A third state of consciousness could exist, say researchers

A third state of consciousness could exist, say researchers 86

By Bahar Gholipour | MNN 

A new study suggests the existence of a state of mind called dysanaesthesia, which is neither consciousness nor unconsciousness.

With anesthetics properly given, very few patients wake up during surgery. However, new findings point to the possibility of a state of mind in which a patient is neither fully conscious nor unconscious, experts say.

This possible third state of consciousness, may be a state in which patients can respond to a command, but are not disturbed by pain or the surgery, according to Dr. Jaideep Pandit, anesthetist at St John’s College in England, who discussed the idea Sept. 19 at the at an anesthetists meeting in Dublin.

Pandit dubbed this state dysanaesthesia, and said the evidence that it exists comes partly from a recent study, in which 34 surgical patients were anesthetized, and had their whole body paralyzed except for their forearm, allowing them to move their fingers in response to commands or to signify if they are awake or in pain during surgery.

One-third of patients in the study moved their finger if they were asked to, even though they were under what seemed to be adequate anesthesia, according to the study led by Dr. Ian F. Russell, of Hull Royal Infirmary in England, and published Sept. 12 in the journal Anaesthesia.

“What’s more remarkable is that they only move their fingers if they are asked. None of the patients spontaneously responded to the surgery. They are presumably not in pain,” said Pandit, who wrote an editorial about the study.

Normally, while patients are under anesthesia, doctors continuously monitor them, and administer anesthetic drugs as needed. The goal is to ensure the patient has received adequate medication to remain deeply unconscious during surgery. However, it is debated how reliable the technologies used during surgery to “measure” unconsciousness are.

“We don’t have a model for consciousness,” Pandit said. “It is very difficult to design a monitor, to monitor something you don’t have a model for.”

The study of 34 patients was aimed at investigating whether patients are fully unconscious when the monitoring technology commonly used in the operating rooms indicates so. The researchers kept patients’ arms separated from rest of the body, which was receiving routine paralyzing drugs, by blocking the blood supply. Patients were able to move their arm if they were still conscious.

In the patients who responded to the doctor’s command by moving their hand, the doctors took it as a sign of consciousness, and increased the anesthetic dose.

However, Pandit argues these patients were not “conscious.” The fact that patients only responded to command, and didn’t move spontaneously shows their state of mind is different from normal consciousness, he said.

Research confirms that “near death experience” is not an illusion

Research confirms that "near death experience" is not an illusion 99

Dr. Alexander Batthyany, a professor of psychology at the University of Vienna, has studied thousands of cases of near-death experiences. Human thinking ability has nothing to do with the brain.

Near death experience case study

Dr. Batthyany and others collected thousands of complete cases describing near-death experiences , and recorded in detail the content of the near-death’s private prosecution and doctor’s consultation.

Doctors ask dozens of questions about what the patient sees (visual), what he hears (hearing), what he thinks (consciousness and thinking), life background (such as religious beliefs, life experience), etc., such as “Have this experience before Do you?”, “Do you see the light?”, “Who do you talk about your death experience?”, “Do you believe in your death experience?”, etc., to judge and evaluate the credibility of the patient’s narration of the near death experience Degree and the patient’s mental state after death (whether normal, etc.).

Dr. Batthyany said that the results of the study are reliable and fully confirm that the near-death experience is a real mental activity rather than an illusion. He also said that research methods have certain limitations, which will lead to underestimation of the proportion of near-death experiences.

Extremely credible near-death experiences

Dr. Batthyany explained that due to the limitations of the method, cases are likely to be missed, so the actual rate of near death experience should be higher.

Dr. Batthyany explained how he and his colleagues analyzed thousands of cases by compiling and integrating medical records into a resource library (such as the NDERF website), and then using search terms related to vision (vision) or cognition (such as “See” (saw) or “thought”> search for related medical records and score them according to visual or cognitive content, and then further narrow the scope of the study, such as selecting near-death experience cases with detailed medical records. This screening method based only on search terms is likely to miss cases where there is no such vocabulary in the expression.

