Hypnosis is used to distract and divert one's attention. Self-hypnosis and autosuggestion are also techniques used not only in ''positive thinking'' approaches but also in some versions of self-guided meditation [Z:352-355].
A very relaxed state was induced by hypnosis in eight subjects who had been selected for their high degree of hypnotizability. PET scan activity increased in both the inferior and middle occipital regions (BA 18 and 19). So too did the subjects' occipital delta EEG activity.13 Why delta?
It was speculated that this increased occipital PET activity, associated with delta EEG activity, might be related to an innate tendency of the more highly hyp-notizable subjects to develop higher levels of visual imagery, or to the unusually deep relaxation they could reach during hypnosis.
Other PET scan activities also increased: in the right superior temporal gyrus (BA 38 and 22), the caudal part of the right anterior cingulate sulcus (BA 24), and the left inferior frontal gyrus (BA 44). Decreases occurred in the precuneus on both sides (BA 7), the left posterior cingulate gyrus (BA 31), and the right inferior parietal lobule (BA 40/7).
In the early history of hypnosis, pain control often played a prominent role. Pain control was addressed in a second part of this same study. Painful stimuli were generated by immersing the subjects' left hands in hot water (47°C). Under hypnosis, verbal suggestions were made that this pain was going to become more severe or less severe. The hypnosis with suggestions of pain relief produced other widespread increases in PET activity. These occurred more in the left hemisphere.

HYPNOTISM is by no means a new art. True, it has been developed into a science in comparatively recent years. But the principles of thought control have been used for thousands of years in India, ancient Egypt, among the Persians, Chinese and in many other ancient lands. Learn more within this guide.
