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
