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 (see image, right). “It is hard for me [to say] exactly the percentage of reduction of the brain, since we did not use software to measure its volume. But visually, it is more than a 50% to 75% reduction,” says Lionel Feuillet, a neurologist at the Mediterranean University in Marseille, France. Feuillet and his colleagues describe the case of this patient in The Lancet. He is a married father of two children, and works as a civil servant. Not retarded The man went to a hospital after he had mild weakness in his left leg. When Feuillet's staff took his medical history, they learned that, as an infant, he had had a shunt inserted into his head to drain away hydrocephalus – water on the brain. The shunt was removed when he was 14. But the researchers decided to check the condition of his brain using computed tomography (CT) scanning technology and another type of scan called magnetic resonance imaging (MRI). They were astonished to see "massive enlargement" of the lateral ventricles – usually tiny chambers that hold the cerebrospinal fluid that cushions the brain. Intelligence tests showed the man had an IQ of 75, below the average score of 100 but not considered mentally retarded or disabled. "The whole brain was reduced – frontal, parietal, temporal and occipital lobes – on both left and right sides. These regions control motion, sensibility, language, vision, audition, and emotional and cognitive functions," Feuillet told New Scientist. Brain adaptation The findings reveal "the brain is very plastic and can adapt to some brain damage occurring in the pre- and postnatal period when treated appropriately," he says. "What I find amazing to this day is how the brain can deal with something which you think should not be compatible with life," comments Max Muenke, a paediatric brain defect specialist at the National Human Genome Research Institute in Bethesda, Maryland, US. "If something happens very slowly over quite some time, maybe over decades, the different parts of the brain take up functions that would normally be done by the part that is pushed to the side," adds Muenke, who was not involved in the case.

I was surprised when I read this news on Ceefax how this guy can lead a normal life with an IQ of just 75 (thought that was called retarded but apparently not in this case) and with next to no brain tissue.
Just wonder who this person is ... -bigsmile 2 educated guesses: - Ronald Reagan - George W Bush -evil
dam the websites not working, so the pic is down (dam hotlinking ) but if you saw the pic, he doesnt have a tiny brain, he almost has no brain at all!!!
