Maybe you've heard of the things people have "automatically" done under Ambien?

In a sleepwalking state, they can go out driving, iron clothes, cook and eat meals, all manner of things that we'd assume needed conscious thinking. It's perfectly possible to say, ride a bike while thinking about something else, or handle any repetitious task that we learned before with an empty head, but the Ambien stories suggest that fairly complex behavior can be automated.

There's a type of treatment called dissociative anaesthesia, where the person stays conscious, can answer questions, follow directions, and tolerates surgery comfortably. Neuroleptanalgesia, it's called.

Haiti practitioners use toad venom to induce a zombie state, which is pain tolerant, fatigue resistant, and hypersuggestible.

But that's chemical changes to the brain. We can measure that.

So how does hypnosis work? Anybody know?

AFAIK hypnosis doesn't work outside of fetish dreams...

You cannot change neurochemistry at will. Not even you, yourself, let alone someone else telling you to.
You need drugs to do that.

It is just the power of suggesting and how it is applied.

Most advertising, uses hypnosis to sell things. To the point that some aspects are banned.

Hypnosis can only affect some people, and even then it can't make anyone do anything they wouldn't normally do. It's a bit like have someone encourage you to do something, if you want to do it the encouragement helps, if you don't it won't. Essentially helping lower conscious inhibitions or barriers to allow or prevent certain actions. Like stopping smoking, it still takes will power.

Only money!

I've had hypnosis tried on me. The practitioner gave up when I told him to frell off.

It's garbage.

Certainly, there's going to be people with a very high resistance to hypnosis.

I can see how it can switch off psychic pain components, so that the self-conscious pain of embarrassment goes away, and you can pretend to be a chicken in front of people more freely. ( You know it's stupid, but you no longer care - like a passive neuroleptanalgesia patient saying "I feel the needle in my eye, and it is uncomfortable, but go ahead")

Stanford scanned people under hypnosis.

This decrease in functional connectivity likely represents a disconnect between someone’s actions and their awareness of their actions, Spiegel said. “When you’re really engaged in something, you don’t really think about doing it — you just do it,” he said. During hypnosis, this kind of disassociation between action and reflection allows the person to engage in activities either suggested by a clinician or self-suggested without devoting mental resources to being self-conscious about the activity.

It's kind of like the no-mind state in the Last Samurai, maybe?

i bet it induces chemical changes in the brain? i never have had an hypnosis experience, but i know for sure that you can alter your brain without any external chemicals, just modulating your mood or state of mind. quite easily, actually, and we do it all the time. hypnosis could be just a notorious case of that.

Yep, just fantasize very vividly about someone you really fancy and feel those chemical changes in the brain and resulting physiological changes kick off, baby.

Oh, and whatever you do, do not think about giant pink elephants with purple spots.





It's just tacky.

I'm not a Dr. but will tell what I know.

There are measurable brain wave states which relate to levels of alertness and also relaxation.

When hypnotised a person will be induced into the relaxed forms of these states by triggers such as, context, tone of voice, suggestion, and engaging imagination.

There are three levels of depth, which can be measured as a person enters them by changes in metabolism, temperature and pulse rate.

In these states certain people will be more open to suggestion, amongst other things.

A person who is susceptible to hypnotism can be identified by asking then them to close there eyes and stand on the left leg, a person who is more prone to hypnotism will find it hard to balance.

To introduce a subject; you have to have them at a kind of sleeping state. More akin to that point, just before you doze off. Like that moment, just as you are about to cross the centre line of the road and a trunk is coming the other way. Then you basically, hold them there and 'suggest' what you like. Good luck with that part, because, the subject, IS still aware.

first, that movie is total rubbish :D

anyway what is meant by that is to free the mind of distractions and worries so you can react calmly and spontaneously with the best efficiency possible. medieval japanese got that a step further and instilled (via education and social pressure) disdain even for one's own life, since that's probably your biggest worry when you are in battle. so they convinced themselves to be already dead and have nothing to loose, nothing to worry, just kill. ironically, relinquishing your life may be your best bet for survival. it makes sense and, apparently, it worked.

i've read somewhere about some military experiments with some form of waves aimed to shut down specific activity in the brain. subjects made record scores in shooting experiments, and even reported the experience to be incredible, even addictive. it's the same principle.

so it's not hypnosis, but a way to control/manipulate the brain.

[h=3]Neuropsychology[/h]Changes in brain activity have been found in some studies of highly responsive hypnotic subjects. These changes vary depending upon the type of suggestions being given.[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-168"][168][/URL][URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-169"][169][/URL] The state of light to medium hypnosis, where the body undergoes physical and mental relaxation, is associated with a pattern mostly of alpha waves[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-170"][170][/URL] However, what these results indicate is unclear. They may indicate that suggestions genuinely produce changes in perception or experience that are not simply a result of imagination. However, in normal circumstances without hypnosis, the brain regions associated with motion detection are activated both when motion is seen and when motion is imagined, without any changes in the subjects' perception or experience.[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-171"][171][/URL] This may therefore indicate that highly suggestible hypnotic subjects are simply activating to a greater extent the areas of the brain used in imagination, without real perceptual changes. It is, however, premature to claim that hypnosis and meditation are mediated by similar brain systems and neural mechanisms.[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-172"][172][/URL]
Another study has demonstrated that a colour hallucination suggestion given to subjects in hypnosis activated colour-processing regions of the occipital cortex.[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-173"][173][/URL] A 2004 review of research examining the EEG laboratory work in this area concludes:
Hypnosis is not a unitary state and therefore should show different patterns of EEG activity depending upon the task being experienced. In our evaluation of the literature, enhanced theta is observed during hypnosis when there is task performance or concentrative hypnosis, but not when the highly hypnotizable individuals are passively relaxed, somewhat sleepy and/or more diffuse in their attention.[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-174"][174][/URL]
​
Studies have shown an association of hypnosis with stronger theta-frequency activity as well as with changes to the gamma-frequency activity.[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-175"][175][/URL] Neuroimaging techniques have been used to investigate neural correlates of hypnosis.[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-176"][176][/URL][URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-177"][177][/URL]
The induction phase of hypnosis may also affect the activity in brain regions that control intention and process conflict. Anna Gosline claims:
Gruzelier and his colleagues studied brain activity using an fMRI while subjects completed a standard cognitive exercise, called the Stroop task. The team screened subjects before the study and chose 12 that were highly susceptible to hypnosis and 12 with low susceptibility. They all completed the task in the fMRI under normal conditions and then again under hypnosis. Throughout the study, both groups were consistent in their task results, achieving similar scores regardless of their mental state. During their first task session, before hypnosis, there were no significant differences in brain activity between the groups. But under hypnosis, Gruzelier found that the highly susceptible subjects showed significantly more brain activity in the anterior cingulate gyrus than the weakly susceptible subjects. This area of the brain has been shown to respond to errors and evaluate emotional outcomes. The highly susceptible group also showed much greater brain activity on the left side of the prefrontal cortex than the weakly susceptible group. This is an area involved with higher level cognitive processing and behaviour.[URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-178"][178][/URL][URL="https://en.wikipedia.org/wiki/Hypnosis#cite_note-179"][179][/URL]

Taken straight from Wiki here:

I would also look at meditative trances and Hypnagogia:

........ for similar neurochemical, neurophysiological and psychological paradigms.
