You use only 10% of your brain
This one is a favourite for many motivational speakers and writers. People who are highly intelligent and those who claim to have psychic abilities are often thought to be able to access and utilise more of their brain than most of us. This myth is often attributed to Albert Einstein, who supposedly used it to explain his intellect. However, PET (Positron Emission Tomography) scans and fMRIs (functional Magnetic Resonance Imaging) have shown that the entire human brain is constantly active...even when sleeping. Although all the brains regions can’t fire concurrently at any given time, just like our muscles, most of the brains regions are continually active throughout a normal 24-hour period.
