The Unused Brain
The Unused Brain
One myth about the human brain is the claim that humans use only about 10 percent of their brain capacity. Medical doctors and psychologists insist that the statement is not supported by any scientific evidence.
It is likely the myth that humans use only about 10 percent of their brains arose during 1930s research when scientists were uncertain regarding the functions of large areas of the cortex. In recent years, researchers have been able to "map" the functions of different areas of the brain.
The neocortex, by which higher thinking is performed, consists of a sheet of cells about 2.5 millimeters in thickness. Without the neocortex, consciousness, would not exist.
Although the neocortex is a large part of human evolution, it does contain cavities without any brain cells, as well as considerable amounts of cerebrospinal fluid, white matter, blood vessels, blood, and "non-thinking cells." However, scientists say these areas should not be constituted as the mythical unused 90 percent of the brain.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
