When we are talking about science, it is the best way to answer the question, “how?” But it can be confusing when scientists talk about “why?” This word is so true. As you may know, it is the meaning of what Erwin Chargaff a biochemist had quoted a long time ago.
Scientific experiments are so crucial to provide us some useful information. The experiment can vary such as a test to cure rare disease, an observation to natural thing, or others. Of course, experiments are beneficial to provide any information to answer the questions we have today. On the other hands, it can be difficult to understand when scientists did experiments we even did not see its advantage.
Here, we provide you ten scientific experiments that will make you have a big question, why they did this?
10. Keep A Dog’s Head Alive
You may have heard about the use of the guillotine. It was so happening during the French Revolution. Then, it became the beginning of the observations of the possibility to keep a severed head alive. Not long after that, a Soviet physician, Sergey Brukhonenko started to test the theory in the 1920s.
What Brukhonenko used was a dog’s head. He could keep it alive by using a machine he called “autojector”. The machine worked as the heart and the lungs of the dog.
9. “Exciting” A Turkey
Martin Schein and Edgar Hale had a big curiosity about how to excite a turkey. It was in the 1960s and they started to observe turkeys that attempt to mate with a fake female turkey. What they did to start the experiment was creating the life-like female turkey so it looked so attractive.
They also removed the part of the turkey such as the tail, wings, and feet to know whether the turkey was still attracted or not. By the end, the only left was the head on a stick and still, the turkey was attracted and attempted to mate the fake female turkey.
8. Cerberus Minus 1
Vladimir Demikhov wanted to make a new break in the 1950s. He was so popular for his experiment about organ transplants. So, he wanted to learn more, such as creating a two-headed dog. What he did was to attach the front end of a puppy to the neck of the older German shepherd. It was amazing that he had an idea to graft the shoulders and the head. He Also placed the two front paws of the poppy on each side of the other dog’s neck.
For a few days, both of the dogs were able to live, but it was quite short. The tissue was rejected. In fact, Demikhov did this experiment for about 20 two-headed dogs but most of them died within a few weeks.
7. The Cat’s Eye
Dr. Yang Dan was a professional neurobiologist. He wondered about tapping into another animal’s brain t know what this animal is actually seeing. To start his experiment, he anesthetized and chemically paralyzed a cat. After that, he secured it into the surgical frame. He started his experiment at the end of the 1990’s.
To help him see what the cat was seeing, he glued metal posts to the white’s part of the cat’s eyes. After that, he used fiber electrodes and put it into the cat’s brain. The purpose was to control the vision of the cat. Also, he connected the electrodes to a computer to record and transmits the information. After that, he put it into an image.
6. A Homosexual Man
James Olds and Peter Milner contributed their research about the septal regions of the brain. From here, Robert Heath decided to use the information from their experiment and do his own research by adding a little drama. Miler and Olds also found that sensations of the sexual arousal and pleasure are made in the septal region. At this point, it takes something to stimulate the region.
Back in the 1950’s, Heath started the experiment on men. He did not use rats, but homosexual men. His purpose is whether he could stimulate the region of the brain or not. He tried to turn a gay main straight. To do so, he added electrodes into the septal region of the homosexual brain and then controlled the amount of the stimulation. He even made a device to support the “pleasure” and it was known as the “pleasure button”.
5. Face and The Special Expressions
We all know that smile is the sign of happy. A frown means one is sad, and others. It was in 1924, Carney Landis tested a theory and found that there was a special, universal expression all people could make when they experienced shock or disgust.
During his college, Landis took a psychology degree and his subjects were his fellow college student. He even used paint on the face of his subject to get the right readings of facial expressions. At first, Landis used a simple experiment such as asking the subject to smell ammonia. But, the experiment was not the end. He even concluded his experiment by handing his subjects a knife and a live rat. He told them to decapitate it but if the subject refused, he would decapitate the rat by himself.
4. A Human Corpse
Aldini Galvini learned that electricity in the high volts was able to cause the corpse’s limbs to twitch. From here, he tried to shock life. He also used the human corpse. Of course, animals were not the right subjects to do this experiment.
Therefore, it was in 1803 George Forster became the victim, even a murderer. To start, Forster laid out and then various places of his body were full of wires. His body would get 120-volts of electricity to transmit. Eventually, there were wires on the ears and mouth. During this experiment, Galvini noted the jaw muscles moved, and the left eye has opened. It was not the end after Galvini wrapped it up by putting a wire on the ear and then stuck the other in the Forster’s rectum.
3. A Remote-Controlled Bull
It sounds impossible, but Jose Delgado could control his bull through a single press of a button. He did it in 1963. He tried to control his bull’s action through a chip named stimpceiver. He implanted the chip into the bull’s brain and thus, Delgado could control his bull through a remote. In addition, the remote was able to stimulate various parts of the brain, control different behaviors and activities. To test whether it was a big success or not, Delgado stood in the bull-fighting ring. He pressed the button but the bull was uninterested and walked away.
2. The Near-Death Experiment
It was in the 1960s, ten soldiers were sent into the sky on the training flight. During the flight, the main pilot told them that the aircraft had broken and the plane would about to crash into the ocean. When they heard about this and the plane was flying down at the same point, each solder got the insurance form. The form sign stated that the Army had no responsibility in court for any injury or death during the training flight. In the end, all soldiers learned that the plane was fine and they were safe. The goal of the experiment was to know the fear of imminent death could cause soldiers to make more mistakes.
1. The Dying Heartbeat
In 1938, John Deering had volunteered to participate in an experiment to kill him. He did not matter for this one because the fact was he would be executed anyhow. Stephen Besley was the one who did this experiment. It started when a prison guard put the black hood on Deering. Deering got his head covered. After that,m the person guard placed the target on his chest and he would be the one to fire the shot. But, there was an electrocardiogram connected to Deering’s chest to read his hearts beats. Before the shot, his heart was pumping at 120 beats per minute. Once he heard the fire, his heart raced to 180 beats per minute. The electrocardiogram showed that his heart went into the spastic rhythm for about 4 seconds after getting shot four times. His heart then stopped after 15.4 seconds.
