Since the beginning of hypnosis, there has been an ongoing debate as to the reality of he process. There are as many individuals who believe that hypnosis is a real state of consciousness as there are individuals who do not believe hypnosis is real. In an effort to prove whether or not a state of hypnosis can be induced, the scientific community has performed its own studies and garnered significant information.
Scientists have subjected individuals to a host of examinations to determine if there are any physiological changes that take place in the body during hypnosis. The results have been interesting and enlightening. After hooking people up to a multitude of machines, scientists have discovered that, although there appears to be little change in the body during hypnosis, the brain itself may experience significant alterations.
Studies have shown that there are few changes that take place in the body during hypnosis. Perhaps the most obvious changes are a drop in heart rate and blood pressure. This is likely due to the state of relaxation that the individual enters when hypnotized. By far the most impressive results of hypnotism are the changes that take place in the brain.
Due to the advent of recent technology that allows scientists to look at the brain during hypnosis, we have been able to actually see the changes that take place during the process. Using Positron Emission Technology (PET) Scans and Magnetic Resonance Imaging (MRI), as well as Electroencephalography (EEG), scientists have watched the brain react to hypnosis, and they have discovered that the brain does experience certain, very real changes during hypnosis.
The use of EEGs have demonstrated that brain waves reflect subtle changes during hypnosis. High frequency brain waves are present during the waking state, and low frequency waves are more prevalent during sleep. During hypnosis, there is an increase in low frequency waves and a decrease in high frequency waves, almost as if hypnosis is a state somewhere between being awake and being asleep.
Brain imaging technologies such as MRIs and PET scans have allowed scientists to view the brain of the subject during hypnosis. These studies show that the left brain, which is generally the center of activity when a person is awake, slows a bit in activity, and that the right brain, generally considered to be the creative hemisphere, shows an increase in activity during hypnosis.
Although these are just preliminary studies that need a lot more research, the results are exciting in that they obviously indicate that the brain is experiencing some sort of change during hypnosis. The alteration of brain waves and brain activity as viewed on EEGs and MRIs, clearly indicates that hypnosis has a direct effect on the human brain, which is exactly the center that hypnosis strives to reach. Further study, including the use of control groups, may target the area or areas of the brain that are being activated during hypnosis. This may further scientific study by giving scientists clearer information as to the function of the brain and what areas perform what functions.
