Rat Brains on Ecstacy

New Scientist is reporting that rats on ecstacy suffer deteriorating brain function that lasts longer when they are exposed to loud noise. The intension of course is to imply that humans are equally damaged, so guys and girls don't go to the dance club and drop mdma. Aside from the paucity of mdma in what is sold as ecstasy, I find the concept of this experiment questionable, let alone the design itself. To equate rat hearing function with human hearing is laughable. Yes they are both mammals, and yes the same kind of function occurs in interpreting sound, but the rat devotes more (and different) brain to sound interpretation than the human does - not to mention that the rat can hear further into the high frequency than humans. So would you perhaps expect a difference in reaction if you play maximum club level white noise to a more sensitive creature? I think this is science as politics, and its a shame to see New Scientist buy into it.
