1. The
belief that humans only use 10% of their brains is incorrect. Each part of the
brain has a specific function and the average person uses all the various parts
of the brain.
2. Have
you ever had such a headache it felt like your brain is going to explode? That's
not actually your brain hurting, because the brain has no pain receptors at all.
Mother nature assumes you don't need it because it's never exposed (thankfully)
and is usually protected by our thick skull.
3.You must
think that your buttocks are the fattiest part of the body, but it is in fact
the brain with the most fat % in the body, about 60% of it is
fat.
4. The
brain has a texture similar to tofu, and enough liquid to fill a 2 liter (half a
gallon) tank.
5. Thought
creates 'pathways' that connect different parts of the brain. The more we repeat
a thought, the more that pathway will become more central, wide and stable. That
is why it is important not to think over and over about negative things, because
they become permanent, and strong, pathways in your mind, and the chances are
will force themselves on you more and more.
6. We
think about 70,000 thoughts a day. A large part of these are 'automatic'
thoughts that we repeat a lot, using our most 'established' thought
pathways.
7. Most
people dream about 4-7 dreams a night. 50% of those dreams are forgotten in the
first minutes after waking. And the one we remember is usually one we were
either just dreaming or a mix of all the dreams we had put together. No wonder
they always seem so confusing.
8. Sleep
is usually the time the brain uses to organize and put together the memories is
accumulated throughout the day. And so, in many cases, before making big
decisions it's better to 'sleep on it'.
9. The messages between the various brain cells (neurons)
are passed in the form of weak electrical pulses. The brain creates 23 watt of
electricity while awake, enough to light a lightbulb.

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.
