What Are The Physical Aspects Of Hypnosis? Studies have been conducted in which scientists compare the physical signs of hypnotic subjects with those who have not been hypnotized and they have found no significant physical change between those in trance state of hypnosis and those that were not in a hypnotic state. Heart rate and respiration rate were found to be slower, but that is consistent with being in a more relaxed state. What does seem to change regarding physical factors regards the brain activity that is witnessed by electroencephalographs or EEG's. These measure the electrical activity of the brain. Research shows that the brain produces different brain waves depending on the mental state of the patient. Deep sleep waves look different that waves of the person who is awake. Waves of the highly alert person differ from the person who is relaxed. EEG's from those under hypnosis show a boost in the lower frequency waves that are associated with dreaming or sleeping and a drop in the higher frequency waves that are seen in those who are fully awake. This would support the theory that the conscious mind goes on vacation during hypnosis and the subconscious mind takes over. The brain has two spheres or hemispheres of the cortex. During hypnosis it has been shown that subjects have a reduced activity level in the left hemisphere of he cerebral cortex while increasing activity in the right hemisphere. Neurologists (those who study the brain) believe that the left side is where the logical control center of the brain exists and the right side controls creativity. This would support the idea that under hypnosis the conscious mind gives way to the inhibitory nature of the subconscious
