7 Myths About The Brain You Thought Were True


Recommended Posts

Posted
the brain is amazing and complex but a lack of understanding has led to a great
0:04
variety of myths throughout the years
0:06
like bigger is better while this may be true for some
0:09
other organs you only need to look at a sperm whales brain which is nearly six
0:13
times larger than that of humans
0:14
to see this myth fall apart yes there certainly intelligent animals but their
0:18
cognitive skills pale in comparison to our own
0:21
had a fun night out don't worry alcohol doesn't actually kill your brain cells
0:25
although it does cuz damaging creates problems conveying messages between
0:28
neurons
0:29
the damage is mostly reversible similarly drugstore actually create
0:32
holes in your brain
0:34
though some can permanently change your brains functionality and structured
0:37
the only thing that can put a hole in your brain is physical trauma
0:40
good thing you have $100 billion brain cells or not
0:44
surprisingly it wasn't until 2009 that scientists discover the true number to
0:47
be closer to $86 billion
0:49
sure it may seem like a small difference but those fourteen billion neurons are
0:53
equal to the size
0:54
I'm an entire baboon brain to further put those numbers in perspective
0:57
consider that one million seconds is twelve days well one billion seconds is
1:02
31 years
1:03
so that fourteen billion neurons difference may not be so small after all
1:07
regardless we can't use them all right most movies in sci-fi books have us
1:11
believe that humans can only use around 10 percent of our brain
1:14
which is absolute nonsense thanks to modern brain scanning technology
1:18
we know that we use the whole thing all the time not necessarily all at once
1:23
when you're walking for instance the part of the brain associated with
1:25
movement are more active than other areas
1:27
however there's no part of the brain that simply doesn't do anything
1:31
it represents three percent of the body's weight and uses 20 percent a bit
1:35
energy
1:35
that's a busy brain but we generally use one side more than the other right
1:40
nope well you may have been convinced that if you're more logical or
1:43
analytical you're more
1:44
left brained in a few more creative going to give you more right brain
1:48
it's simply not true while different sides of the brain are indeed use for
1:51
specific functions for example
1:53
languages the left hemisphere where the right hemisphere helps to read
1:56
a motion studies on thousands of individuals have found no evidence
2:00
have a left or right dominance in individuals in other words
2:03
you use both sides equally and you don't actually have
2:06
five senses like you were always told in fact you have a lot more
2:10
like no sabes in which is the sense a pain and probably a sub shin
2:13
the sense of how our bodies are positioned not to mention the sense of
2:17
balance temperature and passing of time
2:19
scientists at GE global research centers are collaborating with top researchers
2:23
and institutions to uncover new insights about the brains functionality
2:26
if you're interested in debunking more minutes or understanding more about the
2:29
brain
2:30
you can follow their progress at GE reports as they work together to crack
2:33
the brains greatest mysteries
2:35
