And Functional Connectivity Associated With Hypnosis

The purpose of the study was to try to identify changes in brain activity during the hypnotic state.

According to the study’s abstract, the team knew that hypnosis was associated with “decreased default mode network (DMN) activity,” and that people who were highly hypnotizable showed “greater functional connectivity between the executive control network (ECN) and the salience network (SN).”

From a group of 547 people, Spiegel and his colleagues chose 57 subjects – 36 with high hypnotizability and 21 with low hypnotizability.

Both groups were subjected to a series of fMRI (functional magnetic resonance imaging) scans under the same 4 conditions:

  • while resting
  • when recalling a memory; and
  • during two different hypnosis experiences guided by pre-recorded instructions
