Hypnosis is “a special psychological state with certain physiological attributes  resembling sleep only superficially and marked by a functioning of the individual at a level of awareness other than the ordinary conscious state. “One theory suggests that hypnosis is a mental state,while another theory links hypnosis to imaginative role-enactment. Persons under hypnosis are said to have heightened focus and concentration with the ability to concentrate intensely on a specific thought or memory, while blocking out sources of distraction. Hypnosis is usually induced by a procedure known as a hypnotic induction involving a series of preliminary instructions and suggestions. The hypnotic suggestions may be delivered by a hypnotist in the presence of the subject, or may be self-administered. 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 ”.

A. A Hypnosis Has been Shown through a number of Rigorously controlled studies to reduce pain, control blood pressure, and even make warts go away. But because very few studies have attempted to define the actual processes involved, most scientists are sceptical of its power and uses. That scepticism has driven David Spiegel, a professor of Psychiatry at Stanford University School of Medicine, USA, and other researchers to take a hard look at what happens in the brain during Hypnosis.

B. Along researchers there are two schools of thought. One claims that hypnosis Fundamentally alters subjects’ state of mind: they enter a trance, which produces changes in brain activity. The other believes that hypnosis is simply a matter of Suggestibility and relaxation. Spiegel belongs to the first school and over the years has had a debate with two Scientists on the other side, Irving Kirsch, a University of Connecticut psychologist, and Stephen Kosslyn, a Harvard professor.

 

D. Spiegel disagrees. One of his best known studies found that when subjects were hypnotised and given suggestions their brain wave patterns changed, indicating that they had entered a trance. In one of his studies, people under hypnosis were told their forearms were numb, then given light electrical shocks to the wrists. They didn’t flinch or respond in any way, and their brain waves resembled those of people who experienced a much weaker shock. To Kirsch this still wasn’t enough to prove the power of trance, but Stephen Kosslyn was willing to be convinced. Many external factors could have been responsible for the shift in the subjects’ state of mind, but Kosslyn wondered,‘Is there really something going on in the Brain?’

E. To find out, Spiegel and Kosslyn decided to collaborate on a study focusing on a part of the brain that is well understood: the circuit which has been found to process the perception of colour. Spiegel and Kosslyn wanted to see if subjects could set off the circuit by visualising colour while under hypnosis. They selected eight people for the experiment conducted at Massachusetts General Hospital. The subjects were put in a scanner and shown a slide with coloured rectangles while their brain activity was mapped. Then they were shown a black and white slide and told to imagine its having colour. Both tasks were then repeated under Hypnosis.

F. The results were striking. When the subjects truly saw the coloured rectangles, the circuit lit up on both sides of the brain; when they only had to imagine the colour, the circuit lit up only in the right hemisphere. Under hypnosis, however, both sides of the Brain became active, just as in regular sight; imagination seemed to take on the quality of a Hallucination.

G. After the experiment, Kosslyn was forced to admit, Tm absolutely convinced now that hypnosis can boost what mental imagery does.’ But Kirsch Remained sceptical, saying, The experiments demonstrate that people are Experiencing the effects of hypnotic suggestion but don’t prove that they are entering a trance.’ He also argued that’ subjects were told to see the card in colour when they were Hypnotised but only to imagine it in colour when they weren’t.‘Being told to pretend you’re having an experience is different from the suggestion to have the Experience.

I. On average, Spiegel and Lang found the Hypnotised subjects used less medication, experienced less pain and felt far less Anxiety than the other two groups. Original results published in The Lancet have been further supported by ongoing studies conducted by Lang.
