Functional Neuroimaging Studies of Hypnosis and Meditation: A Comparative Perspective
Bibliographic record
Abstract
Over the last few decades, an increasing number of functional neuroimaging studies have been performed with respect to hypnosis and meditation. The objective of this article is to review a number of these studies to compare the neural substrates related to different components of hypnosis and meditation. We examine neuroimaging studies conducted to explore the impact of hypnosis on the brain regions and systems involved in color perception, hand paralysis, pain, and the default-mode network (DMN). We also review neuroimaging investigations carried out to examine the neural correlates of various meditation techniques, as well as the effects of meditation on the brain mechanisms related to emotion, pain, and the DMN. Given the discrepancy existing between the findings from neuroimaging studies of hypnosis and meditation carried out in regard to pain and the DMN, we conclude that it is premature to claim that hypnosis and meditation are mediated by similar brain systems and neural mechanisms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
