People with strange brains

The strange range of human behavior continues to draw us like moths to a flame. Consider Amanda Fielding who continually performed self-surgery on her braincase, Catharina Geisslerin, the woman who vomited frogs, and the Collyer brothers, who collected so much junk that it crushed them in their own home. Samuel Johnson, compiler of the first dictionary of the English language, was compelled to whirl, twist, and make highly ritualized hand motions when going through doors. Recent research suggests that obsessive-compulsive child behaviors can be caused by strep infection.
