7 Amazing Facts About Your Brain You Must Know
Your brain is the most amazing organ that you own. But do you really know everything about it? Well, nobody knows. In fact, we know more about the universe that surrounds us than this little universe inside our skull.
Get ready to have your mind blown. Here are the top 7 mind-boggling facts about your brain you probably didn't know.
7. YOUR BRAIN FEELS NO PAIN
As much as I hate to say this, but the pain is an important part of our life. Pain is our brain's way of warning us that something is wrong with our body. The organs of our body contain pain receptors. That is why we feel pain.
But, our brain has no pain receptor in it, so it is unable to detect pain in it. That is why surgeons can conduct brain operations even when the patient is awake.
"Hey, then why do I experience headaches?"
That's because of some sensitive structure around our brain like dura and pia does have pain receptors; sometimes chemical released from the blood vessels near dura and pia activates the pain receptors. Which is why we feel a headache.
6. YOUR BRAIN CONSISTENTLY FORM NEW CELLS
For our whole life, we've been told that we born with a fixed amount of neurons. And the number of our brain-cells remain constant only to deteriorate in the later stages of our life.
Well, now we know that's not the case. New research discovered that our brain forms new cells even in our adulthood. There is a place in our brain called hippocampus, that is responsible for generating new brain cells. Scientists have found that new brain cells are constantly generating, even in our adulthood. Our brain never stops changing.
5. OUR BRAIN IS ACTUALLY SMALLER THAN BEFORE
Throughout the history of human evolution, our brain has gotten bigger with time. Right?
Well, not so early. Paleontological evidence shows that our ancestors Homo neanderthalensis had a bigger brain size which was 1600 cm3 . Where our brain's size ranges from 1200 to 1450 cm3(in males). Which almost is a 9% decrease than our ancestors in the last 30000 years.
Is it spooky? Not really.
Christopher Stringer, a paleoanthropologist at the Natural History Museum in London suggested that shrinking of our brain may be related to our shrinking body size. According to him, a larger body size needed a larger nervous system, therefore a larger brain. But our body shrank after the end of the ice age, and our brain also shrank at the same proportion.
4. YOU'RE A DIFFERENT PERSON AFTER A NAP
William Shakespeare quoted this in his play, Macbeth, "Sleep that knits up the ravell'd sleave of care, the death of each day's life, sore labor's bath, balm of hurt's mind, great nature's second course, chief nourisher in life's feast."
It's like this great playwright already knew more about the brain and sleep than we know. Research suggests that our brain constantly changes while we sleep. New neural connections are created inside our brain while the old connections wipe out. It's like our brain relentlessly rewire itself while we sleep.
That means when we wake up our brain is no longer the same as the brain we had before we slept. Quite amazing? Don't you think?
Do you think brain-boosting drugs actually work in boosting cognitive abilities and make you more smart?
3. YOUR BRAIN IS A FATTY GUY
That's right. Your brain is the fattiest organ of your entire body. At least 60% of your brain is fat. It is important to regularly eat healthy fats, such as omega-3 and omega-6, as a part of your diet.
Fueling your brain with fat encourages ketosis which provides energy to the brain and keeps the brain diseases away. Which in turn plays an important role in learning and memory.
Turns out fat is really good for your brain and you.
2. YOUR BRAIN CAN EAT ITSELF
If you ever had the thought that your brain is actively trying to stop you from dieting, you might be just right.
US researchers report that tests on mice uncover that hunger triggers a process called autophagy, as published in a paper by the journal Cell Metabolism. Autophagy is a process that cells use to destroy the parts it no longer needs.
In the study, scientists found that starving the mice caused the AgRP neurons to consume the fats within their own structure. That autophagy then sets off a series of steps, which included releasing fatty acids that resulted in the release of hunger signals, telling the brain that more food was needed.
Next time, when you feel hungry, take that seriously. Otherwise, your brain may start to eat itself. (Brain loves fat, remember?)
1. YOU CANNOT MULTITASK
Let's face it. You might think that you're a great multitasker, but you're not. There is no such thing as multitasking. It's just a myth that badly effects your brain and wasting your time.
When we think that we are multitasking, what we really do is just juggling two tasks simultaneously. Switching from one task to another over and over. Constantly starting and stopping each task repeatedly.
A Stanford University study showed that those who consider themselves to be great multitasker made more mistakes, remember fewer details, and took longer to finish the task than people who do not multitask.
So when you're thinking that multitasking is helping you to improve your productivity, it's actually killing it.
So there it is. 7 facts about your brain.
