Just for fun: Be the neurosurgeon

Here's your chance to be a virtual brain surgeon. The program designed by Edheads, a nonprofit educational organization, is called Deep Brain Stimulation. In this 'game', you actually get to practice drilling holes in peoples' heads. Warning, this game is quite graphic with pictures of actual brain surgery. For the squeamish, Edheads also presents Design a Cell Phone and other games.

Like all their products, Deep Brain Stimulation is free of teachers, students and parents.
