Here are some mind-bloggling and stunning facts about our brain.
1. The Brain Doesn’t Feel Pain
Why does our brain doesn’t feel pain?
Reason: Because there are no pain receptors in the brain. That’s why surgeons can perform brain surgery on a patient why they are still awake. This helps them ensure that the delicate procedure doesn’t screw up any vision or motor control functions – and also it looks really freaky. Why do we feel pain? Because a nociceptor, a sensory receptor, sends signals to the spinal cord and brain alerting us to danger.
2. There Are Differences Between the Right and Left Brain
The brain is split up into two symmetrical hemispheres. While they do work together, the left brain favors more rational, analytical thinking, while the right is more visually and conceptually oriented. They also work in opposites – you stub your left toe and the “pain” is processed on the right side. And they put right-side-up whatever is upside-down – the image in your eyes is actually received inverted and the brain corrects it. But here’s the REALLY weird thing – even if you were to lose one-half of your brain, you would be able to survive without it.
3. Men’s Brains are 10% Bigger than Women’s
So there you go – concrete proof that men are smarter than women. But before you go patting yourselves on the back, dudes, note that although women’s brains are smaller, they have more nerve cells and connectors and work more efficiently than men’s. And, true to the stereotype, they tend to process on the more “emotional” left side of the brain, while men process on the “logical” right. Also, an area known as the straight gyrus, responsible for nurturing, feminine traits, is proportionately larger in women.
4. Why Do We Laugh? We Don’t know!
True laughter is involuntary – that’s why the milk comes gushing out your nose. Only human beings are born with this ability (a Laughing Hyena is not really laughing) and babies begin giggling at 4 months old. And while true laughter is contagious, it is also something not easily faked. But WHY do we laugh – it’s not because of jokes. Over a 10-year period, one doctor studied 2,000 laugh-inducing situations and discovered that most of the time a guffaw was not the result of a punch line. Maybe someday we will understand why we are ticklish, too.
5. Does Size Matter?
Research has been mixed on the subject of brain size and intelligence – Albert Einstein’s brain was only 1,230 grams, while the average adult male brain weighs 1,400. (An unusually large amount of glial cells are attributed to his smarts.) Another study shows that the bigger the person’s head, the smarter they are, while those with pointier heads show less intelligence. That can’t be true.
6. Your Brain is More Active When You Sleep
Night-time is the right time for your brain to process all the activity that has occurred during the day – that’s why scientists think we dream (no one is really sure why). Some believe it’s a way to process the complex emotions and interactions of our daily lives, others think it’s just a way to zero-out information, much like a computer. A recent study showed it may help us alleviate trauma. People with higher IQs tend to dream more, and a nap during the day has proven to make people more energized and focused on their work. Tell that to your boss.
7. Highest IQ? Kim Ung-Yong with 210
Born March 8, 1972, Kim Ung-Yong already understood algebra at 8 months old. By the time he was 2, he was fluent in 4 languages. He began attending university at 4, and graduated at 15. But Ung-young isn’t just a smarty-pants, he is also a gifted painter and poet.
