I have heard it from science magazines, newspapers and various people that the average human only use approximately 10% of their brain.
This simply isn't true.
Here's the thing, though; it's not really true. In addition to those 100 billion neurons, the brain is also full of other types of cells that are continually in use.
If the average human brain weighs 3 lbs and 90% of it was removed, that would leave 0,3 lbs of brain tissue. That's about the size of a goats brain. If damage to a small area of the brain, such as that caused by a stroke, may cause major disabilities. Conditions like parkinsons "infect" only specific areas of the brain. The damage caused by these conditions is far less than damage to 10% of the brain.
quote:
How could a human that has evolved be using less than 100% of its brain unless humans have de-evolved some how? Unless the 'random evolution' somehow 'evolved too far' and now humans have ended up with all this wasted brain space? I dont understand.
Even though the 10% statement is false you seem to make the bold assumption evolution as purpose. Can't evolve "too far" if there was no set path. It just has a "whatever works" feel to it. Humans and all living things have whats called "junk" DNA and organs that simply have no use... It just is. They may have once had a use or in the case of most DNA just mutation.
