Structural and functional correlates of XXXX and suggestibility.

@entity1 @entity62 @entity92
UNASSIGNED: This study explores whether self-reported depth of hypnosis and hypnotic suggestibility are associated with individual differences in neuroanatomy and/or levels of functional connectivity. Twenty-nine @entity1 varying in suggestibility were recruited and underwent structural, and after a hypnotic induction, functional magnetic resonance imaging at rest. We used voxel-based morphometry to assess the correlation of @entity62 ( @entity62 ) and white matter (WM) against the independent variables: depth of hypnosis, level of relaxation and hypnotic suggestibility. Functional networks identified with independent components analysis were regressed with the independent variables. @entity92 ratings were positively correlated with @entity62 volume in the frontal cortex and the anterior cingulate cortex (ACC). Hypnotic suggestibility was positively correlated with @entity62 volume in the left temporal-occipital cortex. Relaxation ratings did not correlate significantly with @entity62 volume and none of the independent variables correlated with regional WM volume measures. Self-reported deeper levels of hypnosis were associated with less connectivity within the anterior default mode network. Taken together, the results suggest that the greater @entity62 volume in the medial frontal cortex and ACC, and lower connectivity in the DMN during hypnosis facilitate experiences of greater @entity92 . The patterns of results suggest that @entity92 and hypnotic suggestibility should not be considered synonyms.
