Losing steam? You mean the theory was discredited because there isn't any proof whatsoever of it being true and we don't have the means currently to prove or disprove it (measuring said chemicals while the brain is alive). I'd say that's a little more than losing steam. That's on par with the anti global warming campaign as far as science goes. But it's a nice story (think fiction) so people like to keep regurgitating it, including psychiatrists and psychologists who all should know better. But hey, it does sell a ton of drugs, so its primary purpose has been achieved.
