Consciousness On-Off Switch Discovered Deep In Brain
An anonymous reader writes "One moment you're conscious, the next you're not. For the first time, researchers have switched off consciousness by electrically stimulating a single brain area. Although only tested in one person, the discovery suggests that a single area – the claustrum – might be integral to combining disparate brain activity into a seamless package of thoughts, sensations and emotions. It takes us a step closer to answering a problem that has confounded scientists and philosophers for millennia – namely how our conscious awareness arises. When the team zapped the area with high frequency electrical impulses, the woman lost consciousness. She stopped reading and stared blankly into space, she didn't respond to auditory or visual commands and her breathing slowed. As soon as the stimulation stopped, she immediately regained consciousness with no memory of the event. The same thing happened every time the area was stimulated during two days of experiments.
That sounds like the experiments that my wife has been doin

Football fans everywhere are celebrating. How long till they incorporate this into a tv remote? Perhaps we can just reprogram the mute button?
I see lots of new and exciting things happen in the world of neurology and such. Are these things directly stemming from the Human Brain Project? How do we know what successes have come out of that program?
So we have a bunch of male scientists who apparently didn't know about rufies.

..is basically the main() function for humans.
so, any idea how long your brain just went off?
But needs deep brain electodes so I guess it wont be easy to pull off .. But with advances in implant devices , zzz (shivers )
Neat. Could be used during surgeries instead of anesthesia, or could be weaponized to disable enemy combatants.
If it can be employed in surgery (putting aside the current implant requirement) it would be a surgical boon (might not be so good for anesthesiologists ;>)
"a homosexual in a gay bar" so that would be most of the people there?
Be nice if this could work as anesthetic.
An on/off switch on women!
Wow, if we discover the exact region and mechanism for how consciousness emerges from brain activity, then this, in my mind, is the final nail in the coffin of the Soul Hypothesis ( the religious explanation for consciousness being external to the brain, and as something that survives death ).
Of course, the religionists will carp on about how this study is all a big conspiracy with science finding or some other claptrap, but for the rest of us, this could be a major discovery!
One step closer to the zombie apocalypse.
I particularly liked the manner in which the writer jumped from something as complex as the human brain developing consciousness to wondering if robots have the same function. He should be lobotomized.
From TFA:
Anil Seth, who studies consciousness at the University of Sussex, UK, warns that we have to be cautious when interpreting behaviour from a single case study. The woman was missing part of her hippocampus, which was removed to treat her epilepsy, so she doesn't represent a "normal" brain, he says.
Normally a scientist will not ethically be able to put deep brain electrodes in a person, but this was likely part of a larger experiment related to the hippocampus surgery. It will be interesting to see if similar cases present similar behaviors and more interesting if the same thing happens in someone with a full hippocampus.
Does anyone find the fact that she was not respondant to auditory and visual stimuli, but still breathed(even though it slowed down)?
it's as if the survival instinct overrode the unconsciousness
I have been experimenting with this technique since the early 80s. It is possible to stimulate the claustrum via pressure along the sternocleidomastoid. By pinching this area it causes sympathetic nerve activity that can effective render someone unconscious. My colleague has perfected the technique to the point that he uses it at parties. Quite eerie, actually.
Peace. Stay healthy and have a long life..
Yeah, but the surgery is (usually) gonna hurt like blazes the instant the signal is stopped!
Cloned foods give the statement "We had that last week!" a whole new meaning.
Ever heard of "Pause"? LOL

