Hypnotizability-related integration of perception and action

A highly pervasive role of hypnotic susceptibility in human behaviour through the modulation of the integration of perception and action is suggested, which could be relevant for neurorehabilitative treatments and for the adaptation to special environments.

Frontal functions, connectivity and neural efficiency underpinning hypnosis and hypnotic susceptibility

This study disclosed the importance of neural efficiency in left lateral frontal and anterior cingulate structures, and their connectivity, for distinguishing high from low hypnotic susceptibility both in hypnosis and in the everyday state.

Hypnotic Ability and Baseline Attention: fMRI Findings From Stroop Interference

Findings from functional magnetic resonance imaging (fMRI) show that high-hypnotizable participants, compared with low- Hypnotizables, may maintain a distinct baseline of attention even outside of hypnosis or suggestion.

Neurocognition Under Hypnosis: Findings From Recent Functional Neuroimaging Studies

Functional neuroimaging studies show that hypnosis affects attention by modulating anterior cingulate cortex activation and uncoupling conflict monitoring and cognitive control function, and that posthypnotic suggestions alter cognitive processes.

Hypnotizability and spatial attentional functions.

The findings suggest that Highs would be endowed with a basal higher efficiency in achieving and maintaining their readiness to respond to incoming stimuli, in terms of a possible more efficient noradrenergic activity driven by frontal attentional systems.

Neural functional correlates of hypnosis and hypnoanalgesia: Role of the cingulate cortex

The study of the functionality of the cingulate cortices, mainly the anterior and medial portions, appears to be crucial for better understanding the hypnotic phenomena, related to both the neurocognitive and somatosensory aspects.

Findings indicate that although the frontal area may play an important role regarding hypnotic response, the mechanisms seem to be much more complex than mere general inhibition.

Cerebral Mechanisms of Hypnotic Induction and Suggestion

Results support a state theory of hypnosis in which occipital increases in rCBF and delta activity reflect the alteration of consciousness associated with decreased arousal and possible facilitation of visual imagery.

Hypnosis Modulates Activity in Brain Structures Involved in the Regulation of Consciousness

Regression analyses between regional cerebral blood flow (rCBF) and self-ratings confirm the hypothesized involvement of the anterior cingulate cortex, the thalamus, and the ponto-mesencephalic brainstem in the production of hypnotic states.

The neural correlates and functional integration of cognitive control in a Stroop task

Increased anterior corpus callosum size associated positively with hypnotizability and the ability to control pain.

Results provide support to the neuropsychophysiological model that HHs have more effective frontal attentional systems implementing control, monitoring performance and inhibiting unwanted stimuli from conscious awareness, than LHs.
