The human brain is the most powerful and least understood part of the human body. But do you know, how fragile truly is? Although the skull is very hard, the brain is very soft. 80% of the brain is water. There are no pain receptors in the brain so it can’t feel pain. A headache involves muscles and nerves in your head.
In the video below Suzanne Stensaas, Ph.D., Professor of Neurobiology and Anatomy at the University of Utah School of Medicine, demonstrates the properties and anatomy of an unfixed brain.
