There are/were several sources reporting on these "results" from the Swedish Institute, here:

They all say the same thing although the source listed first above has the most detail. Not sure what to make of it, as Laura pointed out, what's their point? PWP have to take ldopa, there's currently not much in the way of options if you want to be able to move.

Additionally, I don't believe salamanders even have a BBB, so why they used that creature for their research is a mystery. To my knowledge, the only mammal with a brain structure like ours, meaning and including the complex BBB, is the Rhesus monkey.
