I especially like the idea of dopamine and basal ganglia signals controlling prefrontal cortex during goal selection. It really gets us close to truly vanquishing the homunculus. I looked a bit at what was happening in basal ganglia during cognitive control (in the study described in this post) and wasn't able to make a whole lot of sense of it. The head of the caudate nucleus showed some (inconsistent) increases during cognitive control. I wasn't able to find a clear interpretation, though I may need a dataset with a better encoding-period manipulation to better test O'Reilly's theories. One thing about O'Reilly's model that has been unclear to me is how the dopamine/BG system received inputs in order to predict reward. Is there a feedback loop from prefrontal cortex, or do sensory stimuli directly impinge on VTA/basil ganglia? Yes, I am very familiar with Dr. O’Reilly’s work and am a big fan.

I wonder if you're familiar with Randy O'Reilly's computational theory of cognitive control. It's incomplete, and more work like yours needs to be done to extend our understanding. However, this theory is important because a) it works at a lower, more mechanistic level, and b) because it's closely based on evidence from several different levels of research. Just wondering what the rest of the community thinks of the type of work coming out of our lab. In the interest of full disclosure, I'm a postdoc in Dr. O'Reilly's lab. I think the type of work his lab is doing is has an important role in figuring out how cognitive control works, along with empirical studies such as your own. Interesting study, good work!
