I spent some time looking into this question myself using the AX-CPT / DPX tasks: e.g. pubmed.ncbi.nlm.nih.gov/31368085/
The expected proactive theta patterns were certainly present, but about 1/3 as big as reactive control.

Looking forward to reading it in more depth. Any chance to look at dmPFC-dlPFC theta band phase sychnrony?

I'd put frontal theta phase synchrony as a mechanism for implementing control at the top of the successes. Theoretically motivated, specific to control evocation, specific to theta, and *highly* replicated (see Fig 9.2: awspntest.apa.org/record/2023-...) 2/2

I've always thought of the problem as a more theoretical vs. atheoretical issue. Everyone can run methods and show connectivity. But *why* are these effects there? When are they *not there*? What is the connectivity *doing*? Few studies even bother to ask. 1/2

Really looking forward to reading this. Your work was very influential for a recent review article I wrote - and now this preprint seems even more relevant: osf.io/preprints/ps...

Neat thought about sign-tracking. But I don't see any evidence that RewP is involved in any RL or salience-related enhanced neural response to an imperative cue. It's feedback only (as far as we know). Response, volition, attention, meaning: all these enhance ERPs; RewP isn't any different.

In these cases we cite, the interspersed proxy cues are highly predictive of the desired outcome, so I think they end up being the same thing. (e.g. when you see ♦️, press 👈 to get a 😀. But before the 😀 you get a 🍇. This 🍇==😀 for the purposes of the RewP)

1) We review its elicitation, quantification, generation & theoretical interpretation.
2) We challenge the assumption of a single bipolar signal (+RPE to -RPE) in the difference wave.
3) We propose a refined theoretical account: from reward receipt to a more nuanced signal of goal attainment.

Yeah I learned that from writing a paper with you. I think you have the shortest responses I've ever seen. Brevity is...
... good.

Yeah only one guy I know had the cojones to try something like that: www.jneurosci.org/content/32/2...
