"Though they really true to false, inaction Department has also not" some people speak half-truths, falsehoods, making it difficult to distinguish, however, did not always get "woolly-headed," the word to stall , very often, especially when it comes to important events, we need to know the truth behind the language of the other side. Chinese saying goes, "wine there is truth" Similarly, in ancient Rome had a similar theory - the truth in wine, so people began to consider, there is no such a thing, people will eat it tell the truth?
Study veritaserum medicine dates back to 1916, there was outside in Dallas obstetrician Robert? House, when he was out for the birth of a woman, in order to reduce the pain experienced by mothers surgery, Robert to mothers injected with scopolamine, which is an extract from a plant in the scopolamine base, it can block the neurotransmitter - acetylcholine play a role in the body will be in a semi-anesthetized state.
After birth, the doctor let the House, said the child's father to find child weighing, yet careless father says forget where home resting, looking for a good while but have not found, then the surprising scene took place : under anesthesia maternal spoke, precisely out of said position. This happened to cause the House doctors thought he believed in the role of mothers is scopolamine speak of, that is to say after the administration of scopolamine, who will give the true answer to the question in the unconscious state.
In fact, long before the House physician, obstetrician Germany have discovered a similar phenomenon, injected morphine or scopolamine mothers who can not help but begin to describe the details of his former life, but only the House doctor keenly phenomena and veritaserum linked to together, and began promoting the drug in the forensic science.
From the 1920s to the 1930s, this decade, in order to allow the suspect to tell the truth, in addition to scopolamine, US police also try to use proper spray and sprinkle amytal and other barbiturates and other drugs, through elimination the weak part of the brain activity, to eliminate its inhibitory effect, people involuntarily opening to achieve results. However, the actual outcome no way confirmed, to the 1950s, since these drugs can not be proved to have medication can induce to tell the truth and the effect was negative and many scientists questioned by most US courts no longer spit the real drug to obtain testimony.
But this did not stop people from pursuing truth serum drugs pace, but because truth serum drugs relates to other aspects of military intelligence, countries are tight-lipped, many things unknown. But there are rumors that there is a colorless, odorless and will not appear immediately side effects of drugs - "SP-17", the KGB had used Veritaserum efficient, more amazing is that medication only know in hindsight suddenly fall asleep , and does not remember what happened, not to mention their own time to say something. "SP-17" is used to examine the degree of loyalty spies, however, the rumor is true or it is unverifiable.
In film and television works, Veritaserum is popular, not to mention the "Harry Potter" in the magic world inside Veritaserum film "Kill Bill 2", "True Lies" depicts the real world, also appeared veritaserum drug figure, you want to know the truth, a truth serum drugs is enough.
Veritaserum drugs really so magical?
In fact, in general, truth serum drugs is tranquilizers, mainly human interference judgment and higher cognitive function. Because lying is a more advanced and complicated brain activity, after the drug is injected, the human brain is "paralyzed", lying capacity will decline, and that there have to ask the question, will not remain silent, said much more information big naturally easy to set out the truth. However, scientists believe that under Veritaserum Herbs, a person may also lie. Furthermore, for people with mental disorders, truth serum drugs completely ineffective, because of mental illness patients with visual hallucinations auditory hallucinations and imaginary memories, mainly caused by brain lesions, therefore, for these "false", they themselves are convinced . Then we need other assistive technology to help identify the authenticity of. (Author: Zhang Lianmin)
