"And yet the man was a married father of two and a civil servant with an IQ of 75, below-average in his intelligence but not mentally disabled." 75 is pretty far below average - one in 20 of the population - and the fluid had been building up slowly over a 30 year period. I'm wondering what he was like to speak to just before seeking medical attention (and what happened next)... I take the general point about being able to function normally in society given such horrendous damage.

What about this case: http://www.drjudithorloff.com/Free-Articles/Is-Your-Brain-Necessary.htm http://www.drjudithorloff.com/Free-Articles/Is-Your-Brain-Ne... >He cites the case of a student at Sheffield University, who has an IQ of 126 and won first-class honors in mathematics. Yet, this boy has virtually no brain; his cortex measures only a millimeter or so thick compared to the normal 4.5 centimeters. EDIT: Here's the paper itself, Is Your Brain Really Necessary?: http://www.rifters.com/real/articles/Science_No-Brain.pdf http://www.rifters.com/real/articles/Science_No-Brain.pdf >Lorber divides the subjects into four categories: those with minimally enlarged ventricles; those whose ventricles fill 50 to 70 percent of the cranium; those in which the ventricles fill between 70 and 90 percent of the intracranial space; and the most severe group, in which ventricle expansion fills 95 percent of the cranium. Many of the individuals in this last group, which forms just less than 10 percent of the total sample, are severely disabled, but half of them have IQ's greater than 100. This group provides some of the most dramatic examples of apparently normal function against all odds.

  Well, yes, that student is pretty amazing. Must be a way of measuring the connection density as implicitly suggested by another poster - neural network perhaps squashed together but structure preserved?

He was still smarter and more versatile than most chimps, dogs, or any artificial "intelligence" built so far.