Dr. Batthyany said that the near-death experience cases are highly credible. They considered that thousands of cases with near-death experiences are likely to have false reports, but in the process of sorting and analyzing, they noticed that only 1% of near-death cases were deleted due to validity.

Therefore, Dr. Batthyany believes that even if there are still false cases, the number is not enough to affect the overall conclusion.

Evidence of the phenomenon

In addition to these near-death experience studies, Dr. Batthyany also pointed out that the phenomenon of back light also shows that the phenomenon of thinking consciousness is extremely complex, even in the case of severe deterioration of brain function, there can be active thinking.

Dr. Batthyany studies the back-to-light phenomenon in patients with Alzheimer’s disease. Among patients with Alzheimer’s disease (ie, Alzheimer’s disease), some people have been completely incoherent for many years, but suddenly showed a marked improvement or normal thinking shortly before their death. This is what is commonly referred to as “return to light”.

According to the current neurological concept, as the brain function of Alzheimer’s patients gets worse and worse, their thinking performance should be that their memory and various thoughts and feelings are becoming more and more lost, and there is even no human thinking at all.

However, the actual situation is just the opposite. The whole state of mind of Alzheimer’s patients may suddenly become intact like a spark burst.

“Psychological Vision” of the Blind

In fact, there is also a phenomenon of “mindsight” or “mind intuition” which also illustrates the independence of thinking. “Psychovision” refers to the sight of a blind person who reports during a near-death experience.

Kenneth Ring of the University of Connecticut found that among 21 blind cases who reported near-death experiences, 15 blind people described seeing the scene and had vision.

Dr. Batthyany pointed out that some scientists believe that near-death experiences are hallucinations produced by human neurophysiological processes. However, “in this study, the results of near-death experience, rebirth, and psycho-visual phenomena suggest that patients experience near-death experiences when their condition deteriorates, die, or have no neurological activity, and it is common.”

Therefore, Dr. Batthyany concluded that even when the brain function changes or even the electrical activity of the brain stops (the EEG is flat), there is still a clear sense of self, complex visual images, and clear mental activities. And other thinking phenomena.

Even though back-lighting and psychological vision are very rare phenomena, the countless examples of near-death experiences are enough to illustrate the problem.

Dr. Batthyany wrote:

“Our research results show that the visual scene, mental state and self-awareness that people continue to appear in the near-death experience are a rule rather than an exception.”

What people see after clinical death: Stories from survivors that they would rather forget

What people see after clinical death: Stories from survivors that they would rather forget 100

Humanity still does not know much about death. Of course, it’s easy to write it off as “nothingness,” but what if in reality everything is a little more complicated? In the selection below – ten creepy stories “from the other world” from people who survived clinical death.

Recently, the user Aidanmartin3 asked near-death survivors on Reddit to describe what it was like. The post quickly went viral, with hundreds of people sharing their stories in the comments.

I was about fifteen years old. Climbed onto the kitchen counter to grab something from the top cabinet, but slipped and fell headlong onto the marble floor. The next thing I remember is walking barefoot on water. Then I look to the right, I see a very bright light and a hand, as if calling me. I go to her and suddenly realize how peaceful and relaxed I am. Like the best deep sleep ever. Then I said to myself: “Dude, this is so cool, I would never wake up.” And then all of a sudden everything disappears, and I wake up because of my mother, who is crying over me.By that time, I was already numb, cold, pulseless and even managed to urinate in my pants. As an atheist who does not believe in all this, I often think about that case.

My father died for a short while and then said that at that time he was walking along a long corridor to the door. But when he was about to open it, his father felt himself being “sucked” into his own body

He died of an overdose for several minutes.In reality, there was nothing. It’s just darkness and an incomprehensible period of time. It was almost like waking up after hanging out all night and feeling like a horse kicked in the chest.

It seemed to me that I was kind of floating in a long tunnel and I felt very tired. I remember how I fell asleep then and had a dream that I was in the kitchen of my childhood home, and dad was preparing breakfast. I heard turmoil and chaos at one end, and at the other, there was a warm light that seemed soothing. But then all of a sudden I ended up in the chaos of the emergency room.

