9 - Hot Chicks Only
In 2002, a group of scientists decided to do research on chickens. Because of course, that’s one of Denmark’s biiiiigessssst priorities.The team of scientists decided to test what chicken’s preferences were for human faces. Seriously. Why they needed the answer to that question, we’ll probably never know, but hey, we’re sure someone will put the results to use! Scientists have known for years now that chickens can recognize up to 30 other individual chickens. But what about recognizing human faces? The scientists trained chickens to react to either an average human male or female face. They then showed the chickens a series of faces of different levels of attractiveness and measured how much the chickens pecked at each face. Surprisingly, they found that the chickens preferred the same faces as did human volunteers who participated in the study! The chickens pecked more times on the most symmetrical faces. Human volunteers were asked to rate the same faces for attractiveness. So it turns out that chickens are more shallow than we would have guessed, but hey, maybe this suggests that the team over at Tinder whose helping us pick the best photos for our profiles are just teams of chickens!
8 - On-off switch
The eternal question, “what makes us human?” has been paired with the mysteries of the brain for many years now. Neuroscientists, psychologists, and doctors all over the world have tried to locate the origin of consciousness. So it was a giant step forward when a group of researchers at George Washington University found what might be the on-off switch of consciousness. The researchers tested their theory on a woman who suffered from epilepsy. During the test, they delivered a series of high-frequency electrical impulses to the claustrum region of her brain. Before the electrical impulses, the woman was able to write and talk perfectly fine. Then, during the electrical impulses, she faded out of consciousness. She stared blankly into space and didn’t respond to what the scientists told her to do, becoming incapable of even the most basic functions. The moment the electrical impulses stopped, the woman regained consciousness with all her senses intact. She had no memory of the time during the test, feeling just like she had fallen asleep. Now, many researchers believe this part of the brain is the key to our consciousness and it may be the first step on reverse-engineering the brain so eventually, we can reproduce it in AIs. Obviously, these guys haven’t watched Terminator 2!
7 - Did it really happen?
If you like sci-fi or spy movies, this one may sound familiar. In 2014, a team of neuroscientists discovered how to implant false memories. Hold up, people were actually incepted?! Steve Ramirez and Xu Liu were the first scientists ever to prove that you can trick brains into remembering things that actually never happened! In the experiment, they placed a rat in a small metal box with a black plastic floor and let it take a look around. Then, they put the rat in a completely different room and applied an electric current while stimulating the rat’s brain to trigger memories of the box with the black floor. Days later, they placed the rat back in the first box and watched what happened. The rat froze in terror, because it remembered getting shocked there. Except, it hadn’t! The rats were associating the shock with the false memory caused by the stimulation to their brains. The research has ignited a lot of arguments on ethics and identity. Up until now, no memories have been implanted in humans, but is it only a matter of time? What do you guys think? And when it happens, what will it say about our actual memories? Social scientists have claimed for a long time that memory is identity. We are what we have experienced, and what we remember. If we can erase a bad memory, or create a good one, how can we ever know who we are? We’ll find out in the future!
