Shared neural mechanisms of trait mindfulness and hypnotic susceptibility: A scoping review toward a unifying...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychophysiology

Background:

• Compares neural mechanisms of trait mindfulness and hypnosis susceptibility.
• Focuses on brain region activation, electroencephalographic (EEG) signals, and brain networks.
• Aims to identify shared mechanisms in conscious state modulation.

Purpose of the Study:

• To systematically compare the neural underpinnings of trait mindfulness and hypnosis susceptibility.
• To elucidate shared neural mechanisms involved in modulating conscious states.
• To propose an integrative framework based on predictive coding theory.

Main Methods:

• Scoping review of brain imaging and electroencephalographic (EEG) studies.
• Systematic comparison of findings related to brain regions, EEG rhythms, and network dynamics.
• Application of predictive coding theory for interoception.

Main Results:

• Shared involvement of prefrontal cortex and anterior cingulate cortex.
• Enhanced theta and alpha EEG rhythms observed in both conditions.
• Dynamic interaction between salience and central executive networks is crucial.
• Trait mindfulness enhances perceptual inference and metacognitive awareness.
• Hypnosis susceptibility facilitates acceptance of prior cues and promotes active inference.

Conclusions:

• Proposes an integrative framework for trait mindfulness and hypnosis susceptibility.
• Highlights their joint influence on cognitive processes and self-conscious states.
• Identifies potential for future research and clinical applications, such as anxiety interventions.
