12 Amazing & Shocking Facts about the Human Brain
Hey everyone and welcome to top amazing think today we are going to learn about 12 shocking facts about the human brain. Now let's begin. |

Number 1 - Intellectual peaks, your brain stops growing when you're 25. But
that doesn't mean you've reached your intellectual peak. Cognitive change is a
lifelong process some skills like memory and processing speed max out in your
mid-20s. You'll excel at facial recognition and problem solving in your 30s and
then gain emotional control and empathy in your 40s and 50s. A select few
skills like vocabulary take even longer, peaking in your 60s and 70s. Now your
brain may have matured but your mind has plenty of room to grow. That's why you
should never stop learning no matter how old you get.
Number 2 - Audible sites Have you ever heard that missing one of your senses
amplifies the others going blind or losing your hearing won't make you a
superhero, but it can give you a few different neurological advantages. A 2011
study found that people who were born blind sometimes develop a new way to
process the world around them. They essentially begin seeing through their
ears. The human brain excels at adapting to difficult situations. This kind of
reorganization is called neuro plasticity. So when someone can't see the brain
automatically searches for an innovative solution. It will often rewire itself
to process auditory information over visual information. It isn't quite the
same as normal vision, but this workaround can yield some pretty amazing
results.
Number 3 - Hogging blood. The average person's brain weighs about three
pounds. Now For someone who weighs 150 pounds total, that's only 2% of their
body weights. That's barely anything when you think about how important the
brain is to your body, but without its you couldn't do anything you couldn't
think you couldn't speak. No, you couldn't even move. So how does such a small
Oregon manage so many executive functions, the real difference between the
brain and the rest of the body isn't in its size. It's the amount of oxygen and
blood that your brain needs to work like it's supposed to. So even though it's
only 2% of your weight, it requires about 20% of your body's supply of oxygen.
That's more than all of your other skeletal muscles combined. So if you've ever
wondered how blood is distributed inside your body, now you know the brain is
taking a significant chunk. Yeah, it's a blood hog.
Number 4 - Miles of blood vessels since needs so much blood and intricate
network of vessels is working around the clock to bring oxygen to every part of
the brain. Because if one section isn't getting enough blood, you start losing
basic functions. Some people experience blindness or fatigue, others lose all
feeling and one or more parts of their body almost like they're paralyzed. So
how many blood vessels does it take to keep your brain up and running? Well, to
know for sure, you'd have to untangle a web of veins, arteries and capillaries,
you'd see that the average person has hundreds of miles of blood vessels inside
their head. Yeah, I know that doesn't seem possible doesn't. Your blood vessels
are just so thin and tightly woven together that they fit inside a much smaller
space. Now researchers are still working on counting the number of blood
vessels in your brain. We do however, know that the entire body measures up to
100,000 miles that’s like driving around the widest part of the earth four
times. And those are the blood vessels of just one average sized person.
Imagine how much distance the entire human race could cover.
Number 5 - Brain starvation. So what happens when your brain doesn't get any
oxygen at all? How long can it last before something goes wrong? The answer is
not very long. After five to six minutes without oxygen, you're risking
significant brain damage. That's because your brain can't actually store any
oxygen on its own. It relies on the body to send a constant supply all day
every day. And if that stops happening, your brain only has a few minutes left
to live.
Number 6 - Neural Speedway. Every action in the brain starts with an
electrical signal. Some are sluggish and slow. Others race across the Brain
clocking in at over 230 miles per hour. Wow. The speed of a signal depends
primarily on what kind of signal it is. When you touch a hot surface for
example, that sensation speeds through your body. It starts at the sensory
receptors on your hand, passes through your spinal cord, and then enters your cerebral
cortex. There you perceive and process how hot the surface is, which sends a
new electrical signal rushing through your brain and your body. So if you've
ever wondered why it takes a second to realize how hot something is, you found
your answer.
