In fairness to the world of neuro's Braak et al were discussed at the WPC, though I did not attend that session, so am not sure what conclusions were drawn. I believe that Braak's hypothesis includes some of this stuff. Rick, correct me if I am wrong. However, to think that this stuff is part of mainstream thinking would be to stretch a point.........

Interestingly one of the reasons that the duodopa pump treatment works so well is because of dopamine uptake in the gut....... it gets it to the right place.

Not quite the same topic, but it is related.......
