Evolution of the Human Brain and the Myth of its Ten-Percent Use

The human brain is a complex organ that controls nearly every function of the human body. As science believes, humans evolved from apes but over time, humans achieved domain specification and maturation in the nervous system due to which they gained sensory, language, and other social cognition functions, called higher-level cognitive functions. Neurogenesis, or brain development, is an organized process that starts from the early weeks of pregnancy to early childhood. During development, brain parts connect to each other directly and indirectly to process information. As the brain is a mysterious organ so many theories and myths are linked to its development and its use. A widespread misconception, a claim, is that most people use only about 10 % of their potential brain power. But there is no room for this myth because we have now mapped almost every region of the brain. Furthermore, PET scans and fMRI clearly show that almost all parts of the brain are connected to each other and all parts are functionally active. And if the parts of the brain are unnecessary and unused, then they must be removed or disappear, according to the rule of the theory of evolution. Now it is the time to put the myth to rest even though it has survived for a whole century
