Look inside the brains of mice on drugs!
This is a cute animation from the University of Utah Genetic Science Learning Center. It shows mice on various recreational drugs--heroin, ecstasy, marijuana, methamphetamine, alcohol, cocaine, and LSD.
I think the mouse on ecstasy is supposed to be dancing. The mouse on cocaine looks pretty nervous.
You can pick up each doped-out mouse and "look into its brain." The descriptions of the effects of the drugs on neurotransmitters and receptors in the brain are very well done.
Who says neuropharmacology can't be fun?
