An image of a neuron
10. While we laugh, about 5 areas lit up in the brain simultaneously. So it's no laughing matter, laughing.
11. The reason tickling makes us laugh is that the brain becomes 'surprised' by this kind of touch, which is first interpreted as a threat. The uncontrollable laughter is actually a panic response by the body. That is why it's not possible to tickle ourselves.
12. The human brain has more 'wrinkles' and crevices than those of other animals. In this way, the brain gets more surface space, while staying at around the same size, and it is part of the reason for our increased intelligence.
13. Brain cells, or neurons, are not only found in the brain, but exist everywhere in the body the brain needs to send orders to, and all of them are connected to the brain.
14. Some archaeological findings think that our cranium has gotten smaller over the ages, but that doesn't mean our brain has become less powerful, only more efficient (see #12). 15. The brain alone uses 20% of all the oxygen we breathe and over 25% of the sugar we consume. Meaning, deep thoughts might cost the body resources just like sports can. Who said chess players are not athletes too?
16. The female and male sexual hormones cause a different brain to develop. Studies have found siginificant difference in the brain functions of male and female during social situations, decision making, pressure situations and more.
17. The brain isn't fully developed until the teen years are over. Multitasking, showing empathy and good decision making are some of the skills that develop a little later. This, we're sure you'll agree - explains A LOT.
18. The brain is constantly changing. Damage to one part of it may cause that part to change to a different location in the brain, especially if you are a baby or a child. Beyond that, every thought, experience or skill we encounter and learn changes the structure of our brain.
19. Memories aren't built in a linear progression. We only remember 'pictures' or moments, and we put together a story from them ourselves. That is why it's tricky to trust your memory, because you may have done some 'editing' without knowing it.
