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...

You got a template?

Excited to share our new paper: whether STN stimulation increases impulsivity depends on theta frequency. 🧠🤓 Grateful to have contributed alongside such a fantastic team! Rachel, Kumar,

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)

I remember when you did eeg!

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.

Big news. After 48 drafts, Clay Holroyd and I are excited to present a narrative review and new theoretical summary on our favorite sensitive & specific EEG marker of reward receipt - the Reward Positivity: tinyurl.com/yzy98rur

Congratulations

Excited to share my first 1st & corresponding author preprint!

Here, I examine an EEG component, the Reward Positivity (RewP), during inference-based decision-making w/Holly Crowder, Peter Kakalec, Lam Duong, Craig McDonald, & Jim Thompson.

That student's name? Seth Abrutyn circa 1998.

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...

As more of a biologist than a modeler, I'm comfortable assuming that value is more complex than what RL accounts for. So ... not terribly surprised that a biological system acts like a complex affective/motivational register and not a highly restricted see-saw. (RewP as well, as you surely know)

Finally got time to read it. Great paper. Here's my review:

Major points: Why not just call it a P3a?

Minor points: Your ERPs are all upside down
