" Two University of Texas computer scientists programmed a voice-recognizing computer with neural networks and taught this artificial brain simple stories. They then simulated a hyped-up dopaminergic system by reducing its ability to forget or ignore. This unfortunate computer became delusional. It made up wild, disconnected stories, even claiming credit for a terrorist bombing. If computers can go crazy, can they be cured? If computers can be cured, can we be cured?"

I would like to know how they drove the computer "crazy" (and how this maps to human neurology, if at all).
