I don't know the specifics but, like you, would like to know more. I found it interesting to read fairly recently about the patient who received an experimental treatment and, a year later, still showed significant amelioration of symptoms even though his dopamine levels, which had risen with treatment, had declined to their original levels. This suggests to me that dopamine depletion is only part of a complex interaction and focusing on dopamine alone is not going to get us where we need to go.
