Yeah I was told by a friend we only used 90% of our brains? Is this true?
Where does the 70% come from?Normally we are using around 70% of our brain ressources but fortunately not at the same time. (temperature problem).
Those scans don't actually tell us much about what parts of the brain are active; instead, they tell us which parts of the brain are MORE active compared to a baseline value. This misunderstanding of how to interpret those scans only contributes to the myth that we use only a small portion of our brains at any given time.eeka chu said:So, when you image someone's brain, you can find that quite a lot of the brain tissue isn't actually doing much.

This is really about memeory retrieval. We are so busy with a million thoughts at once, we often have lose track of, not the memory, but the "tag" that allows us to retrieve the memory easily.citizen said:The brain isn't really my specialty so please forgive me if this question is "dumb"...
If we could potentially use 100% of our brains at any given time then why do we forget things? It would seem where I parked would be well within the brain capacity and yet I have forgotten where I parked before...
