Thread: How many % of our brain do we use??

1. I dunno if i posted this in the correct section...
Jus wanna ask the ques how many % of our brain does an average person use at any given time??

there probably is no real answer to your question, but i think i know why you ask.

we probably use 5% of the capacity the brain could offer but generally most people use all parts of it at some time. at any one time, there is no answer.

in school we were told Einstein used 5% of his brain and he was thought to be extra smart. i am not suggesting were all Einsteins, but our capacity may have increased and his was directional, many things he didn't understand or was ignorant of but certainly excelled in others. the brain also controls all functions of the human body, so even the seemingly least intelligent person, if totally functional uses a fair percentage.

Well, that depends on what you mean by Brain Capacity. The human brain is capable of a larger amount of things than most people currently use it for. An old myth is that we only use 10% of our brains at any point in time. This, however, is proven seriously false (thanks to neurology as well).

Yet, on the premesis that we only use a certain CAPACITY of the brain, you have to take into account numerous factors. Some people would be born with a higher "capacity" than others, and you also have to define what "capacity" is. The amount of electrical activity before the brain begins it melt might be considered one capacity.

5. Erm, thx. But, what i was asking was actually how many % or ur brain max do u use at any given moment. For example when u think very hard with all ur might....

6. I don't really believe that's been classed as a "percentage" since there is absolutely no defined limit...so I doubt you'll get a link on it.

7. i will stick to my answers; the question is posed as a comparison to no usage what so even.

brain activity can be measured and we have a good idea what each section of each lobe controls. activity will increase or decrease but
usage as i think the question is asked, is not determinable. an athlete for instance may require more brain activity than a scientist explaining a complex formula. if the athlete was also a scientist, tried to explain a complex formula while pitching a baseball would probably peak out and one or both objectives would suffer. the % used at peak out, disputable.

i have heard the 10% figure as well, in school it was 5%. if i have a point it would be the brain functions in many ways not considered in the debate and intelligence is not a major factor. the first thing taught in law school, is not to memorize more than you need to, but to know where to find answers.

8. If we only used a few % of our brain then Kennedy would have been sent home with a packet of headache powders.

We use 100% of it.

9. Like i keep repeating ..... the question i was asking was about how many % of our brain does one use at "ANY GIVEN MOMENT" not during his life time......... y do iget reply of we will eventually use all parts of the brain... that wasn't my ques..... pls read be4 answering..... thx

plz us pupr gamur, thx.

11. Perhaps refining your question toward how much perchentage of the brain is used in concious thought at once compared to brain cells which might either lay dormant awaiting activation, or do subconcious things like controll breathing and such.

the peak out example used above is a very good example. when you try multi-tasking you can note a decline in one of the things your doing. lets say your running on a tread mill at a good speed, reading a monitor with math problems and writing poems on a type writer and giving a speech on thermal dynamics to a group asking questions. no one can do this with anything close to half efficiency. now if you or anyone could do all this and a few more things simultaneously, you could get to 25 or 50 % of the figure your looking for. there could always be something you could add to the tasks, until you reach 100%. most of us have trouble doing two things, much less ten things at the same time. thus the 5 or 10% figures are used.

the question goes to depth and this is what could be improved on. it was explained to me; the brain has a theoretical number, of events it can remember and if that point was reached, you would have to forget something to add another. this figure for events remembered however is about 5-10% of what should be a total.

involuntary brain actions or impulse, eye sight, breathing, heart actions, hearing, pain, taste and senses MAY, be improved on. they also can be limited and some are lost or never develop.

all this is really very complicated and the actual, provable, scientific answer to your question is not available.

mega; very few people use 100% of their brain. some parts are thought not to develop. some more or less than others. sight (color)-hearing-pain-smell, are a few most common. i go to this since it plays a big role in much of what i think on so many subjects and why when 100k people see an event, you have 100k explanations of that event.

13. ya...many blah blah blah, questions...

How you know how many %? Using ruler? Electric pulse detector? Break their forehead while they're thinknig?

14. i think u can measure it using an MRI to measure the brain activity. the part which is active during activity and calculate the area of brain which is active during any 1 moment.

This is a decidedly sexist comment. :?
Most women have little or no difficulty in multi tasking.

Dark Past, you might try googling for voxels and ROI. If you sift through the resultant flood of data you may find some information. 8) Let us know if you do.

Multi-tasking with effectiveness is an obvious myth. http://www.msnbc.msn.com/id/15225042/

plus, it's common sense that if you do many things at once your brainpower will be spread thinner. there is no such thing as "good at multi-tasking".

not aware i said i was not sexist; having been with ladies in labor however, i suggest they are incapable of any other task at or during child birth. pain, would seem to override most other brain functions. this the point of of lost attention to one task when other task is attempted and the relation to limited brain capacity.

agree there is a lot of information. my opinion is based on some of that material as is my final comment to answer the original question; there is no possible provable answer.

18. people use 100% of their brain, just not at the same time.

easy like that, we allow our brains to rest. we can activate other parts by wanting to activate them, but others will deactivate when we do that. we can't concentrate for more than 20 mins because of that reason. After the 20 mins we'll do fun things, of get agressive or get artistic.. we can't use our brain for to long for the same thing..

19. we do not use 100% of our brains. what we do use is limited to the depths of usage and you are correct use of part of the brain will lessen or cut off use of another.

its thought a good share of the lobe opposite your natural hand, arm, leg usage controls most of your body and mental functions. left handed use the right lobe, right handed the left lobe. the parts of the other lobe are
rarely used. some parts we have no idea what are used for and some are never activated w/o a body function to use.

the use of a part of the brain with extreme concentration (pain-anger) will diminish the use of another. lately this has gone even to parts of the brain we have no control over. during extreme anger, its now thought your heart will give out 17 times more often than if no anger were present.

i will suggest brain dementia in any form, allows people to live longer than they might have. the only brain activity being body functions and these functions fail slower or last and called cause of death, though also caused extension. quality of life, not considered.

as to autistic. we cannot put the brain into that state. this goes to part or parts of the brain that are overactive, maybe even involuntary and in a constant over riding or inactivation of other parts. the degree has been dropped to near normal functions but i question medical motivations and suggest there are far fewer autistics than diagnosed.

i am not even going to 20 minutes and fun things...

There was a study that was done about short-term memory (i forgot what it was called). The study tests how much an average person can do/think things at each moment. The result was 7. An example is an average person can juggle 7 balls to the max. Meaning that you can only do about 7 things in a time.

We cannot use percentage in this unless u want to calculate how much can you do compared to the average number. Say you can do 5 things each time, so 5/7 is 71% of the normal.
