I haven’t read the entire thing yet, so maybe I am missing something, but isn’t the globus pallidus inhibitory? In this you stated that it amplifies signals. there should be a path from the cortex to the subthalamic nucleus that where the globus pallidus shuts down the idea fed to striatum. I like to think of the striatum as the dad, and the globus pallidus as the mom. Then the cortex is the idea that the kids(thalamus) come up with. The dad and mom both see the idea, and the mom always says no, unless the dad convinces her to do the thing. The globus pallidus internal can also send the thalamus to time out to suppress new ideas.
