Isn’t our brain amazing?
Have you ever wondered how it works?
Here’s a list of brain trivia that I found interesting:
1. You have a finite amount of will power each day because to exercise will power you need energy in the form of oxygen and glucose That’s why it’s harder to say ‘no’ when you are tired or not feeling yourself.
2. A thought is a physical pathway in the brain. The more you have that thought the more you groove that path and the easier it is to have it again. That’s why having the thought “Why do I suck?” is never a great idea.
3. Speaking of which, you have approximately 70,000 thoughts per day, although many will be the same ones looping round and round on your grooved cranial highway.
So make sure you don’t think, “Why do I suck?” 50,000 times a day, or suck ye shall.
4. Reading out loud to kids accelerates their brain development.
5. Reframing negative events in a positive light literally rewires your brain and can make you a happier person, as can regular meditation.
6. The brain is approximately 75% water, but you should never drink it.
7. Your brain only weighs about 3lbs yet it uses between 20% and 25% of your energy supplies each day.
8. There are approximately 10 to the power of 60 atoms in the universe. Your brain laughs in the face of that figure however, as it has 10 to the power of 1,000,000 different ways it can wire itself up.
That’s the number 10 followed up with 1 million zeroes, which is to all intents and purposes (for anybody not called Stephen Hawking or Rob Collins), an infinite amount of ways.
9. Speaking of large numbers, there are approximately 1.1 trillion cells and 100 billion neurons in the average human brain.
10. If you lose blood flow to your brain you will last about 10 second before you pass out.
11. Your brain has no pain receptors which is why if I managed to remove the top of your skull without you noticing I could poke around all day without you feeling a thing. The skull removal may hurt a bit though.
12. Leaving aside degenerative brain disease, your brain never loses the ability to learn and change because it’s effectively plastic and constantly rewiring itself.
13. It ‘s a self development urban myth that we only use 10% of our brain. We use it all and if you don’t believe me cut a bit out and see what happens.
14. When somebody takes cocaine their pleasure center (nucleus accumbens) lights up and dopamine and serotonin are released. Fortunately, you don’t have to blow your life savings, act like an idiot and lose your nasal lining to get similar results.
Giving to charity or helping people in need also activates the nucleus accumbens. What a win/win that is, eh?
15. Multi-tasking is a self development urban myth. You simply cannot do it efficiently no matter what manufacturers of smart phones want you to believe.
According to the University of Utah, there are a few people (about 2.5% of the population) who can do two things consciously* at once without seeing any degradation in performance.
They are called super-taskers.
However, for most people all the brain is doing is going backwards and forwards very quickly and giving the illusion of multi-tasking. The reality is performance is inhibited by this approach not improved.
* I do appreciate that you can do multiple things unconsciously at once such as driving and talking. (Not texting though!)
16. Your brain is constantly lying to you when you have your eyes open. Because it cannot deal with every single detail that you’re looking at, the occipital lobe is joining the dots with what it presumes is there.
17. Similarly, your brain doesn’t record memories like video as it would be easy to assume. It takes snapshots of the more important bits and then when you recall the event it guesses what happened in between based on prior experience.
18. Your brain finds it very easy to create false memories largely because of the above and the fact that it spends so much time guessing what’s happening.
When scientists exposed people to Photoshopped images of themselves at various event years prior they were soon able to explain what they were doing and recall the event with clarity even though they were never there.
There will be events you swear blind happened the way you remember, but never actually did. A sobering thought.
19. Your brain is fairly bad at distinguishing between what’s really happening and what you are merely imagining. Which is why horror films scare people and porn films, er…ahem, well you know.
20. The brain is very poor at concentrating for long periods of time and needs to clear it’s head so to speak about every 90 minutes or so.
