The claim about humans using only 10% of their brain capacity has long been debunked. In fact, most parts of our brains are active almost all the time. It has been confirmed thanks to neuroimaging technologies, including positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), which make it possible to monitor the activity of the living brain.

However, does it mean that we cannot make more of our brains? Science doesn’t give a solid answer to this question simply because it still has a very poor understanding of how the human brain works and what it is actually capable of. The only certain thing is that brain is a very flexible organ, whose structure and organization can be influenced by external factors and altered through a number of activities.
