How many percent of your brain you think you've used so far?

Question

It is said that we only use a small portion like 10 to 20%....you think you've used more than that?

Answer 1

i don't know but i would've like to be able to use the whole 100% of it
i wonder how u can do that

Answer 2

Actually, you've used most all your brain, irrespective of your age. The 20% number that is often touted is a misinterpretation. It resulted from an off-hand comment of a respected researcher that only 20 percent of the brain is used actively, while the other 80 percent is infrastructure supporting that 20 percent. So the whole of the brain is in fact available all the time. The degree of activity in the brain does vary based on a variety of factors.

Answer 3

I use 100% and so do you. You use 100% of your brain all the time. You may be consciously aware of only 10% of your brain activity, but the other 90% is always working. Think of all the activity your brain has to mediate....sensation, perception, thoughts, movement, your circulatory system, your circadian rhythm....and that's just the tip of the iceberg.
Almost every nerve cell in our brains is active most of the time. Scientists can detect this activity by measuring the electrical currents of nerve cells near the surface of the brain. More complex tests like PET (Positron Emission Tomography) can detect oxygen consumption, blood flow or glucose consumption (the sugar that is the brain fuel) by active neurons in all areas of the brain, not just the surface. Just about ALL of the human brain is busy all the time—even when we're sound asleep.

Answer 4

This is a total myth, we use most, if not all of our brain. We might use around 10-20% at a time, but we use all of it in any given day.
