Hypnosis changes the way our brain processes information -- ScienceDaily

"In a normal waking state, different brain regions share information with each other, but during hypnosis this process is kind of fractured and the various brain regions are no longer similarly synchronised," describes researcher Henry Railo from the Department of Clinical Neurophysiology at the University of Turku. The finding shows that the brain may function quite differently during hypnosis when compared to a normal waking state. This is interesting because the extent to which hypnosis modifies neural processing has been hotly debated in the field. The new findings also help to better understand which types of changes and mechanisms may explain the experiential and behavioural alterations attributed to hypnosis, such as liability to suggestions. The study focused on a single person who has been extensively studied earlier and been shown to react strongly to hypnotic suggestions. During hypnosis, this person can experience phenomena that are not typically possible in a normal waking state, such as vivid and controlled hallucinations.

Hypnotic suggestions can make a complex task easy by helping vision fill in the blanks -- ScienceDaily

The results revealed that participants who were highly susceptible to hypnotic suggestion successfully "hallucinated" visual occluders on top of moving objects. This added imaginary element enabled the participants to better visualize the full geometric shapes and more accurately determine their direction of rotation. On average, their success rate improved to approximately 70%, a statistically significant change.

Exercise boosts tryptophan, a mild hypnotic and serotonin precursor

The largest body of work in humans looking at the effect of exercise on tryptophan availability to the brain is concerned with the hypothesis that fatigue during exercise is associated with elevated brain tryptophan and serotonin synthesis. A large body of evidence supports the idea that exercise, including exercise to fatigue, is associated with an increase in plasma tryptophan and a decrease in the plasma level of the branched chain amino acids (BCAAs) leucine, isoleucine and valine (see64,65 for reviews). The BCAAs inhibit tryptophan transport into the brain.66 Because of the increase in plasma tryptophan and decrease in BCAA, there is a substantial increase in tryptophan availability to the brain. Tryptophan is an effective mild hypnotic,67 a fact that stimulated the hypothesis that it may be involved in fatigue. A full discussion of this topic is not within the scope of this editorial; however, it is notable that several clinical trials of BCAA investigated whether it was possible to counter fatigue by lowering brain tryptophan, with results that provided little support for the hypothesis. Further, exercise results in an increase in the plasma ratio of tryptophan to the BCAAs before the onset of fatigue.64,65

Is Hypnosis All in Your Head? Brain Scans Suggest Otherwise - The New York Times

He said one particularly intriguing finding was that hypnotized subjects showed decreased interaction between a region deep in the brain that is active in self-reflection and daydreaming and areas of the prefrontal cortex involved in planning and executing tasks. That decreased interaction, Dr. Spiegel said, suggested an explanation for the lack of self-consciousness shown by hypnotized subjects.
