how do (they) (we) determine how many percent of our brain is active ??

Question

you know how they say only 5%-10% of our brain is active ??

i asked how do they determine ...didnt ask how active ur brain is ...

Answer 1

We usually use an EEG which stands for encephalogram and what it does is it measures brain waves and the applitude of these waves can determine how much of our brain is being used. Other devices such as an fMRI or a functional MRI are used to help us see which part of the brain is active during different tasks. For example if you are in an fMRI and we ask you to raise your hand the motor cortex of the brain will become more active because you are doing a task using motor skills,

"...What follows are two of the reasons that the Ten-Percent story is suspect. (For a much more thorough and detailed analysis of the subject, see Barry Beyerstein's chapter in the 1999 book Mind Myths: Exploring Everyday Mysteries of the Mind.)

1) Brain imaging research techniques such as PET scans (positron emission tomography) and fMRI (functional magnetic resonance imaging) clearly show that the vast majority of the brain does not lie fallow. Indeed, although certain minor functions may use only a small part of the brain at one time, any sufficiently complex set of activities or thought patterns will indeed use many parts of the brain. Just as people don't use all of their muscle groups at one time, they also don't use all of their brain at once. For any given activity, such as eating, watching television, making love, or reading, you may use a few specific parts of your brain. Over the course of a whole day, however, just about all of the brain is used at one time or another.

2) The myth presupposes an extreme localization of functions in the brain. If the "used" or "necessary" parts of the brain were scattered all around the organ, that would imply that much of the brain is in fact necessary. But the myth implies that the "used" part of the brain is a discrete area, and the "unused" part is like an appendix or tonsil, taking up space but essentially unnecessary. But if all those parts of the brain are unused, removal or damage to the "unused" part of the brain should be minor or unnoticed. Yet people who have suffered head trauma, a stroke, or other brain injury are frequently severely impaired. Have you ever heard a doctor say, ". . . But luckily when that bullet entered his skull, it only damaged the 90 percent of his brain he didn't use"? Of course not."

Answer 3

not true that only 5-10% is active. we use almost all of it all the time. we just do not put it all together well. we could do better at combining the talents of the brain.

Answer 4

think of pie chart.100% for a complete brain activity but there are many areas called "gray areas" in our brain that does not show heat.so from those other areas you minus from 100%.

i'm 31.... I reported smoking weed whilst i replaced into sixteen.. and it replaced into bliss..i enjoyed the way it made me experience. I stored it to weekends at events. whilst i replaced into 18 i replaced into finished fledged continual..i consistently had to be stoned. I in no way extremely known it as being a issue on the time ( nonetheless now i comprehend it as being a brilliant issue) on condition that i ought to function oftentimes at artwork, employing , being social etc. I then went away for a three hundred and sixty 5 days and replaced into no longer able to locate weed everywhere. So i give up ( no longer by employing decision) after a three hundred and sixty 5 days of no longer something, i ultimately stumbled on some..yet, as quickly as I smoked it, i did no longer get an analogous completely happy feeling. instead i felt insecure, paranoid and extremely very anti social. even nonetheless the end result wasn't pleasing, i persevered for years greater often than not with the aid of fact i replaced into chasing the extreme i used to get. I say smoke sparsely...shop it as a social factor. Be very careful..it messes with your concepts chemistry and could pull you right into a deep melancholy very unquestionably

Universities are always looking for people to test. Contact one of them.

How did you get your name to appear as nothing but a series of rectangles?? That is just too cool. Obviously you are using a higher percentage of your brain than the average Joe.

Answer 7

only 20 % of the brain we can use

Answer 8

they use heat sensors and stick them to our scalp the more heat the more blood thus meaning that more blood is needed for difficult and complex actions.

Answer 9

mine is over 100% as i never stop hehehehe but then i am left handed hehe
