You can't exactly pull some brain matter out to send to the lab, which makes research very difficult.

Of course not in humans. Though can probably be done experimental with animals. With all the side effects and trade-offs involved with these drugs surely they had to be doing something like it?

I was mostly thinking maybe sample the blood or spinal fluid, or use imaging tracing markers to see how the imbalance manifests and then it can be corrected.
