Stanford Medicine Study Identifies Brain Areas Altered During Hypnotic Trances

For years, hypnosis has been surrounded by myths and misconceptions. Some people believe it's simply relaxation. Others think it's some form of mind control. Many assume it's just imagination. Researchers at Stanford Medicine decided to move beyond the debate and look at what was actually happening inside the brain during hypnosis. What they found was fascinating.

The study, published in the journal Cerebral Cortex, examined the brains of highly hypnotizable individuals while they were in a hypnotic trance. The researchers discovered measurable changes in several areas of the brain, suggesting that hypnosis is associated with a unique pattern of brain activity rather than simply being a state of relaxation or make-believe.

One of the most interesting findings was a decrease in activity in an area of the brain associated with distraction and mental chatter. In simple terms, the constant stream of thoughts, worries, and background noise that often fills our minds appeared to quiet down. This may help explain why many people describe hypnosis as a state of deep focus and concentration. Instead of attention constantly jumping from one thought to another, the mind seems able to settle and stay focused on a particular idea or experience.

The researchers also found stronger communication between areas of the brain involved in focused attention and body awareness. This finding may help explain why hypnosis can have such a powerful impact on how people experience stress, discomfort, habits, emotions, and even physical sensations. Most of us have experienced the connection between the mind and body. Stress can tighten our muscles. Anxiety can create butterflies in our stomach. Embarrassment can make us blush. During hypnosis, this connection appears to become even more pronounced.

Another significant discovery involved a reduction in communication between brain regions associated with self-reflection and self-judgment. This doesn't mean people stop thinking during hypnosis. Instead, it may mean they become less preoccupied with analyzing every thought, questioning every experience, or criticizing themselves. Anyone who has ever tried to make a meaningful change knows how often the mind gets in its own way. We overthink, second-guess ourselves, replay old stories, and worry about what might happen next. Hypnosis may temporarily quiet some of that internal commentary, allowing people to become more engaged in the process of change.

To me, this is where the study becomes especially meaningful. Most people already know what they want to change. They want to reduce stress, sleep better, feel more confident, improve performance, or break habits that no longer serve them. The challenge is rarely a lack of information. More often, it's the mental noise that keeps people stuck. Distraction, doubt, fear, and overthinking can all interfere with progress.

The Stanford study suggests that hypnosis may help create a mental state where some of those barriers begin to soften. When the mind becomes less distracted, more focused, and less consumed by self-judgment, positive change may become easier. That doesn't mean hypnosis is magic, and it certainly doesn't mean people lose control. In fact, the research suggests quite the opposite. People remain aware and engaged, but their attention becomes organized in a way that may support learning, healing, and personal growth.

Perhaps the most important takeaway from this research is that hypnosis isn't about giving up control of the mind. It may actually be about gaining greater control over where attention is directed. And sometimes, when attention shifts, everything else can begin to shift as well.
