No it is not. See the link below for more information.
It's an expression, not science. Although, we all know one or two people for whom this is true.
No, it's been proven that when a person isn't doing anything, the brain is actually using at least 30 percent of their brain
Humans can use 100% of their brain. The popular myth that humans only use 10% of their brain is not true. Different regions of the brain are active at different times and perform various functions, but all parts of the brain are utilized to some degree.
true
No. That's completely false. We take advantage of 100% of our brain with both conscious and subconscious activities.
There is a wide-spread myth that humans only use 10% of their brain. While no hard percentage has been published, studies of the brain and imaging technology reveal that almost all of the human brain is being used at any given time.
That is not true, myth that Humans only use 10% of their brain is just a myth.
true
Nope! Humans use their whole brains for a wide variety of functions. It’s unclear where this myth started, but it’s been proven false by numerous brain scans showing that the brain is in near-constant complete use.It is true, however, that only 10 percent of the cells in the brain are neurons; the other 90 percent are support cells called glial cells, but it’s not entirely clear what those are for. It’s also true that there are particular moments where you might only be using 10 percent of your brain, like if you’re sitting still and just daydreaming. But the idea that there’s 90 percent more intelligence tucked away in your grey matter somewhere, and if you could unlock it somehow you’d be the next Einstein—that’s a total myth.
No. If this were true humans would've died out long ago.
You always use 100% of your mind (brain). There is an old wives' tale that says we only use 10% but that isn't true.