I thought that if you're stimulating a woman's claustrum and she falls asleep, you're doing it wrong.
It begins with the words "Cardholder's agreement".
Whenever survival is at stake, consciousness is among the first wasters of valuable resources (energy) to be turned off, or at least substantially modified.. This is a principle, AFAIK.
They zapped a part of her brain that had the effect of stopping conscious thought. I suppose that meets the definition, but it sounds more like they overwhelmed her normal brain function rather than shut it off.
Now they have a way to keep clones unconscious until they harvest organs from them.
OTHO, I wonder if it could be used during surgery in place of drugs?
Direct access to unconsciousness brain part ?
What is next ?
- flashing new ideas/learning skills like Neo.... or brainwashing/propaganda...
- or cheap and instant medical anesthesia, nonlethal cop weapons, alternative to rape drugs...
- clearing out what is in your consciousness and not in your long-term memory yet, like in Men-in-Black...
Choose one. Ok, all.
Imagine what could happen if it were conveniently located on your back!
Ezekiel 23:20
These studies clearly demonstrate that the Cl is richly innervated with a wide and diverse array of neurotransmitters and neuromodulators. Lesion, stimulation and recording experiments demonstrate that the functional and physiologic capacity of the Cl is quite robust. A recurring theme of claustral function appears to be its involvement in sensorimotor integration. This may be expected of the Cl, given the degree of heterotopic, heterosensory convergence and its interconnectivity with the key subcortical nuclei and sensory cortical areas. The Cl remains a poorly understood and under investigated nucleus.
It makes sense that a major loss of function is associated with interrupting the Claustrum - but there are several nuclii in the brain - the Hippocampus being one. Claiming it is the 'one true center of consciousness' in the brain doesn't account for the countless studies which reveal just how complex the operation of our neural networks actually are, and may be premature.

So, how well does this finding fit with the Integrated Information Theory of Consciousness?

this is like MKULTRA experiments. the damage done to people from mind control experiments is long-term. this women is going to wake up one day and realize she couldn't even remember if she forgot anything. she might suddenly die. she might lose hair or teeth.
maybe she gets schizophrenia or multiple personality disorder. this is common with mind control subjects. like the 10 year olds abducted by the military, raped, drugged, electroshocked, kept in cages, psychically drived, and trained as prostitutes and spy assassins... then suddenly kicked out of the program and suffering extreme injury for the rest of their lives.
I fear for the womens life because what these doctors are doing to her are fucking batshit crazy.
This actually happened to me as a male at age 23.. read my site.

I'm pretty sure I've seen devices like this in science fiction shows. Though absent a very high quality auto-targetting, I can't see the real one having any use against an unwilling subject. I wonder if it also causes short-term memory loss?

Let me guess, results of yet another publicly funded research have been stolen by those parasites at Elsevier...
"When the team zapped the area with high frequency electrical impulses, the woman lost consciousness. "
Tazers!
Having seen someone faint at the sight of blood (the lights went out instantaneously and they hit the floor like a sack of potatoes) this woman's experience doesn't quite match what I saw. The woman seemed still to have muscle tone to remain sitting upright. So this suspension of some sort of executive control/awareness/conscious experience needs a different name.
The NewScientist article said "To confirm that they were affecting the woman's consciousness rather than just her ability to speak or move, the team asked her to repeat the word "house" or snap her fingers before the stimulation began. If the stimulation was disrupting a brain region responsible for movement or language she would have stopped moving or talking almost immediately. Instead, she gradually spoke more quietly or moved less and less until she drifted into unconsciousness."
So, she wasn't having conscious experience but wasn't unsconscious. The NS article also talked about being awake but unconscious, which doesn't fit the sack of potatoes unconsciousness.

