New advances in science and technology are increasingly unveiling the functioning procesess of our brain. Aiming to encourage your critical thinking, here is a recent article published in The Guardian on 29/04/2012 presenting two different views on the importance of the subconscious.
To illustrate the relevance of hypnosis and its potential therapeutic value, here is another article from the Guardian 2004. Scientists observed clear changes in the brain functioning under a hypnotic state and pointed out the value of this altered state of consciousness for the altering of perception of pain.
While we are not still certain of the specific functioning of the brain, clinical experiments and investigations show us the the hypnotic state does provoke a particular brain activation different from that of our normal state of awareness. This is what we are using in clinical hypnotherapy in order to promote your self control over your thoughts, emotions and behaviour.
