    A normal human uses less than 2% of the brain capacity..

    maybe if you’re brain dead – the normal human brain uses all of their brain, just not consciously. you really think controlling your entire body only uses 2% of your brain’s power? that breathing, keeping your heart beating, seeing, using all your different senses (not just the usual 5, but spatial awareness and stuff too), your conscious thinking, and all your hormone regulation still leaves 98% of your brain power to go to waste? i bet you believe in auras and homeopathy too.

    There are people who have suffered massive brain compression as a result of cranial fluid taking up 80% of the space in their heads and continuing to function as ‘normal’. Science readily accepts that we use only a very small portion of our brain.

    Did you know that hearts have their own brain cell cluster so it functions independently of the brain in our heads (animals too)? Hence a body ‘bleeds out’ when beheaded etc – the heart continues pumping until the body is dry in the case of instant ‘brain’ or ‘head’ death.

    Did you know that the average human has strings and clusters of brain cells equivalent to the size of a cats brain woven into and throughout their belly (specifically the intestines) which controls the whole digestive process?

    Thanks, that’s what i always thought too!

    I just read yesterday: The hands give work to about 50% of the brains surface, because of the mass of nerves, muscles and possible movements which have to be co-ordinated…

    I agree with Vinit. He is speaking about brain CAPACITY not brain power.

    This apparantly is perfectly true, Although 2% Does sound ridiculiously low!!…

    If you removed the brain from the average person and weighed it, . . . That person would most likely die.

    When we are born, over 80% of our brain is composed of fat.

    This is an old story, someone talks about using 2% some other 10%… but the truth is that we use 100% of our brain just very often we don’t use it in the right way 🙂 Medicine has mapped almost all the brain and this was done in many ways but a simple proof is when someone has abrain stroke even though a thin part is damaged there are some loss in function. There are a lot of probable causes of this misunderstanding, perhaps one is that neurons in the brain represent only a minimal part of it (most is glia, support cells) or perhaps that making exercises you can improve your brain ability a lot…

    FACT#11: Brain has ability to make a Colon Copy of Brain:
    Mirror Neurons in the brain has capability to create a phantom body (colon copy of brain) in the invisible World (Same as we store our data in the ‘clouds’ Internet). That phantom brain (colon copy) has capability to reproduce a new brain again (same as a seed hiding under the Earth can develop tree, and tree can produce a seed again.

    Hmmmmm…. thanks 4 the info guys. Everyone’s theory is helping me out a lot. Is that IQ fact true?

    We do not only use a small portion of our brain.

    The brain doesn’t record everything we sense.

    Both of these are common myths. The truth is more complicated and interesting.

    The Smithsonian article “Top 10 Myths about the Brain” covers these.

    Both the “2% of our brain” and “brain stores everything” notions have been soundly debunked. This Snopes article discusses the research on brain usage:


    The classic “Gorilla Suit” experiment shows that we don’t even see everything in front of our eyes:


    Other “facts” might be true, but there are no references, so can we believe them?
