fMRI shows hypnosis produces measurable changes in brain connectivity that are distinct from both resting state and sleep — here is what the evidence actually demonstrates.
Key Takeaway
Hypnosis produces measurable, reproducible changes in brain functional connectivity that differ from both ordinary waking consciousness and other altered states. These changes are not artefacts of relaxation or suggestion — they reflect a distinct neurophysiological state that varies with hypnotic susceptibility [1, 2].
The Research Question
For decades, clinicians and researchers debated whether the hypnotic trance represents a distinct neurophysiological state or is merely a product of expectation, social compliance, and focused attention. Early neuroimaging studies produced mixed results, partly because they often combined trance induction with specific suggestions [3].
Intrinsic Hypnosis: Separating State from Suggestion
A landmark 2024 study by Vázquez and colleagues addressed this confound directly using an “intrinsic hypnosis” resting-state fMRI paradigm [1]. They found increased functional connectivity within parieto-occipital regions and decreased connectivity between frontal executive networks and the default mode network (DMN) [1].
Hypnotic Susceptibility and Brain Structure
Hoeft and colleagues (2012) demonstrated that highly hypnotisable individuals show greater resting-state connectivity between the dlPFC and DMN [2]. Jiang and colleagues (2017) confirmed the salience network moderates the hypnotic response [3].
Clinical Implications
Miltner and colleagues’ 2024 review confirmed hypnotic analgesia attenuates pain-related cortical activation [4]. Clinicians can now point to reproducible fMRI data when clients ask whether trance is “real.”

For years, hypnotherapy and CBT have been framed as competitors. But a growing body of research suggests the real story is more nuanced — and more collaborative.
The Landscape: Two Approaches, One Goal
Cognitive Behavioural Therapy (CBT) and hypnotherapy are two of the most empirically supported psychological interventions available. CBT focuses on restructuring conscious thoughts and behaviours through structured, often manualised protocols, while hypnotherapy leverages trance states to access unconscious resources and reframe deeply held patterns [1]. Both aim to reduce distress and improve functioning, but they operate through fundamentally different mechanisms — raising the question of whether they compete or complement each other.
What the Comparative Research Shows
A recent randomised controlled trial directly comparing Ericksonian Hypnotherapy and CBT for subclinical depression and anxiety found that both approaches produced significant symptom reduction, with no statistically significant difference between them at post-treatment or follow-up [1]. This suggests that both modalities are effective, but through potentially different pathways — CBT through cognitive restructuring, hypnotherapy through accessing implicit memory networks and unconscious resources [2]. The study also noted that hypnotherapy showed slightly faster initial response rates, though the difference did not reach significance.
The Case for Cognitive Hypnotherapy
Rather than treating CBT and hypnotherapy as competitors, an emerging integrative model — cognitive hypnotherapy — combines the structured cognitive interventions of CBT with the depth-oriented access provided by hypnotic techniques [2]. Clinical trials have shown that cognitive hypnotherapy can be more effective than either modality alone for specific conditions, particularly anxiety disorders [2]. The hypnotic component facilitates access to emotional memories and automatic thoughts more rapidly than talk-based CBT alone, potentially accelerating therapeutic progress.
When Each Approach Shines
CBT may be the preferred first-line approach for clients who are highly rational, prefer structured homework, or whose primary challenges involve clearly identifiable cognitive distortions. Hypnotherapy may be particularly effective for clients with strong somatic components to their distress, those who have not responded to purely cognitive approaches, or clients who are already comfortable with metaphor and imagery [1]. In practice, many clinicians find that the two approaches inform each other — CBT provides the structure, hypnotherapy provides the access.
The Verdict: Collaboration Over Competition
The current evidence base supports a collaborative rather than competitive framing. Professional bodies in the UK and Australia increasingly recognise both modalities as evidence-based, and training programmes that integrate CBT principles with hypnotherapeutic techniques are growing [1]. For students deciding which to study, the most pragmatic answer may be: learn both. The most effective practitioners are those who can draw on multiple evidence-based frameworks and match their approach to the individual client.
