Over the past few years, a host of discoveries have shattered people’s notions of how the human brain works. For example, medical experts have discovered that certain individuals with a severe lack of gray cerebral matter—so-called “brainless guys”—have normal or super-normal intelligence; and that animal brains recovered four hours after death. Therefore, several scientists have introduced the concept of “the invisible brain” to decipher those mysteries.
Besides, the brain’s energy properties are gaining increased attention from the medical world.
