Knowledge of where the unconsciousness has its fysical position in the brain, we have from the brainresearch. The consciosness has connexion with the sympathetic nervous system, which is regulated by centres in the big brain(cerebrum). This system controls among others the muscle sections we control ourselves, such as raise the leg, nod the head., point the finger and so on. Our thinking forexample takes place in the cerebrum. The unconsciousness is to a higher extent attached to the autonomous nervous system, of which controls the muscle sections we cannot control ourselves, and taking care of the heart function, breath, digestion and so on . The autonomous system is also called the vegetative nervous system , because we have restricted chance of exercising conscious control of it. However by means of hypnosis it is fully possible to influence the autonomous system, and forexample overcome blushing, strain, tremor and the like.

We can locate the unconsciousness first and foremost to the limbic system, between cerebrum and the middle brain. Particularly two nerve centres in the limbic system – hypothalamus and amygdala - are important. They are both profoundly located in the brain, and since they form the centre of the autononous nervous system, they strongly contribute to influence our feelings as well as the unconsciousness. Of which hypothalamus watches body temperature, blood sugar, appetite, sexual desire and menstruation. The small brain (cerebellum) operates on subconscious level by regulating the gestures controlled by the musculature we can command, and by bringing the body in balance.

Hypnosis is a context for psychotherapy, and not a therapy system in itself. In hypnosis we induce responsivity, collect ressources, and use it for problem areas. By use of hypnosis we can intervene directly as well as indirectly, consciously as well as unconsciously.
For example facing persons with an ambivalent attitude to performance, it can be necessary to reformulate the problems by attaching importance to other aspects of the persons acting than evaluating the achievements. Hypnosis implies in no way that one by-passes psychological legalities or typical individual responses. On the contrary they will be generated faster, and one is obliged to record, prepare and utilize them in order to increase the effectivity of the therapy. For instance a concrete specification of how one imagines that endorphines are formed fysiological and biochemical, can help the client to create a pleasant, effective and useful visual picture of the process. This can contribute to pain reduction. Also changing the “inner dialogue” can successfully be useful within hypnosis treatment. Reseach proves that the intensity and the reality feature of the imagination increases during hypnosis.

The great advantage of hypnosis is the concentration and possibility of demarcation of psychological variables. During ordinary awaken interaction far to many chances arise for diversion. One must make up one`s mind about too many experiences at the same time. The quiet of the hypnosis, the relaxation and concentration makes the intervention more effective because one by-passes needless diversion.

In spite of distinct definitions of the phenomenon hypnosis, it is in any case possible to describe what most people experience in a hypnotic state. The maybe most important thing is a feeling of comfort, tranquillity and relaxation . Strange to say - in proportion to popular mistakes of what hypnosis is – the hypnotic state allows a feeling control. Hypnosis is first and foremost a state where one experiences that one can choose between mental, emotional and behavioral adventures of phenomenons ordinarily not admitted. Most people experience that the body becomes heavy. The feeling of gravity in connection with relaxation
and slackening is in most cases immensely pleasant. Some people experience a feeling of relief in the body, a floating or flowing impression positive and agreeable as well. In addition during hypnosis one can also have access to memories and imagination, one is usually not in touch with. For example in relation to memories from the childhood, that one can relive in a distinct intense and concrete manner. Another common phenomenon is that the perception of time is altered in the hypnotic state. Generally, after the hypnosis, a person will believe that the time he has been in trance, is much shorter than the time that actually passed. A person can find himself in a trance for a half or a whole hour, but undergoes the impression that it all went on for five or ten minuttes.

Research has demonstrated obvious distinctions between sleep and hypnosis. The most evident difference is that in hypnosis one is able to be sensitive and respond to verbal stimuli from the therapist. In many cases it happens that someone can fall into a sleeplike state in hypnosis without any spesific suggestions about it. Clinical experience point in the direction that hypnosis and sleep are qualitative two different conditions. Hypnosis gives a unique chance of conscious choice and concentration, contrary to the “passive sleep”. That implies, however, that hypnosis can also just be used to bring about sleep, and be a usefull remedy in the treatment of insomnia. Hypnosis is not a passive, but an active state. Dissociation in this sense implies a repression of conscious actions, so that gradually more stimuli are divided from the consciousness. A person in deep hypnotic state can allow the voice of the therapist to be the only source of stimuli.

Frequently one must spend time to inform and prepare different misunderstandings with the client before hypnosis can be applied for therapeutic purpose. The client must become acquainted with the trance experiences. Some believe that the hypnotic state is dangerous. Some believe it leads to altering of our nervous system. No research has proved that fundamental fysiological situations alters as a result of beeing hypnotized. The responsible therapist must pay attention to such opinions by the relief seeker. Because information about the relational importance and the understanding of the interaction between the therapist and the client is so vital to understand the hypnotic phenomenon, proffesional authority must be emphasized.

Hypnosis is not a treatment method, but a special kind of communication. These qualifications must be applied in the work and by redefining seemingly mistakes and defeats.
This is one of the reasons that we in Norway have a strict legal statutory of who is permitted to utilize hypnosis in research and clinical context. Only psychologist and doctors are allowed to practise hypnosis in Norway. Application of hypnosis is a very powerfull agent, but should only be interpreted as one method among others that can be utilized within the context of integrated psychotherapy.
