Strange But True: When Half a Brain Is Better than a Whole One (Scientific American)
"The operation known as hemispherectomy-where half the brain is removed-sounds too radical to ever consider, much less perform. In the last century, however, surgeons have performed it hundreds of times for disorders uncontrollable in any other way. Unbelievably, the surgery has no apparent effect on personality or memory."
Man with Tiny Brain Shocks Doctors (New Scientist)
"A man with an unusually tiny brain manages to live an entirely normal life despite his condition, which was caused by a fluid build-up in his skull. Scans of the 44-year-old man's brain showed that a huge fluid-filled chamber called a ventricle took up most of the room in his skull, leaving little more than a thin sheet of actual brain tissue."
Phineas Gage: Neuroscience's Most Famous Patient (Smithsonian Magazine)
"In 1848, Gage, 25, was the foreman of a crew cutting a railroad bed in Cavendish, Vermont. On September 13, as he was using a tamping iron to pack explosive powder into a hole, the powder detonated. The tamping iron-43 inches long, 1.25 inches in diameter and weighing 13.25 pounds-shot skyward, penetrated Gage's left cheek, ripped into his brain and exited through his skull, landing several dozen feet away."