The story of my ex-girlfriend’s mom. Her heart stopped for 28 minutes. The doctors had already told the family that she had left, and even brought in a priest to bless the room. But in the end she returned. She said that she recalls running around the field with a little girl, who, according to the woman, was her niece, in the dress in which she was buried.

I heard a loud, high-pitched noise telling me that I am still too young to die. Then he got even higher, and I saw a bright light and woke up. The ambulance driver was shining a flashlight in my eyes

Anaphylactic reaction to the deadly sting of the Irukandji jellyfish. I saw this white glow and how I soared up, then my family and the doctors and nurses who were saving me. Came back and felt a lot of pain

It felt as if my body was being filmed on a CCTV camera from a third person. Then the camera gradually moved away and rose. I became very cold and began to hear loud clanking sounds. Woke up in an ambulance to the sound of a gurney bouncing on a rough road. It was so surreal. Since then I have not been afraid of death, to be honest. It was almost six years ago, but I still think about that case several times a month.

I was hit by a car. I could see everything, blood had not yet got into my eyes. I heard all the commotion. I felt myself being pushed in the back, and then doing artificial respiration … After that I felt only the first beats of the heart and how the blood flowed through my body. The pain began to build up with renewed vigor, and then everything went black

I was pronounced dead three times. But “after death” I have never seen anything. At least i don’t remember

Psilocybin mushrooms sprout in the blood of an ‘experimental’ patient

US doctors described the story of a man who tried to relieve depression with psilocybin mushrooms in an unconventional way. He injected an intravenous infusion of mushrooms, causing the mushrooms to continue to multiply in his blood and cause multiple organ failure. The case was reported in the Journal of the Academy of Consultation-Liaison Psychiatry.

Many drugs that people traditionally use as psychedelics are increasingly becoming the focus of medical attention. Some of them have already been repurposed and started clinical trials: for example, micro-doses of LSD have proven to be at least safe in the case of Alzheimer’s disease, and psilocybin has helped patients with  migraines and  depression. Often in such experiments we are talking about microdosing – that is, the mass of the substance is not enough for a psychoactive effect.

The story of an American who decided to experiment on his own was described by doctors led by Curtis McKnight of Creighton University School of Medicine. According to relatives, the 30-year-old American suffered from bipolar disorder, but shortly before the incident stopped taking his prescribed medications and suffered from alternating states of mania and depression.

When he stumbled upon research on the potential benefits of psychedelics, he boiled psilocybin mushrooms and injected the filtered solution into his vein. A few days after this experiment, relatives found him in a lethargic state with jaundice, diarrhea and bloody vomiting and took him to the hospital.

Doctors discovered the patient had a problem with multiple organs at once: acute renal failure, liver damage, tachycardia, and low blood saturation and ionic imbalance. He was prescribed droppers to normalize the composition of the blood, vasoconstrictors to raise blood pressure, antibiotics and antifungal drugs. Despite this, he developed septic shock and DIC (excessive blood clotting) and needed plasmapheresis. Only eight days later he was discharged from the intensive care unit, and at the time of publication of the article he had already been in the hospital for 22 days.

In the patient’s blood tests, in addition to the Brevibacillus bacteria , there were also Psilocybe cubensis fungi  – the same ones from which he injected himself intravenously. Apparently, due to insufficient filtration of the solution, the fungi entered the bloodstream and multiplied there, causing intoxication and multiple organ failure.

The authors of the work note that this is not the first such case – at least in the 80s of the 20th century, doctors already described a patient with similar symptoms after an intravenous injection. Therefore, McKnight and coauthors warn their colleagues: since psychedelics are increasingly used as a medicine (at the end of 2020, they began to legalize it in the United States), it is important to remind patients of the inadmissibility of self-therapy. Intravenous administration can be dangerous – doctors still do not know if it has the same psychoactive effect as the classical methods of administration.
