Following the French committee's findings, Dugald Stewart, an influential academic philosopher of the "Scottish School of Common Sense", encouraged physicians in his Elements of the Philosophy of the Human Mind (1818)[54] to salvage elements of Mesmerism by replacing the supernatural theory of "animal magnetism" with a new interpretation based upon "common sense" laws of physiology and psychology. Braid quotes the following passage from Stewart:[55]
A hypnotherapist can work with you to find the technique that can work best for what you're trying to accomplish. Although it's important to begin by working with a hypnotherapist, the hypnotherapist can then teach you self-hypnosis so you can practice at home. Once you have a firm grip on an issue like pain or fatigue with the therapist, you can continue on your own with self-hypnosis.
But for the comparison between PHA and functional amnesia to be most meaningful, we need to know that they share underlying processes. One way to test this is to identify the brain activity patterns associated with PHA. In a groundbreaking study published in Neuron, neuroscientist Avi Mendelsohn and colleagues at the Weizmann Institute in Israel did just that using functional magnetic resonance imaging (fMRI). They carefully selected 25 people to participate in their experiment. Although all were susceptible to hypnosis, earlier testing had shown that half could respond to a PHA suggestion (labelled “the PHA group”) and half could not (the “non-PHA group”). In the Study session of their experiment, participants watched a 45-minute movie. One week later, in the Test session, participants returned to the laboratory and were hypnotized while they lay within the fMRI scanner. During hypnosis, people in both the PHA and non-PHA groups received a suggestion to forget the movie until they heard a specific cancellation cue.
Despite briefly toying with the name "rational Mesmerism", Braid ultimately chose to emphasise the unique aspects of his approach, carrying out informal experiments throughout his career in order to refute practices that invoked supernatural forces and demonstrating instead the role of ordinary physiological and psychological processes such as suggestion and focused attention in producing the observed effects.
But how does the suppression mechanism decide what to suppress? In this study, movie content but not movie context was influenced by PHA. Memories involve the “what,” “how,” “when” and “where” of an event interwoven together, such that distinctions between content and context may be blurred (for example, “Was the movie shot with a hand-held camera?”). To make such fine discriminations, the brain’s suppressor module presumably needs to process information at a sufficiently high level. Yet this module needs to act quickly, preconsciously suppressing activation of the information before it even enters awareness. Brain imaging technologies with superior temporal resolution to fMRI, such as magnetoencephalography (MEG), might help to resolve this seeming paradox of sophisticated, yet rapid, operations.
Hypnosis for weight loss or to quit addictive behaviors like smoking or drinking, is how most people think of hypnosis. While people do often seek hypnosis therapy for these reasons, there are other reasons too. People may see a hypnotherapist before and during childbirth or to increase self-esteem. It can also be used to deal with chronic pain, insomnia, anxiety, or treat irritable bowel syndrome.
     "This is to thank you for allowing me to take the 4 full Level classes again and be a diligent analyst of your unparalleled methods. Taking the full course again has been most insightful and rewarding on both professional and personal levels. Although the program foundation is similar, the cases and studies in class have been rewardingly new and inspiring to me.
During hypnosis, a person is said to have heightened focus and concentration. The person can concentrate intensely on a specific thought or memory, while blocking out sources of distraction.[7] Hypnotised subjects are said to show an increased response to suggestions.[8] Hypnosis is usually induced by a procedure known as a hypnotic induction involving a series of preliminary instructions and suggestion. The use of hypnotism for therapeutic purposes is referred to as "hypnotherapy", while its use as a form of entertainment for an audience is known as "stage hypnosis". Stage hypnosis is often performed by mentalists practicing the art form of mentalism.
A typical hypnotherapy session has the patient seated comfortably with their feet on the floor and palms on their lap. Of course, the patient could choose to lie down if that option is available and if that will meet the patient's expectation of hypnosis. The therapist can even set the stage for a favorable outcome by asking questions like, "Would you prefer to undergo hypnosis in this chair or on the sofa?" Once patients make the choice, they are in effect agreeing to undergo hypnosis. Depending on the approach used by the therapist, the next events can vary, but generally will involve some form of relaxing the patient. Suggestions will lead the patient to an increasingly relaxed state. The therapist may wish to confirm the depth of trance by performing tests with the patient. For example, the therapist may suggest that when the eyes close that they will become locked and cannot be opened. The therapist then checks for this by having patients try to open their eyes. Following a successful trial showing the patient's inability to open the eyes, the therapist might then further relax them by using deepening techniques. Deepening techniques will vary for each patient and depend largely on whether the patient represents information through auditory, visual, or kinesthetic means. If the patient is more affected by auditory suggestions, the therapist would use comments such as "You hear the gentle patter of rain on the roof;" or, "The sound of the ocean waves allow you to relax more and more." For the visual person, the therapist might use statements such as, "You see the beautiful placid lake, with trees bending slightly with the breeze." Finally, with the kinesthetic person phrases such as, "You feel the warm sun and gentle breeze on your skin," could be used. It is important for the therapist to know if the patient has difficulty with the idea of floating or descending because these are sometimes used to enhance the experience for the patient. However, if the patient has a fear of heights or develops a feeling of oppression with the thought of traveling downward and going deeper and deeper, suggestions implying the unwanted or feared phenomenon will not be taken and can thwart the attempt.
Evidence from randomized controlled trials indicates that hypnosis, relaxation, and meditation techniques can reduce anxiety, particularly that related to stressful situations, such as receiving chemotherapy (see box). They are also effective for insomnia, particularly when the techniques are integrated into a package of cognitive therapy (including, for example, sleep hygiene). A systematic review showed that hypnosis enhances the effects of cognitive behavioral therapy for conditions such as phobia, obesity, and anxiety.

The earliest definition of hypnosis was given by Braid[contradictory], who coined the term "hypnotism" as an abbreviation for "neuro-hypnotism", or nervous sleep, which he contrasted with normal sleep, and defined as: "a peculiar condition of the nervous system, induced by a fixed and abstracted attention of the mental and visual eye, on one object, not of an exciting nature."[21]
Many of the clucking chicken images are the result of hypnosis’s forefather, Franz Anton Mesmer (1734-1815). Mesmer believed that there was an invisible force, a cosmic energy, that could be harnessed by one person to influence another person’s behavior. While his theory was wrong, the techniques he used were effective. These techniques were picked up on and developed over the coming years for therapeutic and medical purposes. Sigmund Freud, for instance, used hypnosis techniques. In the mid-1900s, hypnotherapy as we know it evolved. Milton Erickson (1901-1980) pioneered “indirect hypnosis,” during which therapists work with individual patients to shift their perceptions of themselves and their issues.
In the 1950s, Milton H. Erickson developed a radically different approach to hypnotism, which has subsequently become known as "Ericksonian hypnotherapy" or "Neo-Ericksonian hypnotherapy." Erickson made use of an informal conversational approach with many clients and complex language patterns, and therapeutic strategies. This divergence from tradition led some of his colleagues, including Andre Weitzenhoffer, to dispute whether Erickson was right to label his approach "hypnosis" at all.[10]
