What happens when you put three delusional men, all of whom believe that they're Jesus Christ, in the same room? In the late 1950s, a psychologist at a mental hospital in Michigan got the chance to find out.

About a century ago, a scientist had a dream in which he devised an experiment. He forgot the dream the next morning, but it still managed to win him to Noble Prize, and ultimately to save his life.

The working title for this week's episode was "Hitler's Hysteria," which I liked for it's alliteration. The term hysteria is generally frowned upon now. It's a lot less offensive, and a lot more effective, to call these sorts of conditions conversion disorders, or somatization disorders...

The concept of cognitive dissonance has been with us for a long time (Wikipedia points out an example from Aesops Fables), but Festinger was the first to coin the term.

Valproic acid is one of the key ingredients in Depakote, the most widely prescribed antiepileptic (seizure-controlling) drug in the world. I introduced the topic by talking about a recent lawsuit against Abbott Laboratories, the company that makes Depakote, for illegally marketing their product...

Eventually, he invented the EEG, that device that doctors hook up to a patient's head to get a bunch of squiggly lines...
