Was the hope of generating data such as this. It is almost insulting that these observations are dismissed as "tricks." It would be different if it was simply our ignorance, but the researchers are the same for much of this.

And, while many of us lack the vocabulary of academia, a good researcher could overcome that with the right questions. Any lurkers out there want to explore this? Not holding my breath, of course.

It is not entirely off the wall to suggest that ldopa's success at the symptomatic level has led to the wrong conclusions. Maybe it is more a matter of data processing of stimuli than we think. There are some interesting similarities between schizophrenia, autism, and PD for example. Sensory overload is a problem in all three as well as stress response.
