The Science of Suggestibility - How Hypnosis Affects the Brain

Hypnosis may seems like a mysterious process, but at its core, it’s a state of highly focused attention and increased suggestibility. Clinical Hypnotherapy harnesses this natural state, and utilises it alongside Strategic Psychotherapy to help people make positive changes, from overcoming phobias to managing chronic pain. But what exactly happens in the brain during hypnosis, and why are some people more responsive to hypnotic suggestions than others? Let's dive into the science of suggestibility and explore how hypnosis affects the brain.

But just before we do, it’s worth noting that research on hypnosis is not just a recent trend. The Stanford University School of Medicine has conducted a Laboratory of Hypnosis Research since the 1950’s, now led by Dr David Spiegel, and many esteemed scientists and researchers have explored the subject, producing robust, peer reviewed evidence of the efficacy of hypnosis as a clinical tool.

Understanding Suggestibility

Suggestibility is the degree to which a person is open to accepting and acting on suggestions. It’s a crucial part of hypnotherapy, as it allows individuals to engage deeply with the process and make meaningful changes. While all of us experience varying levels of suggestibility daily, hypnosis intentionally enhances this state to create therapeutic benefits.

During hypnosis, suggestibility increases because the brain enters a state of deep focus and reduced critical judgement. This isn’t about control or manipulation but rather about creating a receptive mental environment where positive suggestions can take root more easily. This enhanced state allows for significant therapeutic benefits, as the mind becomes more open to exploring and addressing underlying issues.

The Brain on Hypnosis

Modern neuroscience has given us a window into what’s happening in the brain during hypnosis. Studies using brain imaging techniques, like MRI and EEG, reveal that hypnosis alters activity in several key brain regions involved in focus, self-awareness, and perception.

One of the most important areas affected during hypnosis is the anterior cingulate cortex. This part of the brain helps regulate attention and processes conflicting thoughts or information. Under hypnosis, this region becomes more active, allowing individuals to focus intensely on specific suggestions or ideas presented by the hypnotherapist. This intense focus is what enables people to, for instance, perceive pain differently or to feel more calm and relaxed.

Another key area is the default mode network (DMN), a set of brain regions (dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus) that work together when the mind is at rest or in a self-reflective state. In hypnosis, the DMN is less active, meaning the mind becomes less engaged in self-criticism or excessive internal dialogue. This reduction in self-focus allows individuals to set aside doubts, fears, or ingrained mental barriers, making them more open to suggestions that align with their goals.

Additionally, the dorsolateral prefrontal cortex, responsible for planning and decision-making, interacts more closely with the regions involved in emotional processing, like the amygdala, during hypnosis. This stronger link means that under hypnosis, emotional responses can be guided by logical or positive suggestions, making it possible to reshape unhelpful emotional reactions or automatic responses.

Why Are Some People More Hypnotisable Than Others?

Suggestibility varies from person to person, and research shows that certain personality traits, such as openness to experience, are associated with higher hypnotisability. People who are naturally imaginative, emotionally aware, and open-minded are often more responsive to hypnosis. However, even if someone isn’t highly suggestible, most people still benefit from hypnotherapy through regular practice, as it enhances focus and increases receptivity over time.

Hypnosis as a Tool for Change

Hypnosis isn’t magic; it’s a structured therapeutic process backed by science. Through understanding how hypnosis affects the brain, clinical hypnotherapists can help clients leverage suggestibility to achieve their therapeutic goals. Whether it’s managing stress, breaking unwanted habits, or finding relief from pain, hypnosis taps into the brain’s ability to rewire itself by working directly with subconscious beliefs and responses.

In summary, the science of suggestibility shows us that hypnosis is a powerful tool for positive change. By shifting the brain into a focused and receptive state, hypnosis makes it possible to reach goals that may seem out of reach in ordinary waking life. Far from being about mind control, clinical hypnotherapy empowers individuals to harness the full potential of their own minds, with scientifically backed techniques that make lasting transformation possible.

