Brain functional connectivity of hypnosis without target suggestion. An intrinsic hypnosis rs-fMRI study.

Objective: During hypnosis, significant changes in the BOLD signal associated with the anterior default mode network (DMN) and prefrontal attentional systems have been reported as evidence of defined since Charcot. However, it remains uncertain whether these changes are mainly attributable to the hypnotic state or to the target suggestions used to verify subject's state during neuroimaging studies. The aim of the present study is to evidence the brain in hypnosis, contrasting the common resting state versus (hypnosis in the absence of target suggestions).
