It looks like a lot of the details of the experiment are purposely left out of the application as they are looking to appeal to the general public and I think that is a smart thing to do. Putting details into the application would make people's eyes glaze over, so keeping it simple was the correct way to go.
From my understanding of their proposal, they are looking to do something quite common in neuroscience research. While I personally haven't done autoradiography, I know people who have and it is a commonly(although not much now) technique that has been used numerous times. To do this as a new lab, without university support would be dangerous, unethical and worrisome, but it seems clear this lab is already established.
What they propose seems to be an initial step in a nice project that could lead to something useful. Doing the anatomy (they are basically trying to see where the drug binds within the brain first) and then the molecular techniques makes sense and I wish more labs did stuff like this. As a neuroscientist, I applaud their going outside of the system and I'm happy to see that they will share their data with everyone.
