I didn't go to university <a href=" http://paulwf.co.uk/facebook/photopopup/ ">ventolin hfa discount card</a> Mice were put into a box with two chambers.  They had different scents and textures, allowing the researchers to determine which chamber they preferred.  After a preference had been determined, the researchers administered cocaine and placed the mice in the non-preferred chamber.  This altered their future preferences when they were once again allowed to select between chambers.  Mice overwhelmingly picked the chamber in which they received the cocaine.
