Highlights
• The power of delta, theta, alpha, beta, and gamma bands was different between HD and LD groups before and after hypnosis.
• The HD and LD groups had different functional connectivity in delta, theta, alpha, and beta bands before and after hypnosis.
• Dissociation may not be sufficient to explain the hypnotizability of all individuals.
Plain Language Summary
Most electroencephalogram (EEG) studies in hypnosis have allocated people into two groups: High and low hypnotizability. People who are candidates for hypnosis are typically prone to dissociation. In this regard, they are often divided into two groups: High dissociative (HD) and low dissociative (LD). In this study, changes in absolute power and functional connectivity between HD and LD groups were compared after a hypnotic induction. The results showed that the power of delta, theta, alpha, beta, and gamma bands was different between the two groups before and after hypnosis. Regarding functional connectivity, the difference was significant between the two groups in delta, theta, alpha, and beta bands. Therefore, it can be said that although the LD and HD groups have equal hypnotizability, the episodic prospection tasks do not involve the same neural networks in the two groups.
