If you believe that the soul, leaving the body, makes a «quick look at life» and «sees the light at the end of the tunnel», then you will be interested to know what the experts think about this. How do experts look at NDE: near-death experiences, near-death experiences?
First. People near death or those who thought they were dying, in the event of a return to life, usually cannot boast that they «saw» or «felt» anything. At best, one out of ten reports this, and usually these are people “informed” who have somehow heard about what “happens” at death.
Second. Conditions similar to NDE often occur in people in situations that have nothing to do with clinical death. Such conditions are experienced, for example, by fighter pilots when the aircraft unexpectedly enters a dive and undergoes rapid acceleration. Drug use (hashish, LSD, or DMT) produces psychosis and similar experiences.
Third. NDE is caused by neurophysiological interference in the human brain. All of the above experiences in a person confidently arise with electrical stimulation of the temporal lobe in the transition to the hippocampus, a high level of carbon dioxide (hypercapnia), and a decrease in brain perfusion as a result of local hypoxia of the brain. Actually, the latter is analogous to the effect of rapid acceleration in the course of training fighter pilots. It is interesting to note that when such visions occur in a person during a regular operation, no “existential changes” occur in people: the understanding of life does not change, the fear of death does not disappear …
Fourth: ketamine. Ketamine is widely used in surgical operations as a cheap and relatively safe anesthetic and short-acting analgesic. A patient who has been injected with ketamine experiences such a strong alienation and withdrawal from his body that he can be operated on without anesthesia. But under ketamine, the patient, as if spellbound, easily sees himself from the side, above the operating table, his memories from the past flare up, he can easily see the light at the end of the black tunnel, hear strange enchanting sounds and experience ecstasy when communicating with God … Well, yes, ketamine , although not an opioid, but similar to LSD and mescaline blocks NMDA receptors along with endorphin, serotonin and enkephalin. However, if a patient is given sedatives along with ketamine, the patient calmly loses consciousness and no longer suffers from any mysticism.
Fifth: check everything. University of North Texas professor Dr. Jana Holden attaches a laptop during an operation on the ceiling, directly above the patient’s head. As soon as the patient dies, the laptop screen starts broadcasting a series of memorable images, which her husband developed especially for this experiment. If the patient after the operation tells that his soul flew out of the body, flew around the operating room and saw everything from the outside, then she will surely see bright, blurry pictures on the laptop screen. These experiments have been going on for many years, several doctors are participating in them, but so far, unfortunately, there are no interesting results …
