Gruzelier and his colleagues studied brain activity using an fMRI while subjects completed a standard cognitive exercise, called the Stroop task. The team screened subjects before the study and chose 12 that were highly susceptible to hypnosis and 12 with low susceptibility. They all completed the task in the fMRI under normal conditions and then again under hypnosis. Throughout the study, both groups were consistent in their task results, achieving similar scores regardless of their mental state. During their first task session, before hypnosis, there were no significant differences in brain activity between the groups. But under hypnosis, Gruzelier found that the highly susceptible subjects showed significantly more brain activity in the anterior cingulate gyrus than the weakly susceptible subjects. This area of the brain has been shown to respond to errors and evaluate emotional outcomes. The highly susceptible group also showed much greater brain activity on the left side of the prefrontal cortex than the weakly susceptible group. This is an area involved with higher level cognitive processing and behaviour.[178][179]
Preliminary research has expressed brief hypnosis interventions as possibly being a useful tool for managing painful HIV-DSP because of its history of usefulness in pain management, its long-term effectiveness of brief interventions, the ability to teach self-hypnosis to patients, the cost-effectiveness of the intervention, and the advantage of using such an intervention as opposed to the use of pharmaceutical drugs.[91]
In no way are the Hypnotherapy Academy’s services to be interpreted as providing medical or psychiatric services. Hypnotherapy services are not offered as a replacement for counseling, psychotherapy, psychiatric or medical treatment. Hypnotherapy is an educational process that facilitates access to internal resources that assist people in increasing motivation, or altering behavior patterns to create positive change. The education of hypnotherapy is classified under Human Services in the Health and Human Services Division of the Classification of Instructional Programs by the United States Department of Education.

In this state, you are also highly suggestible. That is, when the hypnotist tells you do something, you'll probably embrace the idea completely. This is what makes stage hypnotist shows so entertaining. Normally reserved, sensible adults are suddenly walking around the stage clucking like chickens or singing at the top of their lungs. Fear of embarrassment seems to fly out the window. The subject's sense of safety and morality remain entrenched throughout the experience, however. A hypnotist can't get you to do anything you don't want to do.

As with other treatment providers, recommendations from family or friends are a great place to start. You can also check with a therapist, naturopath, or acupuncturist for recommendations. There are several databases of certified hypnotherapists online too. Try checking the American Society of Clinical Hypnosis’s database, or the General Hypnotherapy Register. You’ll want to check the therapist’s website before you choose, making sure to look for credentials and testimony from previous patients if available.
Pierre Janet originally developed the idea of dissociation of consciousness from his work with hysterical patients. He believed that hypnosis was an example of dissociation, whereby areas of an individual's behavioural control separate from ordinary awareness. Hypnosis would remove some control from the conscious mind, and the individual would respond with autonomic, reflexive behaviour. Weitzenhoffer describes hypnosis via this theory as "dissociation of awareness from the majority of sensory and even strictly neural events taking place."[38]
Trance is commonplace. People fall into traces many times without even being aware that it happened. Examples of this are: reaching the destination of a morning commute, but not recalling the passing of familiar landmarks; daydreaming while sitting in a college classroom; or that anxiety-free state achieved just before going to sleep. The difference between these altered states and clinically used hypnotherapy is that a professionally trained person is involved in helping the patient achieve the trance, which can be done in many ways.
Confusion can occur when one seeks a hypnotherapist, as a result of the various titles, certifications, and licenses in the field. Many states do not regulate the title "hypnotist" or "hypnotherapist," so care must be exercised when selecting someone to see. As a rule, it is best to consult a professional in the field of mental health or medicine, although alternative sources for hypnosis are available. Care must be taken also by the therapist to ensure adequate training and sufficient experience for rendering this specialized service. The therapist must be well grounded in a psychotherapeutic approach before undertaking the use of hypnotherapy. Professionals should not attempt hypnotherapy with any disorder for which they would not use traditional therapeutic approaches. The patient seeking hypnotherapy is reminded that unskilled or amateur hypnotists can cause harm and should not be consulted for the purpose of implementing positive change in an individual's life. The detrimental effects of being subjected to amateur or inadequately trained persons can be severe and long lasting. (See abnormal results below.)
Stage hypnosis is a form of entertainment, traditionally employed in a club or theatre before an audience. Due to stage hypnotists' showmanship, many people believe that hypnosis is a form of mind control. Stage hypnotists typically attempt to hypnotise the entire audience and then select individuals who are "under" to come up on stage and perform embarrassing acts, while the audience watches. However, the effects of stage hypnosis are probably due to a combination of psychological factors, participant selection, suggestibility, physical manipulation, stagecraft, and trickery.[152] The desire to be the centre of attention, having an excuse to violate their own fear suppressors, and the pressure to please are thought to convince subjects to "play along".[153] Books by stage hypnotists sometimes explicitly describe the use of deception in their acts; for example, Ormond McGill's New Encyclopedia of Stage Hypnosis describes an entire "fake hypnosis" act that depends upon the use of private whispers throughout.
In as much as patients can throw themselves into the nervous sleep, and manifest all the usual phenomena of Mesmerism, through their own unaided efforts, as I have so repeatedly proved by causing them to maintain a steady fixed gaze at any point, concentrating their whole mental energies on the idea of the object looked at; or that the same may arise by the patient looking at the point of his own finger, or as the Magi of Persia and Yogi of India have practised for the last 2,400 years, for religious purposes, throwing themselves into their ecstatic trances by each maintaining a steady fixed gaze at the tip of his own nose; it is obvious that there is no need for an exoteric influence to produce the phenomena of Mesmerism. […] The great object in all these processes is to induce a habit of abstraction or concentration of attention, in which the subject is entirely absorbed with one idea, or train of ideas, whilst he is unconscious of, or indifferently conscious to, every other object, purpose, or action.[52]

Sessions with a Professional Hypnotherapist can relieve stress, insomnia and physical discomfort, change negative or limiting habits and beliefs, improve self esteem, confidence, motivation, creativity, learning, and memory. And there are many other challenges people face in their lives that can be changed or eliminated with hypnosis, including the 2 more well known reasons people contact a hypnotist, stop smoking hypnosis and hypnosis weight loss.
In 1974, Theodore X. Barber and his colleagues published a review of the research which argued, following the earlier social psychology of Theodore R. Sarbin, that hypnotism was better understood not as a "special state" but as the result of normal psychological variables, such as active imagination, expectation, appropriate attitudes, and motivation.[16] Barber introduced the term "cognitive-behavioral" to describe the nonstate theory of hypnotism, and discussed its application to behavior therapy.
