Get your learn on. 180+ ways of investigating the human brain = hours of fun for the whole family.
Thanks to an innocuous question by a 5 year old, my entire evening is now being spent investigating and discussing the structure and workings of the human brain. This flash site lets you explore the workings of the brain according to 12 subject areas (each with subtopics which are not included in the "180" count), within each of which are 5 levels of organization from social to molecular, within each of which are three levels of explanation (beginner, intermediate, and advanced.) discovered via Wikipedia.

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.
, compiler of the first dictionary of the English language, was compelled to whirl, twist, and make highly ritualized hand motions when going through doors. When he went for a walk, he touched every post he passed. If he missed one, he went back to touch it.
Recent research suggests that obsessive-compulsive
child behaviors can be caused by strep infection.