Table-ized A.I.
Where does the soul end and where does the funk begin?
Consciousness or memory of consciousness?
Girl: Did I fall asleep?
Doctor: For a little while.
Girl: Shall I go now.
Doctor: If you like.
Turns out that a lot of people, if you hit them on the point of their chin they lose consciousness. Most will lose consciousness with a simple tap to the temple. Seems like an easier off-switch to me.
We've finally found a way to "turn off" our wives...
I got hit by a motorcycle riding my bmx bike when I was a kid. Completely blacked out before impact. Turns out I had no injuries at all, not a single scratch, the motorcycle actually hit my front tire. I was out cold for over 5 minutes and awoke on the side of the road having no idea where I was or why I was there. A guy behind the motorcycle stopped and pulled me off the road. Guy on the motorcycle kept going. I wouldn't have even known I got hit if the other driver would not have told me, and the fact my rim was only half round.
This reminds me of what the locals from Colombia refer to as the devils breath. Pretty scary.
so they figured out a way to poke someone's brain and render them unconscious?
I bet I can do the same with any processor, just poke it somewhere with a metal piece and make it stop working.
Am I missing the point?
It turns out that self-awareness is an illusion of a couple of smallish blobs in your brain, without which you would be no smarter than the average computer? Seems like it ought not to be terribly difficult to make a computer think it's self aware too, then.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
The only evidence that remains is whatever isn't cleaned up [or any resulting youngins]
Perhaps they could use this information to try an investigation of how anesthetics work with a narrower scope, giving them a chance for a better understanding of what goes on with those drugs and the ability to make future anesthesia less dangerous.
Won't have to guess at dosage anymore, just zap the brain until you want them to wake up. Of course, there needs to be redundancy so they don't wake up screaming.
Is responsible for creating consciousness INSIDE claustrum?
Forget the comedy - this might be an invention that could make long distance flying bearable! Turn off your brain after take off and back on for landing with no memory of many hours of sitting in a tin can in between.
There have been a lot of people with head injuries who have fallen into coma - would electric zaps into the claustrum regions within their brain revive them ?
Perhaps they find out that people have different lengths and sizes of the 'claustrum' and find a correlation between attention span or concentration or something AND then maybe 50 years later they find out that none of that really mattered.
Think ( while you can ) at just how much this could be abused.
Thought: sleep learning/hypnosis. So can we put someone in an unconscious state, put suggestions in their head wake them and voila, brand new religious zealot?
"Consensus" in science is _always_ a political construct.
Yes, expect this project to be transferred to military control. Who will devise a mechanism to broadcast this signal en masse. The government's wet dream, the ability to shut down instantly all humans at will.
No more combatants, no more riots, just turn them off...
"I would liken it to a car," he says. "A car on the road has many parts that facilitate its movement - the gas, the transmission, the engine - but there's only one spot where you turn the key and it all switches on and works together. So while consciousness is a complicated process created via many structures and networks - we may have found the key."
Phasers on stun.
I don't find abuse that requires someone to secretly perform brain surgery on me very scary.
if everyone had one of these installed, police would be able to remotely 'deactivate' anyone who was in the process of committing a crime. couple it with a bit of personal information for identification and this could even be used to remotely deactivate someone over a 911 call. tech glasses could give you the persons name + id and you could inform the dispatcher of this and have the threat handled in a matter of seconds instead of minutes. could also make dealing with mental illness much easier.
Doctors have known this since the early 20th. There are several "prerequisites" to consciousness. One of them is a functioning RAS (Reticular Activating System). They have drugs to make you "unconscious" by acting on this part of the nervous system. I suppose on the Internet, things can be discovered over and over again.
I am curious if this insight will modify the manner in which some types of epilepsy are diagnosed.
There are different types of epileptic seizures and not all of them cause a person to lose consciousness. Partial seizures only affect a section of the brain at a time, while generalized seizures affect the entire brain. And from what I understand, some medications prevent different types of seizures better than others. If a person can completely lose consciousness by stimulating this small area of the brain, I wonder if some people diagnosed with a type of generalized epilepsy are actually having partial seizures around the claustrum. If so, and if tests could confirm this, then some people may receive more effective medication.
We've been living in that world for the past thirty years or so, from what I've seen. It's hard to recognize it, because, well... they're using the technology on us all the time.
You don't need wires to stimulate deep brain regions. I read a similar story about cognition where the doctors mentioned in an off-hand way that they used a type of microwave beam to non-invasively stimulate a region of the brain to turn on and off eyesight. (wtf???) -Like such a feat was no biggie, completely beside the point. They were all excited about some minor observation about memory and attention or something. The huge significance of the fact that they were using a piece of industrially available medical equipment to temporarily blind people with the flick of a switch appeared to be entirely lost on them.
On a subtler level, you can direct emotional states and cognitive acuity at both key or prolonged moments with microwave technology. Virtually everybody walks around with a cell phone attached to their bodies.
Of course, those most plugged in are least willing or able to recognize this.
This is pretty cool, and has some implications on inducing lucid dreams. I can't wait until this becomes a more refined process, would be awesome to lucid dream at will. Certainly something I'd pay good money for.
without reading too much it sounds more and more like they found a way to put a human to sleep by inhibiting cross-talk in the brain; for example... it looks to be more similar to suffocation than the utility of the lungs themselves
It would be interesting to see if this could be used as a replacement for surgical anesthesia. If so, no more adverse side effects, or the attendant risks that general anesthesia comes with.
