Brain Activity and Functional Connectivity Associated with Hypnosis
Open accessAbstract
Hypnosis has proven clinical utility, yet changes in brain activity underlying the hypnotic state have not yet been fully identified. Previous research suggests that hypnosis is associated with decreased default mode network (DMN) activity and that high hypnotizability is associated with greater functional connectivity between the executive control network (ECN) and the salience network (SN). We used functional magnetic resonance imaging to investigate activity and functional connectivity among these three networks in hypnosis. We selected 57 of 545 healthy subjects with very high or low hypnotizability using two hypnotizability scales. All subjects underwent four conditions in the scanner: rest, memory retrieval, and two different hypnosis experiences guided by standard pre-recorded instructions in counterbalanced order. Seeds for the ECN, SN, and DMN were left and right dorsolateral prefrontal cortex, dorsal anterior cingulate cortex (dACC), and posterior cingulate cortex (PCC), respectively. During hypnosis there was reduced activity in the dACC, increased functional connectivity between the dorsolateral prefrontal cortex (DLPFC;ECN) and the insula in the SN, and reduced connectivity between the ECN (DLPFC) and the DMN (PCC). These changes in neural activity underlie the focused attention, enhanced somatic and emotional control, and lack of self-consciousness that characterizes hypnosis.

TL;DR
This fMRI study compared highly hypnotizable and minimally hypnotizable healthy adults during hypnosis and control conditions, focusing on executive control, salience, and default mode networks. Hypnosis in highs was linked to lower dACC activity, stronger DLPFC-insula coupling, and weaker DLPFC-default mode connectivity, with effects tracking reported hypnotic depth.
Key findings
- Among high hypnotizables, hypnosis reduced dACC fALFF relative to rest; the group-by-condition interaction was significant, and greater reported hypnotic intensity correlated with lower dACC fALFF (figure reports r = -0.72; TFCE P < 0.001 uncorrected). dACC activity decreased in a graded way across hypnosis, memory, and rest for highs, while lows showed the reverse pattern.
- Highs showed increased functional connectivity between left DLPFC and ipsilateral insula plus contralateral supramarginal gyrus during hypnosis vs rest compared with lows (P < 0.05, GRF corrected). Within highs, left DLPFC-insula and right DLPFC-bilateral insula connectivity increased during hypnosis vs rest; insula, middle frontal, and superior parietal clusters correlated positively with hypnosis ratings.
- As hypnosis intensity increased among all 36 highs, connectivity between bilateral DLPFC and default mode regions (PCC, contralateral IPL, mPFC) decreased during hypnosis; this decoupling was not seen during rest or memory. Connectivity within the DMN itself was not altered by hypnosis.
- Lows showed no significant hypnosis-vs-rest connectivity differences for either DLPFC seed.
Methods
- 545 healthy participants were screened with HGSHS:A and HIP; 36 highs and 21 lows were scanned. Between-group fMRI analyses used 21 highs with the highest hypnosis ratings matched to 21 lows; covariate analyses used all 36 highs.
- Four counterbalanced 8-min fMRI conditions were used: rest, autobiographical memory, hypnotic happiness, and hypnotic vacation, with standardized pre-recorded instructions/inductions. Scanning was on a 3T GE scanner with 31 axial slices, TR = 2000 ms, TE = 30 ms.
- Analyses included fALFF for regional spontaneous activity and seed-based functional connectivity with left/right DLPFC, dACC, and PCC seeds, using FSL, TFCE, and GRF cluster correction; physiological and movement covariates were checked.
Limitations
- The paper notes that some secondary findings were uncorrected for multiple comparisons, including the dACC fALFF correlation with hypnotic intensity and the group interaction at P < 0.001; the right DLPFC-insula interaction did not survive correction, and PCC/dACC seed group-by-condition comparisons did not survive correction.
- The paper reports that the memory control condition unexpectedly produced network changes resembling hypnosis, so it may not have served as a clean control; the authors suggest any focused task in highs might induce similar changes.
- Evident from the text: between-group analyses relied on 21 highs and 21 lows, with all 36 highs used only for within-group covariate analyses; participants were healthy volunteers selected at the extremes of hypnotizability, so generalizability is limited. The paper does not present a formal limitations section.

The ‘Functional connectivity of the human insula and the salience network’ section identifies the anterior insula and dorsal ACC as salience-network components. ‘Multiple functions of the insula’ links insular function to visceral and somatic processes, and ‘Saliency, attention, and cognitive control’ distinguishes the anterior insula’s transient salience detection from ACC functions.

The Discussion (‘Brain activity associated with self-reflection’; page not supplied) identifies insular activity during self-reflection. The paper does not establish that the insular cortex is involved in self-monitoring or self-regulation; its discussion of monitoring and a regulatory network concerns the anterior cingulate cortex.

“the insula is involved in the processing of body control and experience, emotion, empathy, and time through its extensive connections to cortical and subcortical limbic structures (Menon and Uddin 2010;Cai et al. 2014).”
§ Brain Activity and Functional Connectivity Associated with Hypnosis > Discussion
What the sources say
- Partly supportedcites Menon and Uddin 2010 sourceExperimental — accuracy not yet measured
The sections “Multiple functions of the insula: toward a network model” and “Structural connectivity of the insula” describe roles in bodily-state awareness, autonomic control, emotion, and empathy, alongside connections with other brain regions (page numbers unavailable). Our copy does not establish a role in processing time, nor does it attribute all the listed functions specifically to extensive cortical and subcortical limbic connections. (LLM, conf=0.87)
- Partly supportedcites Cai et al. 2014 sourceExperimental — accuracy not yet measured
The meta-analysis section says that anterior-ventral and posterior insular subdivisions have been implicated in affective and interoceptive processes, which partly supports the references to emotion and bodily experience. The intrinsic functional connectivity section reports connections between the right anterior insula and several cortical and subcortical regions. Neither passage supports empathy or time processing, nor establishes that the listed functions arise through connections to limbic structures. (LLM, conf=0.84)

Self-reported intensity of hypnotic experience is a valid measure of the depth of hypnosis.
“All subjects were asked to rate on a scale of 1-10 how hypnotized they felt during each of the two hypnotic scans, with one indicating”
“As a manipulation check, at the end of each condition subjects rated how hypnotized (or drowsy, in the rest and autobiographical memory scans) they felt on a scale of 1-4 using a button box.”
The paper relies on this without support.
The two hypnosis conditions, hypnotic happiness and hypnotic vacation, both induce a common hypnotic state that can be averaged to index hypnosis.
“We chose to structure the content of the two hypnosis conditions rather than simply provide an hypnotic induction with no further guidance.”
“beta values for the two hypnosis conditions were averaged after regression for each subject”
The paper relies on this without support.
Post-scan intensity of hypnosis ratings validly measure the subjective intensity of hypnosis.
“Hypnotic response scores correlate with fALFF: blue regions show decreasing fractional amplitude during hypnosis relative to rest as post-scan intensity of hypnosis ratings increases, among all 36 highs.”
“Connectivity during the two hypnotic states (averaged across happy/vacation) covaried with mean intensity of hypnosis ratings for 36 highs: regions in blue exhibit decreased FC with left (A) and right (B) DLPFC among subjects who felt more hypnotized.”

Statistics that don’t add up
Each reported p-value recomputed from its test statistic and degrees of freedom.
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-15, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-15 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
