Fascinating Information about the Human Brain
The human brain is the single
most complex thing in the known universe. Even in this time of medical
wonders, we still have not been able to uncover the full secrets of this
incredible organ. However, we do know some things about the most
important organ in the body, and here are some interesting ones you
should definitely know about:
|
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.