Numbers 7 - Thousands of thoughts. You spend the majority of the day thinking
you wonder if anyone has noticed the stain on your shirt. You think about
whether or not you locked your car. So many random thoughts pop into your head
all day long. But has anyone ever tried to count them? Researchers go back and
forth on the exact number but most agree the average person has about 50,000
thoughts every single day. That's at least 2100 thoughts per hour. Most are
small and repetitive, but it just goes to show your brain never stops working.
Number 8 - Shrinking brains. Who do you think has a larger brain, modern
humans, or our early ancestors? This discovery surprised researchers around the
world. It turns out, our 10,000 year old ancestors had larger brains than we do
about 10% larger to be exact, but it's not because they were necessarily
smarter than us. Several neuroscientists have explained this change in brain
size. Our brains are getting smaller because our bodies are too. So that means
we have a smaller nervous system so we can afford to carry a lighter, more
efficient brain than our ancestors. There are plenty of times when smaller
brains outperform larger ones. Instant computations are a great example. We may
not have as much room to store information, but our processing speed is through
the roof. When you think about it, our brains have gotten smaller to adapt to
our modern lives. If we really needed bigger brains, well, we'd still have
them.
Number 9 - The fattiest organ, your brain is actually the fattiest organ in
your entire body, right fat head. Think about the construction of the human
brain. Are you picturing the hundreds of millions of neurons, the complicated
network of blood vessels, that dozens of glands secreting all kinds of
hormones, but did you know that 60% of your brain is just plain old fat?
Despite being one of the largest organs in the body, the brain doesn't have any
muscle? It controls muscles and a whole lot of them but it's made of fatty
tissue. Here's the problem. Your body makes a lot of different things, but fat
isn't one of them. So all the fat your brain uses for performance and repair
has to come from the food you eat. This is why so many dietitians push people
to consume large amounts of omega three fatty acids. Now those important fats
facilitate brain development, stave off disease, and preserve your mental
health. So do your brain a favor and work a little more efficiently or die.
Number 10 - Synchronized brains. Countless studies have shown the
extraordinary ways that music interacts with a human brain. It evokes emotions
recalls memories improves creativity and problem solving. But a German study
discovered that music could actually synchronize brain functions. To test this
out, they scan the brains of two musicians while they played music together.
And sure enough, the music slowly but surely synchronized their brainwaves?
It's very possible that the best bands sounds so good together because their
brains are working in tandem.
Number 11 - First brain surgeries. If you had to guess when would you say the
first brain surgery was ever conducted? The surgical world made its first real
bit of progress in the late 18th century. Do you think the first brain surgery
happened somewhere around then right? After all, brain surgery is one of the
most complicated and volatile kinds of surgery there is. Just one little slip
up could completely ruin your patient's life. A tiny cut could steal away their
speech or change their entire personality. Well, surprisingly, the first brain
surgery happened during the Stone Age. Yeah, over 5000 years ago, early humans
were doing something called trepanation. It's when you remove a bone from
someone's skull, archaeologists already found dozens of examples of this
ancient surgical technique. Chances are it wasn't all that safe or effective.
But these people were still performing surgery before things like math or
written language ever existed.
Number 12 - Five year olds brain, the brain develops in a pretty strange way.
When you're born, it's about one quarter of the size of an adult brain. That's
pretty big considering how small an infant actually is. But as we all know,
there's a lot of things that baby can't quite get their heads around. That's
because their quarter size brain is primarily focused on keeping them alive. It
handles automatic processes like making your heartbeat and helping your lungs
breathe. Now, you'd expect your brain to keep growing at a steady pace, right?
That way, by the time you get to turn say 25 it would be full grown, but that
isn't how your brain works. It actually doubles in size. Eyes during the first
year of life, and by three years old, your brain is almost 80% of an adult
brain. That number jumps up to 90% by the age of five. During those crucial
years, your brain is forming millions of new synapses every single second. It's
learning everything from symbol recognition to behavioral habits, which are
important functions that you'll need later in life. So the next time you're talking
to a five year old, try to remember that their brain is almost as big as yours.