Clinical Hypnotherapy vs Stage Hypnosis - Busting The Myths!

When most people think of hypnosis, they imagine dramatic scenes from TV, movies and stage performances: a mesmerist swinging a pocket watch, subjects clucking like chickens, people seemingly losing control of themselves, or being controlled to act out evil deeds. It makes for good entertainment, but stage hypnosis is a world apart from Clinical Hypnotherapy, which is a professional practice rooted in therapeutic science. Let’s dive into the key differences and bust some of the myths surrounding hypnosis.

Myth #1: Hypnosis is Mind Control

One of the biggest misconceptions about hypnosis, largely fuelled by stage performances, is that it involves mind control. In Clinical Hypnotherapy, nothing could be further from the truth. Hypnotherapy is a therapeutic technique that induces a natural, focused state of concentration to help people access their subconscious mind, where they can better explore and address personal issues. It’s essential to understand that even in a hypnotic state, the person remains in control. A hypnotherapist cannot make a client do anything against their will or moral code. Instead, the client remains aware and actively participates in the process, using their own insights and responses.

Stage hypnotists, on the other hand, rely on suggestibility and showmanship. Stage hypnosis participants are often pre-selected for their willingness to play along or demonstrate a high degree of suggestibility during the audience selection phase. Stage hypnotists are very skilled in choosing who they work with to ensure a show with maximum impact. Unlike clinical sessions, people in stage shows are generally ready to put on a performance for the audience, knowing it’s all in good fun. Despite the seemingly dramatic responses, stage hypnosis has little to do with the therapeutic application of hypnosis.

Myth #2: Hypnotherapy and Stage Hypnosis Are the Same Thing

Another common myth is that stage hypnosis and Clinical Hypnotherapy are the same or serve a similar purpose. Clinical Hypnotherapy is a valid and research-backed therapeutic practice used to address various issues, such as managing pain, reducing stress and anxiety, enhancing confidence, removing dependencies, and treating phobias. Practised by trained professionals, Clinical Hypnotherapy is safe, structured, and tailored to each individual’s needs. By accessing the subconscious mind, clients work on understanding the roots of their concerns and problems, developing effective strategies to change unhelpful behaviours or beliefs.

Stage hypnosis, meanwhile, is solely for entertainment. While it might seem that the hypnotist has a “magical” ability to make people act in bizarre ways, the reality is that stage hypnosis involves a mix of crowd psychology, suggestion, and participants’ willingness to be part of the spectacle. In a clinical setting, no hypnotherapist would ever approach hypnosis with this kind of sensationalism.

Myth #3: You Can Get “Stuck” in Hypnosis

Many people worry that they might get “stuck” in a hypnotic state, unable to wake up or return to normal consciousness. This idea is a myth. In Clinical Hypnotherapy, hypnosis is a natural state of focussed attention, similar to daydreaming or meditation. Even if a hypnotherapy session were to end abruptly, the client would naturally and safely return to full awareness within moments. The hypnotherapist acts as a guide, helping the client enter a state of relaxation and focus, but the client is always in control of their experience.

The Real Value of Clinical Hypnotherapy

While stage hypnosis can be fun and entertaining, Clinical Hypnotherapy has a powerful therapeutic purpose. It’s a tool that can empower people to address deep-seated issues, develop coping skills, and improve their quality of life. By debunking the myths and understanding the true nature of hypnotherapy, people can make informed choices about using it as a beneficial therapy.

Clinical Hypnotherapy and stage hypnosis might share the word “hypnosis,” but they couldn’t be more different in application and intention. Clinical Hypnotherapy is about healing, self-improvement, and real transformation, while stage hypnosis is simply an act designed to entertain. By separating the facts from the myths, we can better appreciate hypnotherapy as a legitimate, effective, and respectful therapeutic practice that exists at the intersection of neuroscience, psychology and wellness.
